1.4. Terminologies and acronyms
This section will define commonly used terms in this manual. These terms are related to
Internetworking, and defined in regards to their use with Pro Series.
z MAC address
On a local area network or other network, the MAC (Media Access Control) address is the computer’s
unique hardware number. (On an Ethernet LAN, it is the same as the Ethernet address.)
It is a unique 12-digit hardware number, which is composed of 6-digit OUI (Organization Unique
Identifier) number and 6-digit hardware identifier number. The Pro Series has the following MAC
address template: 00-01-95-xx-xx-xx. The MAC address can be found on the bottom of the original
package.
z Host
A user’s computer connected to the network
Internet protocol specifications define “host” as any computer that has full two-way access to
other computers on the Internet. A host will have a specific “local” or “host number” that, together with
the network number, forms its unique IP address.
z Session
A series of interactions between two communication end points that occur during the span of a single
connection
Typically, one end point requests a connection with another specified end point. If the specified
end point replies, and agrees to the connection, the end points then take turns exchanging commands
and data (“talking to each other”). The session begins when the connection is established at both ends
and terminates when the connection is ended.
z Client/Server
Client/server describes the relationship between two computer programs in which one program, the
client, makes a service request from another program, the server, which fulfills the request.
A server is a computer program that provides services to other computer programs on one or
many computers. The client is the requesting program or user in a client/server relationship. For
example, the user of a Web browser is effectively making client requests for pages from servers all
over the Web. The browser itself is a client in its relationship with the computer that is getting and
returning the requested HTML file. The computer handling the request and sending back the HTML file
is a server.

two network interfaces don’t work together. Please select a network interface to operate.
3.1.2. Using a Static IP Address
When using a Static IP address, the user must manually specify all the configuration parameters
associated with the IP address of the Pro Series. These include the IP address, the network subnet
mask, the gateway computer and the domain name server computers. This section will look at each of
these in more detail.
Note: The Pro Series will attempt to locate all this information every time it is turned on.
z IP address
A Static IP address acts as a “static” or permanent identification number. This number is assigned to
a computer to act as its location address on the network. Computers use these IP addresses to
identify and talk to each other on a network. Therefore, it is imperative that the selected IP address be
both unique and valid in a network environment.
Note: 192.168.1.x will never be assigned by and ISP (Internet Service Provider). IP addresses using
this form are considered private. Actual applications of the Pro Series may require access to public
network, such as the Internet. If so, a valid public IP address must be assigned to the user’s computer.
A public IP address is usually purchased or leased from a local ISP.
z Subnet mask
A subnet represents all the network hosts in one geographic location, such as a building or local area
network (LAN). The Pro Series will use the subnet mask setting to verify the origin of all packets. If
the desired TCP/IP host specified in the packet is in the same geographic location (on the local
network segment) as defined by the subnet mask, the Pro Series will establish a direct connection. If
the desired TCP/IP host specified in the packet is not identified as belonging on the local network
segment, a connection is established through the given default gateway.
z Default gateway
A gateway is a network point that acts as a portal to another network. This point is usually the
computer or computers that control traffic within a network or a local ISP (Internet service provider).
The Pro Series uses the IP address of the default gateway computer to communicate with hosts
outside the local network environment. Refer to the network administrator for a valid gateway IP

address.
z Primary and Secondary DNS
The DNS (Domain Name System) server is used to locate and translate the correct IP address for a
requested web site address. A domain name is the web address (i.e. www.yahoo.com) and is
usually easier to remember. The DNS server is the host that can translate such text-based domain
names into the numeric IP addresses for a TCP/IP connection.
The IP address of the DNS server must be able to access the host site with the provided domain
name. The Pro Series provides the ability to configure the required IP addresses of both the Primary
and Secondary DNS servers addresses. (The secondary DNS server is specified for use when the
primary DNS server is unavailable.)
3.1.3. Using DHCP
Dynamic Host Configuration Protocol (DHCP) is a communications protocol that lets network
administrators manage and automate the assignment of IP addresses centrally in an organization’s
network. DHCP allows the network administrator the ability to supervise and distribute IP addresses
from a central point and automatically send a new IP address when a computer is plugged into a
different network location.
When in static IP mode, the IP address must be entered manually at each computer. If a computer is
moved to another network location, a new IP address must be assigned. DHCP allows all the
parameters, including the IP address, subnet mask, gateway and DNS servers to be automatically
configured when the IP address is assigned. DHCP uses a “lease” concept in assigning IP
addresses to a computer. It limits the amount of time a given IP address will be valid for a computer.
All the parameters required to assign an IP address are automatically configured on the DHCP server
side, and each DHCP client computer receives this information when the IP address is provided at its
boot-up.
Each time the device is reset, the Pro Series broadcasts a DHCP request over the network. The reply
generated by the DHCP server contains the IP address, as well as the subnet mask, gateway address,
DNS servers and the “lease” time. The Pro Series immediately places this information in its memory.
Once the “lease” expires, the Pro Series will request a renewal of the “lease” time from the DHCP
server. If the DHCP server approves the request for renewal, the Pro Series can continue to work
with the current IP address. If the DHCP server denies the request for renewal, the Pro Series will start
the procedure to request a new IP address from the DHCP server.
Note: While in DHCP mode, all network-related parameters for the Pro Series are to be configured
automatically, including the DNS servers

A DHCP sever assigns IP addresses dynamically from an IP address pool, which is managed by the
network administrator. This means that the DHCP client, i.e. the Pro Series, receives a different IP
address each time it boots up. The IP address should be reserved on the DHCP server side to assure
that the user always knows the newly assigned Pro Series address. In order to reserve the IP address
in the DHCP network, the administrator needs the MAC address of the Pro Series found on the label
sticker at the bottom of the Pro Series.
3.2. WiFi Configuration
The PSx10W has a WiFi interface that supports both 802.11b and 802.11g.
3.2.1. Network type
An AP is most often used to connect the PSx10W to the Ethernet. However, it can also be used to
connect to the Internet. This type of connection is referred as an “infra mode.” On wireless computer
networks, ”Adhoc mode”, also called “peer-to-peer mode”, is a method for PSx10W devices to directly
communicate with each other without an AP. Adhoc mode can be very useful in replacing cables between
existing devices with a wireless connection.
Figure 3-2 Network type configuration
3.2.2. Operation mode configuration
The “Operation mode” is enabled when the “Network type” is Infra mode. The modes are as follows:

3.2.3. List of APs
This menu is enabled when the “Network type” is Infra mode. If the Operation mode is not “Connect
any”, the AP to which the PSx10w connects should be registered. If you use ADD or REMOVE
command, you should use SAVE command. In case, ‘Save & Apply’ command, the changed things are
reflected in systems directly.

3.3. SNMP Configurations
The Pro Series has the SNMP (Simple Network Management Protocol) agent supporting SNMP v1
and v2 protocols. Network managers like NMS or SNMP Browser can exchange information with Pro
Series, as well as access required functionality.
SNMP protocols include GET, SET, GET–Next, and TRAPs. With these functions, a manager can be
notified of significant events (TRAPs), query a device for more information (GET), and make changes
to the device state (SET). SNMPv2 adds a GET–Bulk function for retrieving tables of information and
security functions.
With the SNMP configuration panel, the user can configure MIB-II System objects, access control
settings and TRAP receiver settings. The manager configured in this menu can perform both
information exchange and action control. Figure 3- shows a SNMP configuration screen via a web
interface.

3.3.1. MIB-II System objects Configuration
MIB–II System objects configuration sets the System Contact, Name, Location, and Authentication-
failure traps used by the SNMP agent of the Pro Series. These settings provide the values used for the
MIB-II sysName, sysContact, sysLocation, sysService and enableAuthenTrap.
Brief descriptions of each object are as follows,
z sysContact: Identification of the contact person for the managed system (Pro Series), and a
description of how to contact the person.
z sysName: Name used to identify the system. By convention, this is the fully qualified domain
name of the node.
z sysLocation: The physical location of the system (e.g., Room 384, Operations Lab, etc.).
z sysService(Read Only) : A series of values, separated by commas, that indicate the set of
services that the system provides. By default, Pro Series only supports an Application(7) service
level.
z EnablePoweronTraps: Indicates whether the SNMP agent process is permitted to generate
power-on traps.
z EnableAuthenTrap: Indicates whether the SNMP agent process is permitted to generate
authentication-failure traps. The value of this object overrides any configuration information; as
such, it provides a means whereby all authentication-failure traps may be disabled..
z EnableLoginTrap: Indicates whether the SNMP agent process is permitted to generate system
login traps for console, telnet and Web access.
If users need support for adding or modifying MIBs, please contact Sena technical support.
For more information about the MIBs and SNMP, see the RFCs 1066, 1067, 1098, 1317, 1318 and
1213.
3.3.2. Access Control Configuration
Access Control defines accessibility of managers to the Pro Series SNMP agent. Only the manager
set in this menu can access Pro Series SNMP agent to exchange information and control actions. If
there is no specified IP address (all IP address are defaulted to 0.0.0.0), a manager from any host can
access the Pro Series SNMP agent.
3.3.3. Trap Receiver Configuration
The Trap receiver defines managers, which can be notified of significant events (TRAP) from the Pro
Series SNMP agent.

3.3.4. Management using SNMP
The Pro Series can be managed through the SNMP protocol using NMS (Network Management
System) or SNMP Browser. Before using the NMS or SNMP Browser, the user must set the access
control configuration properly so that the Pro Series permits host access where the NMS or SNMP
Browser is executed. Figure 3- shows a screen shot of a typical SNMP browser with MIB-II OIDs of the
Pro Series SNMP agent.

3.4. Dynamic DNS Configuration
When users connect the Pro Series to a DSL line or use a DHCP configuration, the IP address might
be changed whenever it reconnects to the network. It can therefore be very difficult to post all related
contacts for each new IP address. In addition, if the administrator only has access through the remote
console, there is no way to know if an IP address has changed, or what the new IP address is.
A Dynamic DNS service is provided by various ISPs or organizations to deal with the above issue. By
using the Dynamic DNS service, users can access the Pro Series through the hostname registered in
the Dynamic DNS Server regardless of any IP address change.
By default, the Pro Series only supports Dynamic DNS service offered at Dynamic DNS Network
Services, LLC (www.dyndns.org). Contact Sena technical support for issues regarding other Dynamic
DNS service providers.
To use the Dynamic DNS service provided by Dynamic DNS Network Services, the user must set up
an account in their Members’ NIC (Network Information Center - http://members.dyndns. org). The
user may then add a new Dynamic DNS Host link after logging in to their Dynamic DNS Network
Services Members NIC.
After enabling the Dynamic DNS service in the Dynamic DNS Configuration menu, the user must enter
the registered Domain Name, User Name, and Password. After applying the configuration change,
users can access the Pro Series using only the Domain Name.
Figure 3- shows the Dynamic DNS configuration web interface.

3.5. SMTP Configuration
The Pro Series can send an email notification when the number of system log messages reaches to
certain value and/or when an alarm message is created due to an issue with serial port data. The user
must configure a valid SMTP server send these automatically generated emails. The Pro Series
supports three SMTP server types:
• SMTP without authentication
• SMTP with authentication
• POP-before-SMTP
These examples can be seen in Figure 3-3. Required parameters for each SMTP configuration
include:
• SMTP server IP address
• SMTP user name
• SMTP user password
• Device mail address
The device mail address specifies the sender’s email address for all log and alarm delivery emails.
SMTP servers often check only the sender’s host domain name of the email address for validity.
Consequently, the email address set for the device can use an arbitrary username with a registered
hostname (i.e. arbitrary_user@yahoo.com or anybody@sena.com).
The SMTP user name and SMTP user password are required when either SMTP with authentication
or POP-before-SMTP mode is selected.

3.6. IP Filtering
The Pro Series prevents unauthorized access using an IP address based filtering method. The users
can allow one of the following scenarios by changing the parameter settings:
- Any host cannot access a specific service of the Pro Series
- Only one host of a specific IP address can access a specific service of the Pro Series
- Hosts on a specific subnet can access a specific service of the Pro Series
- Any host can access a specific service of the Pro Series
The IP filtering feature is intended to control access to Telnet console, SSH console, NFS, Web server
or each port, which may be enabled or disabled. The factory default of the filtering feature is “All
services and ports are accessible from any host”.
The meanings of each parameter in IP filtering configuration are as follows,
z Interface
Apply IP filtering rule to the incoming packet of Pro Series. This is fixed parameter as
eth0(Read-Only).
z Option and IP address/mask
Input field to describe a specific range of host on the network. The user may allow a host or a
group of hosts to access the Pro Series. The user must then enter the IP address and subnet of
access. Any user on a remote host must stay in the specified subnet boundary to access the
Pro Series. To allow only a specific host to access the Pro Series, enter the IP address of the
specific host and just give 255.255.255.255 for the subnet with Normal option. To allow any
hosts to have access to the Pro Series, give 0.0.0.0 for both of the IP address and subnet with
Normal option also. Refer to Table 3-2 for more details.

z Service
Service to which will be applied to the IP filtering rule. User can select one of Telnet, SSH, NFS,
HTTP, HTTPS or each serial port
z Chain rule
Set the basic rule for the host to access the Pro Series as one of Accept, Drop or Reject.
Figure 3-42 IP filtering Configuration
The Pro Series provides a policy option. The policy decides how to treat a packet which isn’t
determined to be dropped or accepted by IP filtering list. For example, in case there is no IP filtering
list and all the services are set to be “Accept all”, the Pro Series won’t respond to any packet whose
destination port is not one of the services if the policy is “DROP” or “REJECT.
Figure 3-53 IP filtering policy
The Pro Series also provides users with simple configuration way to block a specific service(s) or
serial ports from all hosts. If the user should set any service option as “Drop all” or “Reject all”, then all
access to the service from the network will be blocked.

3.7. SYSLOG server configuration
The Pro Series supports the use of a remote message logging service, SYSLOG service for the
system and port data logging. To use the remote SYSLOG service, the user must specify the
SYSLOG server’s IP address and the facility to be used. Figure 3-7 shows the SYSLOG server
configuration page which is located in the Web interface.

38
Figure 3-75 SYSLOG server configuration
To receive log messages from the Pro Series, the SYSLOG server must be configured as “remote
reception allowed”. If there is a firewall between the Pro Series and the SYSLOG server, there must
be a rule that allows all outgoing and incoming UDP packets to travel across the firewall.
The Pro Series supports SYSLOG facilities from local0 to local7. The user can employ these
facilities to save messages from the Pro Series separately in the SYSLOG server.
If the SYSLOG service is enabled and the SYSLOG server configuration is properly set up, the user
may configure the storage location for the system log or port data log of the Pro Series as SYSLOG
server. For more information about the configuration of port/system log storage location, please refer
to section, 4.2.8 Port Logging and 5.2 System Logging.
3.8. Locating server
3.8.1. Overview
If users want the Pro Series to work as a server (TCP or UDP), the host acting as a client has to know
the IP address of the Pro Series. However, under the dynamic IP address environment such as DHCP,
arbitrary IP address can be assigned to the Pro Series, which means special consideration is required
to access the current IP address of it. To tackle this problem, the Pro Series can be configured to send
its IP address information whenever it is assigned a new IP address or periodically to a specific server
called locating server. You can operate a specific host as your locating server or you can use your
client host as a locating server simultaneously.
No special library or toolkit to implement locating server is provided. You have to implement your own
application by using the protocol provided below or contact us.
3.8.2. Locating server configuration
Locating server configuration screen is shown in Figure 3-8. You have to configure locating server IP
address, locating server UDP port number and connection time interval as well as to use locating
server feature or not. Initially locating server feature is configured as “Disabled”.

3.8.3. Locating server communication protocol
When the Pro Series sends its IP address information to the locating server, data format will be as
follows:
Description Magic Cookie Data(0) Data(1) … Data(n)

Value F1-AA-AA-BC
Data(n) format

5 IP address 4
6 Local ports* 1 or 4 or 8
Note:
Local ports: Each 2 byte data represent current local port setting of the corresponding serial port. Local ports data
length of PSx10W should be 2 bytes. Configured local TCP (or UDP) port numbers for each serial port are filled
in the serial port number order base, (i.e. TCP or UDP port number for serial port 1 first). If serial port is disabled,
the local port number of that serial port is regarded as 0.
Example of the PS110W:
If port number = 7001 (1B59h), Local ports data = 1Bh, 59h
If serial port is disabled, Local port data = 00h, 00h
Example of the PS210W:
Port1 = 7001 (1B59h), Port2 = 7010 (1B62h), Port3 = Disable, Port4 = 7004(1B5Ch)
Local ports data = 1Bh, 59h, 1Bh, 62h, 00h, 00h, 1Bh, 5Ch

3.9. NFS server configuration
The Pro Series supports NFS (Network File System) service for system or port data logging functions.
To use this service, the user must specify the IP address of a NFS server and the mounting path on
the NFS server. Figure 3-9 displays the NFS server configuration page located in the web
configuration interface..
Figure 3-97 NFS server configuration
To store the Pro Series log data to the NFS server, the NFS server must be configured as “read and
write allowed”. If there is a firewall between the Pro Series and the NFS server, there must be a rule
that allows all outgoing and incoming packets to travel across the firewall.
If the NFS service is enabled and the NFS server configuration is properly set up, the user may
configure the storage location for the system log or port data log of the If there is a firewall between
the Pro Series and the SYSLOG server, there must be a rule that allows all outgoing and incoming
UDP packets to travel across the Pro Series as the NFS server. For more information about the
configuration of the port/system log storage location, please refer to section, 4.2.8 Port Logging and
5.2 System Logging.
3.10. TCP service configuration
If a TCP session is established between two hosts, the connection should be closed (normally or
abnormally) by either of the hosts to prevent the lock-up of the corresponding TCP port. To prevent
this type of lock-up situation, the Pro Series provides a TCP “keep-alive” feature. The Pro Series will
send packets back and forth through the network periodically to confirm that the network exists . The
corresponding TCP session is closed automatically if there’s no response from the remote host.
To use the TCP “keep-alive” feature with the Pro Series, the users should configure three parameters
as follows:
z TCP keep-alive time:
This represents the time interval between the last data transmission and keep-alive packet
서식 있음: 글머리 기호 및
번호 매기기
서식 있음: 글머리 기호 및
번호 매기기
삭제됨:
삭제됨:
삭제됨:
41
submissions by the Pro Series. These “keep-alive” messages are sent to the remote host to
confirm that the session is still open. The default time value is 15 sec.
z TCP “keep-alive” probes:
This represents how many “keep-alive” probes will be sent to the remote host, until it decides that
the connection is dead. Multiplied with the “TCP ‘keep-alive’ intervals”, this gives the time that a
link is forced to close after a “keep-alive” packet has been sent for the first time. The default is 3
times
z TCP keep-alive intervals:
This represents the waiting period until a “keep-alive” packet is retransmitted. The default value is
5 seconds.
By default, the Pro Series will send the keep-alive packets 3 times with 5 seconds interval after 15
seconds have elapsed since the time when there’s no data transmitted back and forth.

4. Serial Port Configuration
4.1. Overview
The serial port configuration capability allows the user to configure the host mode of each port, serial
communication parameters, cryptography, port logging parameters and other related parameters.
The serial port’s host mode can be set as any of the following:
z TCP :
The Pro Series operates as a TCP server and client. If the connection is not established, it
accepts all incoming connections from any registered remote hosts and connects to the registered
remote hosts if there is any data from the serial devices. Otherwise, it will send data back and
forth. In summary, the Pro Series will work as if it is virtually connected to the remote host.
z UDP :
The UDP mode operation is similar to that of TCP mode except that it is based on UDP protocol.
z Modem emulation :
Select this mode when the serial device becomes ready to support modem AT commands or
users want to perform the session control by using AT commands. Only TCP session is supported.
With the port-logging feature while in console server mode, the data sent through the serial port is
transferred to MEMORY or NFS server’s storage. The user can also define keywords for each serial
port that will trigger an email or SNMP trap notification. This will enable the user to monitor the data
from the attached device.
Using MEMORY to store data will result in loss of all information when the Pro Series is turned off.
Use the NFS server to preserve the serial port log data.
The serial ports can be configured individually or all at once. Table 4-1 summarizes the
configuration parameters related to the serial port configuration.

Figure 4-3 Port title configuration
4.2.3. Host Mode Configuration
The Pro Series operating mode is called the “host mode.” Three host modes are available: TCP mode,
UDP mode, Modem emulation mode.
TCP mode
The Pro Series works as both TCP server and client. This mode works for most applications, since it
will transfer the data either from serial port or from TCP port. If there is no connection established on a
TCP port, the TCP port accepts a connection request from any registered remote hosts and relays the
transmitted data to the coupled serial port. If there is any data from the serial port, it connects to the
registered remote hosts and redirects the data.
UDP mode
The UDP mode operation is similar to that of TCP mode except that it utilizes UDP protocol.
Modem emulation mode

perform the session control by using AT commands. Only TCP session is supported.

Figure 4-4 Host mode configuration (TCP mode)
4.2.3.1. TCP mode
For easier understanding of TCP modes, a simplified State Transition Diagram is often used. And to
help users understand the diagram, the TCP state of the Pro Series is briefly described as follows.
[Listen]
It represents “a waiting for a connection request from any registered remote host”. It is a default
start-up mode when it is set as TCP mode.
[Closed]
It means “no connection state”. If the data transfer between a remote host and the Pro Series is
completed, the state is changed to this state as a result that either of the remote host or the Pro
Series sent a disconnection request. After this, the state is automatically changed to [Listen] mode.
[Sync-Received]
The state is changed from [Listen] to [Sync-Received] if one of the remote hosts has sent a
connection request. If the Pro Series accepts the request, the state is changed into [Established].
[Sync-Sent]
If the Pro Series has sent a connection request to a remote host, the state is changed from
[Closed] to [Sync-Sent]. This state is maintained until the remote host accepts the connection

47
request.
[Established]
It represents “an open connection”. If one of the hosts, the remote host or the Pro Series, accepts
a connection request from the other, the connection is opened and state is changed into
[Established].
[Data]
When it is in [Established] state, data from a host will be transferred to the other one. For easier
understanding of the TCP session operation, we called the state as [Data] state when actual data
transfer is performed. Actually, the [Data] mode is a part of [Established] state as is described in
the RFC 793 [Transmission Control Protocol]. This is a normal state for the data transfer phase of
the connection.
The Pro Series works as either TCP server or client according to the situation. This will be the typical
mode for most applications, since it will transfer the data either from serial port or from TCP port. The
default TCP state is [Listen] which is the same as that of TCP server mode.
1) Typical State Transition
[Listen] --> [Sync-Received] --> [Established] --> [Data] --> [Closed] --> [Listen]
Or
[Listen] --> [Sync-Sent] --> [Established] --> [Data] --> [Closed] --> [Listen]
The initial state is [Listen]. If there are data coming from the serial port, it will connect to the remote
host as a TCP client and then transfer data through the TCP port. If there is incoming connection
request from the remote host, it will accept the connection as a TCP server, and then transfer data
through the serial port. Thus, users can assume that the Pro Series is always connected to the
specified remote host.
2) Operations
Serial data transfer
Whenever the serial device sends data through the serial port of the Pro Series, data will be
accumulated on the serial port buffer of the Pro Series. If the buffer is full or the time gap reaches
the inter-character timeout (See Options in section 4.4 for details on inter-character timeout), the
Pro Series connect to the registered remote host(s). If a TCP session has not been established
yet. If the Pro Series succeeds in connecting to the remote host, the data in the serial port buffer
will be transferred to the host. Otherwise, all the data stored in the buffer will be cleared.
Session disconnection
The connected session will be disconnected when the remote host sends disconnection request

48
or when no data transfer activity is found through the serial port for certain amount of time, which
is “Inactivity timeout” (See Options in section 4.4 for details on Inactivity timeout). All the data
remained in the serial port buffer will be cleared when it is disconnected.
Connection request from remote host
All the incoming TCP connection requests will be rejected in TCP client mode.
3) Parameters
TCP listening port
This is the TCP port number through which a remote host can connect a TCP session, and, send
and receive data. Incoming connection request(s) to the ports other than TCP Listening Port will
be rejected. The Pro Series does restrict the port number from 1024 to 65535 and if it is set as 0
only outgoing connection is permitted. (TCP server mode)
User authentication
If the User authentication option is enabled, the user can access the port after entering the correct
user ID and password. Please refer to the section 5.9 User administration for details of user
management.
Telnet protocol
In TCP mode, Pro Series supports Telnet Com Port Control Option (RFC2217 compliant) so that
user can control serial parameters like baud rate, data bits and flow control option using his local
RFC2217-compliant Telnet client program. (Please refer to section 4.2.6 Serial port parameters
for more detail information about serial parameters)
Usually this option is used with the RFC2217-compliant COM port redirector so that user can
control parameters of serial ports of Pro Series using his serial port application program.
For this purpose, SENA OEM version of Serial/IP from Tactical Software, LLC is bundled with Pro
Series. Please refer to documentations of Serial/IP for more detail information about using the
COM port redirector. (Please refer to section Appendix 5 Using Pro Series with Serial/IP for more
detail information)
Max. allowed connection
The Pro Series supports up to 8 multiple connections from external host(s) to the serial port. If
there are remote host connections by the remote host list configuration already, possible number
of connection will be reduced (Max. allowed connection - remote host(s) connected already). For
example, if user set Max. allowed connection as 8 and if there are 3 connections from Pro Series
to remote hosts, which are configured in the remote host list, then maximum number of
connection from external hosts to a serial port will be reduced to 5. For more detailed information

49
for remote host list configuration, please refer to 4.2.4 Remote host configuration section.
Cyclic Connection
If Cyclic Connection function is enabled, the Pro Series will make an attempt to connect to the
user-defined remote host(s) at a given interval even if there’s no incoming serial data from the
device connected to that serial port. If there is data on the remote host(s) to be sent to serial
device, it can be transferred to the serial device via Pro Series’ serial port after the connection is
established. Eventually, users can monitor the serial device periodically by making the remote
host send the serial command to the Pro Series whenever it is connected to the remote host. This
option is useful when users need to gather the device information periodically even if the serial
device does not send its data periodically. Figure 4-5 shows the State Transition Diagram of the
session operations in TCP mode.
Socket ID
When many Pro Series devices connects a same remote host(s), sometimes it is needed to
identify the device. In this case, Socket ID is available for identification of each device. Pro Series
send the Socket ID string before starting the data transmission. User can define Socket ID with a
specific string. In TCP mode, specified Socket ID strings are sent once at the time of establishing
TCP connection.
TCP Nagle algorithm
Modern TCP implementations include a mechanism, known as the Nagle algorithm, which
prevents the unnecessary transmission of a large number of small packets. This algorithm has
proved useful in protecting the Internet against excessive packet loads. However, some
applications suffer performance problems as a result of the traditional implementation of the Nagle
algorithm.(An interaction between the Nagle algorithm and TCP’s delayed acknowledgement
policy can create especially severe problems, through a temporary “deadlock.”) TCP Nagle
algorithm can be disabled or enabled through this option.
Inactivity Timeout
When Inactivity Timeout function is enabled, connection between remote host(s) and Pro Series
will be closed automatically if there is no data transmission during the value which is set in
Inactivity Timeout configuration.

4.2.3.2. UDP mode
The UDP mode operation is similar to that of TCP mode except that it is based on UDP protocol and
only one pre-defined remote host is able to communicate with the Pro Series. Users do not have to
configure cyclic connection, since UDP is a connectionless protocol.

Figure 4-6 Host mode configuration (UDP mode)
1) Operations
If a remote host sends a UDP datagram to the one of UDP Local port of the Pro Series, Pro Series first
checks whether it is from one of the hosts configured on remote host configuration. If the remote host
is one of the hosts configured on remote host configuration, then Pro Series transfers the data through
the serial port. Otherwise, the Pro Series discards the incoming UDP datagram. But user can force Pro
Series accept all incoming UDP datagram regardless remote host configuration by setting Accept UDP
datagram from unlisted remote host parameter as ‘Yes’. If there is any incoming data from the serial
port, the Pro Series transfers the data to the remote host defined on remote host configuration. If the
remote port is not opened, the Pro Series will not transfer the data.
2) Parameters
UDP receiving port
The concept is the same as TCP listening port. See TCP mode parameters in the section 4.2.3.1
for details.
Max. allowed connection
The concept is the same as that of TCP communication. See TCP mode parameters in the

Accept UDP datagram from unlisted remote host
If Accept unlisted (Accept UDP datagram from unlisted remote host) function is set as ‘No’, Pro
Series will accept only incoming UDP datagram from the remote host(s) configured on remote
host configuration. On the contrary if Accept unlisted function is set as ‘Yes’, Pro Series will
accept all incoming UDP datagram regardless remote host configuration.
Send to recent unlisted remote host
If Send unlisted (Send to recent unlisted remote host) function is set as ‘Yes’, Pro Series sends
data to the remote host, which has connected Pro Series recently. Recent unlisted remote host is
a remote host, which has accessed a corresponding serial port of Pro Series but is not configured
on remote host configuration. Surely, Pro Series also send data to the hosts, which are configured
on remote host configuration. If Send unlisted function is set as ‘No’, Pro Series sends data only
to the host(s) which are configured on remote host configuration. Pro Series maintains a recent
unlisted remote host during the Inactivity Timeout.
Inactivity Timeout
In UDP mode, Inactivity Timeout is used in maintaining recent unlisted remote host. If there is no
data transmission between unlisted remote host and serial port of Pro Series during Inactivity
Timeout, Pro Series will not send data from a serial port to the recent unlisted remote host again.
Namely, Inactivity Timeout in UDP mode is the time maintained recent unlisted remote host list by
Pro Series.
NOTE: If user set Inactivity Timeout as 0 in UDP mode, Pro Series does not allow any new
connection from/to remote host if the number of current remote host exceeds Max. allowed
connection.
Socket ID
When many Pro Series devices connects a same remote host(s), sometimes it is needed to
identify the device. In this case, Socket ID is available for identification of each device. Pro Series
send the Socket ID string before starting the data transmission. User can define Socket ID with a
specific string. In UDP mode, specified Socket ID strings are added to the head of every packet.
4.2.3.3. Modem emulation mode
1) Operations
In modem emulation mode, the serial port process acts as if it is a modem attached to the serial
device. It accepts AT modem commands and answers to them, as modems would do. It also handles
the modem signals correctly. Modem emulation mode is useful in the following cases.

There already exists a modem attached to the users’ serial device.
If users’ serial device already has a modem for phone-line connection, it can be just replaced by
the Pro Series for Ethernet connection. What users need to do is to use an IP address (or domain
name) and port number instead of phone number as a parameter of ATA/ATDT commands.
It is required to send serial data to the multiple remote hosts.
If the serial device should send data to the multiple hosts, modem emulation mode is required.
For example, the first data from the serial device can be sent to the first data acquisition server
and the second to the second server. What user device has to do is to change the IP address (or
domain name) and port number parameters whenever the device sends ATD(T) XXX command.
By using the modem emulation mode of the Pro Series, users can have their serial device connected
to the Ethernet network easily, which is cheaper than using phone line modem. Table 4-2 is a
summarized AT command table which is supported by the Pro Series. Figure 4-7 shows the typical
case of the serial port command flow when ATDA command is used to connect to the Ethernet network.

Figure 4-7 Typical case of command/data flow of modem emulation mode
In modem emulation mode, user can also set specific phone number to host address/port mapping
table. If user set the phone number to host address/port mapping table as shown on Figure 4-8, Pro
Series will try to connect to port 7001 of 192.168.1.1 host by the ‘atdt5737772’ command in modem
emulation mode.
2) Parameters
Phone number to host address mapping table
In modem emulation mode, user can set a specific phone number to host address/port mapping
table. If user set the phone number to host address/port mapping table as shown on Figure 4-8,
Pro Series will try to connect to port 6001 of 192.168.0.100 host by the ‘atdt25737772’ command
in modem emulation mode.
CONNECT string in non-verbose mode (ATV0) and CONNECT string in verbose mode
(ATV1)
In modem emulation mode, the Pro Series responds to the AT command according to result code
in Table 4-3 by default. But there are some cases that device requires different form of response
code for remote host connection. For example, when the Pro Series connects the remote host, it
replies “1”(if ATV0 command is set) or “CONNECT” (if ATV1 command is set) result code by
default. But if user needs “12” (if ATV0 command is set) or “CONNECT 9600” (if ATV1 command

shown on Figure 4-8.
Respond to AT&Cn, AT&Wn and AT&Zn with
For the following three AT commands,
AT&Cn, AT&Wn, AT&Zn
User can select the response as one of OK or ERROR.
Command echo delay(ms)
AT commands that are entered by user can be echoed with a delay specified in this menu.
This is useful if user uses modem emulation mode in RS485 mode.
Default command echo
User can disable or enable echo of AT command that is entered by user in this menu.
(Same functionality to ATEn command)
Default data mode
User can select the TCP data mode between Raw TCP mode and Telnet binary mode. The Raw
TCP means that there is no application protocol over the TCP protocol. The Telnet binary mode
means that there is Telnet protocol over the TCP protocol. The Telnet binary mode supports the
Telnet COM Port Control Option defined by RFC2217. When selecting this option with a COM
Port Redirector compatible with RFC2217, user is able to control the serial port parameter of the
Pro Series through a serial port application such as Hyperterminal.

4.2.4. Remote host configuration
Remote host configuration is the list of hosts that will receive data from serial port of Pro Series when
there is data transmission from the serial port of the Pro Series.
In TCP mode, user can also configure secondary remote host (Backup host) that will receive data from
serial port if Pro Series fails to connect to primary remote host. If a connection to the primary remote
host can be made, Pro Series dose not send data to secondary remote host until connection to
primary remote host failed. And the maximum possible number of primary remote host is limited up to
4 remote connections.
In UDP mode, user can only configure a primary remote host because there is no way for Pro Series
to check status of primary remote host, so secondary remote host is meaningless.
The maximum number of remote host is limited up to 4 in the Pro Series. Figure 4-9 shows Remote
host configuration pages of the Web UI. (TCP mode)
User can also set any effective domain name as Host IP address in the Remote host configuration.

4.2.5. Cryptography configuration
The Pro Series supports encrypted sessions for only the TCP mode including modem emulation mode
(not UDP mode).
Figure 4-10 Cryptography configuration
4.2.5.1. Secure Sockets Layer(SSL) cryptography method
By setting the cryptography method as SSL, the Pro Series can communicate with another device
supporting SSLv3 cryptography method during encrypted sessions.
SSL was developed by Netscape for use between clients and servers. SSL layers on top of any
transport protocol and can run under application protocols such as HTTP. SSL aims to be secure, fast,
and adaptable to other Web protocols. SSL provides data security for applications that communicate
across networks. SSL is a transport-layer security protocol layered between application protocols and
TCP/IP.
To initiate SSL sessions, exchange of messages called the SSL handshake is required between two
devices (Server and Client). The SSL protocol uses a combination of public-key and symmetric key
encryption. Symmetric key encryption is much faster than public-key encryption, but public-key

encryption provides better authentication techniques. The handshake allows the server to authenticate
itself to the client using public-key techniques, and then allows the client and the server to cooperate in
the creation of symmetric keys used for rapid encryption, decryption, and tamper detection during the
session that follows. The details of handshake process step involved can be summarized as follows:
1. The client sends the server the client’s SSL version number, cipher settings, randomly
generated data, and other information the server needs to communicate with the client using
SSL.
2. The server sends the client the server’s SSL version number, cipher settings, randomly
generated data, and other information the client needs to communicate with the server over
SSL. The server also sends its own certificate and, if the client is requesting a server resource
that requires client authentication, requests the client’s certificate.
3. The client uses some of the information sent by the server to authenticate the server. If the
server cannot be authenticated, the user is warned of the problem and informed that an
encrypted and authenticated connection cannot be established. If the server can be
successfully authenticated, the client goes on to next step.
4. Using all data generated in the handshake so far, the client (with the cooperation of the server,
depending on the cipher being used) creates the premaster secret for the session, encrypts it
with the server’s public-key (obtained from the server’s certificate, sent in step 2), and sends
the encrypted premaster secret to the server. SSL differ in the way this “shared” master secret
is created
5. If the server has requested client authentication (an optional step in the handshake), the client
also signs another piece of data that is unique to this handshake and known by both the client
and server. In this case the client sends both the signed data and the client’s own certificate to
the server along with the encrypted premaster secret.
6. If the server has requested client authentication, the server attempts to authenticate the client.
If the client cannot be authenticated, the session is terminated. if the client can be successfully
authenticated, the server uses its private key to decrypt the premaster secret, then performs a
series of steps (which the client also performs, starting from the same premaster secret) to
generate the master secret.
7. Both the client and the server use the master secret to generate the session keys, which are
symmetric keys used to encrypt and decrypt information exchanged during the SSL/TLS
session and to verify its integrity—that is, to detect any changes in the data between the time
it was sent and the time it is received over the SSL connection.
8. The client sends a message to the server informing it that future messages from the client will
be encrypted with the session key. It then sends a separate (encrypted) message indicating
that the client portion of the handshake is finished.
9. The server sends a message to the client informing it that future messages from the server will

Figure 4-11 Typical SSL Handshake Process
The Pro Series can act as a SSL server or as a SSL client depending on status of TCP mode. If TCP
connection with SSL is initiated from remote host first, Pro Series acts as a SSL server during the SSL
handshake process. On the contrary, if TCP connection with SSL is initiated from serial port of Pro
Series first, Pro Series acts as a SSL client during the SSL handshake process.
z Client Authentication by certificate (server mode only)
If user selects Client Authentication by certificate option as “Enable”, Pro Series will request the client’s
certificate while in SSL handshaking process (Step 2). On the contrary, if user selects Client
Authentication by certificate option as “Disable”, Pro Series does not request the client’s certificate
while in SSL handshaking process (Step 2).

4.2.6. Serial port parameters
To connect the serial device to the Pro Series serial port, the serial port parameters of the Pro Series
should match exactly to that of the serial device attached. The serial port parameters are required to
match this serial communication. The parameters required for the serial communication are: UART
type, baud rate, data bits, parity, stop bits, flow control DTR/DSR behavior and inter-character timeout.
z Baud rate
The valid baud rate for the Pro Series is as follows:
75, 150, 200, 300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 38400, 57600, 115200, and
230400
The factory default setting is 9600.
z Data bits
Data bits can be between 7 bits and 8 bits. The factory default setting is 8 bits.

z Parity
Parity can be none, even or odd. The factory default setting is none.
z Stop bits
Stop bits can be between 1 bit and 2 bits. The factory default setting is 1 bit.
Figure 4-14 Serial parameter configuration
z Flow control
The factory default setting of the flow control is None. Software Flow Control using XON/XOFF
and hardware flow control using RTS/CTS are supported by the Pro Series.
Software flow control method controls data communication flow by sending special characters
XON/XOFF (0x11/0x13) between two connected devices. And hardware flow control method
controls data communication flow by sending signals back and forth between two connected
devices.
Note:
Flow control is supported only in RS232 and RS422 mode. RS485 mode does not support any
kind of flow control method.
z DTR/DSR behavior
Purpose of the DTR/DSR pin is to emulate modem signal control or to control TCP connection
state by using serial port signal. The DTR is a write-only output signal, whereas the DSR is a
read-only input signal in the Pro Series.
삭제됨:
삭제됨:
삭제됨:
삭제됨:
삭제됨:
65
The DTR option can be set to one of three types: always high, always low or high when TCP/UDP
is opened. If the DTR behavior is set to high when TCP/UDP is opened, the state of the DTR pin
will be maintained high if the TCP/UDP connection is established.
The DSR input behavior can be set to one of two types: none or allow TCP/UDP connection only
by high. If user sets the DSR input behavior as Allow TCP/UDP connection only by HIGH, TCP
connection to remote host from Pro Series is made only when the DSR status is changed from
low to high. And TCP connection to remote host is disconnected when the DSR status is changed
from high to low. And also Pro Series accepts TCP connection from the remote host only when
the DSR status is high. In case of UDP mode, Pro Series receives UDP data from the remote host
only when the DSR status is high. But In modem emulation mode, the connection to the remote
host will be disconnected when the DSR status is changed from high to low regardless of the
value of DSR behavior.
Serial device connected to Pro Series can control TCP/UDP connection of Pro Series by
controlling DTR signal of it.
Note:
1. DTR/DSR behavior configuration will not be effective when the modem is enabled.
2. DTR/DSR behavior does not effective in RS422 and RS485 mode.
z Inter-character timeout
This parameter defines the interval the Pro Series fetches the overall serial data from its internal
buffer. If there is an incoming data through the serial port, the Pro Series stores data into the
internal buffer. The Pro Series transfers data stored in the buffer via TCP/IP, only if the internal
buffer is full or if the inter-character time interval reaches the time specified in the inter-character
timeout setting. If inter-character timeout is set as 0, then data stored in the internal buffer will be
transferred immediately without any delay.
Optimal inter-character timeout would be different according to your application but at least it must
be larger than one character interval within specified baud rate. For example, assume that the
serial port is set to 1200 bps, 8 Data bits, 1 stop bit, and no parity. In this case, the total number of
bits to send a character is 10 bits and the time required to transfer one character is
10 (bits) / 1200 (bits/s) * 1000 (ms/s) = 8.3 ms.
Therefore, you have to set inter-character timeout to be larger than 8.3 ms. The inter-character
timeout is specified in milliseconds.
4.2.7. Modem configuration
The Pro Series supports direct modem connection to the serial port. When user wants to connect to a
modem on its serial port, he must configure Modem init-string and DCD behavior on the modem

configuration page. The Pro Series supports modem connection only when host mode is set as TCP
mode.
z Enable/Disable modem
By enabling this menu, user can attach a modem directly to the serial port of Pro Series. If this
parameter is enabled, Pro Series considers this port will be used for modem use exclusively.
z Modem init-string
User can specify modem initialization string for his modem in Modem init-string parameter. When
a serial port is set to modem mode by setting Enable/Disable modem parameter as Enabled, Pro
Series sends modem initialization string to the serial port whenever rising edge of DTR pin is
detected or parameter related with serial port configuration is changed.
z DCD behavior
If DCD behavior is set as Allow TCP connection only by HIGH, Pro Series permits a connection
from the remote host only when the DCD status of serial port is high. This feature is useful when
user want to use a serial port only for dial-in modem mode. In this case, if there is no connection
through modem already, Pro Series will not permit a TCP side connection.
z Automatic release modem connection
If Automatic release modem connection is set as Enable, modem connection will be closed by Pro
Series if all TCP connections are closed. If this option is set as Disable, modem connection will
not be closed by Pro Series even if all TCP connections are closed. Please note that actual phone
line connection will be closed if one of modems closes connection. That is, this option can be
used for Pro Series to allow disconnection of a modem connection by itself when all TCP
connections are closed.
If user wants to use dial-out function, he should set DCD behavior as None because he must be able
to access modem connected to a serial port to send dial out command to the modem first.

4.2.8. Port Logging
With the port logging feature, the data sent through the serial port is stored to MEMORY or a mounting
point on an NFS server.
z Enable/disable port logging
This parameter defines whether to enable or disable the port-logging feature. The factory default
setting is [disabled].
z Port log storage location
The port log data can be stored to the Pro Series’ internal memory or the mounting point on an
NFS server. If the internal memory is used to store port log data, the port log data will be cleared
when the Pro Series is turned off. To preserve the serial port log data, set the storage location to
be the NFS server. To do this, the user must configure the NFS server in advance. Please refer to

the section 3.9 NFS server configuration for details of NFS server configuration.
z Port log buffer size
This parameter defines the maximum amount of port log data to be logged. When using internal
memory to store the log data, the total size of the port buffer cannot exceed 10 Kbytes.
When using an NFS server to store log data, the maximum port buffer size is unlimited. The user
should configure the NFS server to ensure that the port logging system works properly.
Figure 4-16 Port logging configuration
4.2.9. Port event handling configurations
The Pro Series provides a user for a means of monitoring or reacting to data from serial device
attached to a serial port of it through Port event handling configuration. Namely, user can define
keywords for each serial port that will trigger the email/SNMP notification or command sent to the
serial port directly on Port event handling configuration. This will enable the user to monitor the data
from the attached device or to manage/control a device attached serial port directly when pre-defined
keywords are detected. Also, the status of the connection between the Pro Series and the serial
device and the status of the TCP connection between the Pro Series and remote hosts could be
monitored and managed as well.
Each reaction can be configured individually upon each event. Reaction can be an email delivery,
SNMP trap sending, command sending or either combination of all reactions.
z Port event handling
If the user wants to enable port event handling feature, set Port event handling as enable. This is
a global parameter so if this feature is disabled, the Pro Series does not take any actions on port
events.

z Notification interval
To prevent Pro Series from being trapped in handling port event, there is a Notification interval
parameter. Pro Series will send notification email or SNMP trap every Notification interval even it
detects predefined keyword within Notification interval. The smaller value of this parameter will
result in immediate response for predefined keyword and heavy usage of system resources. The
largest value accepted by user is recommended to prevent system resource usage minimization.
NOTE: The port command in keyword response is not affected by this parameter. Port command
will be sent immediately when the corresponding keyword is detected.
z Email notification
This parameter enables or disables Email notification feature of the Pro Series. When Pro Series
sends Email notification, it uses the SMTP server configured in SMTP server configuration. If the
SMTP server is not configured correctly or disabled, Email feature will be disabled. For details of
SMTP server configurations and descriptions, please refer to section 3.5 SMTP Configuration.
z Subject of Email
This parameter set the subject of Email that will be sent by Pro Series when pre-defined keyword
is detected.
z Recipient’s Email address
This parameter set mail recipient who will receive notification mail when pre-defined keyword is
detected.
z SNMP trap notification
This parameter enables or disables SNMP trap notification feature of Pro Series.
z Subject of SNMP trap
This parameter set the subject of SNMP trap that will be sent by Pro Series when pre-defined
keyword is detected.

Event keywords
The user can assign event keywords so that the Pro Series takes actions such as sending e-mail
notification, sending SNMP trap notification or sending pre-defined command to a serial port if the
keyword is detected at the serial port.
z Event keyword
User can specify any words, which he/she wants to set as a keyword.
z Email notification
User can select enable or disable for the Email notification action on keyword selected.
z SNMP trap notification
User can select enable or disable for the SNMP trap notification action on keyword selected.
z Port command
Pro Series supports direct reaction to a device attached to serial port when pre-defined keyword is
detected. User can specify command or string, which will be sent to a serial port on this menu.
4.2.10. Copy port configuration
User can copy port configuration of one port to another. There are two methods in copying port
configuration. One is “Copy current port configuration to” specified ports and another is “Copy current
port configuration from” specified port.
NOTE:
Port title, TCP port number and UDP port number are not copied by this function.

5. System Administration
The Pro Series displays the system status and the log data via a Status Display Screen. This screen is
used for management purposes. System status data includes the model name, serial number,
firmware version and the network configuration of the Pro Series. The Pro Series can also be
configured to deliver log data automatically via email to a specified recipient with the system-logging
feature.
The users can configure the Pro Series’ device name, date and time settings, and reload factory
default settings in this menu group. The users can also upgrade the firmware of the Pro Series using
the web interface, remote consoles or serial console.
5.1. System Status
Figure 5-1 System status display
5.2. System Logging
The Pro Series provides both the system logging feature and the system log status display. The user
may configure the Pro Series to enable or disable the system logging process, the system log buffer
size, as well as select the log storage location.
z System log storage location
The system log can be stored in the Pro Series internal memory, the mounting point on an

NFS server or the SYSLOG server. If the internal memory is used to store system log data, the
log data will be cleared when the Pro Series is turned off. To preserve the system log data, set
the storage location to be SYSLOG server or NFS server. To do this, the user must configure the
corresponding media in advance. Unless the media is properly set up, the log will not be written to
a specified storage location properly.
The Pro Series can also be configured to send log data automatically if the number of logs unsent
reaches a pre-defined number. If enabled, the user must set parameters to initiate the creation of a
email. These parameters would include the number of logs required to trigger an email, the recipient’s
email address, etc. Figure 5-2 shows the configuration and system log view screen.
Figure 5-2 System log configuration and view
5.3. Change Password
The password for the administrative system user (root) of Pro Series can be changed using this menu.

configuration screen. When user changes Device name, hostname of Pro Series will be also changed.
Figure 5-4 Device name configuration
Please note that user cannot set space character as a device name. If user sets blank as Device
name then hostname is set as IP address of Pro Series automatically.
And also the device name is utilized for management program, HelloDevice Manager.
5.5. Date and Time Settings
The Pro Series maintains current date and time information. The PSx10W’s clock and calendar
settings are backed up by internal battery power.
The user can change the current date and time, as shown in Figure 5-5.
Figure 5-5 Date and time configuration
User also uses the NTP (Network Time Protocol) sever for setting the time of the Pro Series as shown
in Figure 5-6. If the NTP feature is enabled, the Pro Series will obtain the date and time information
from the NTP server at each reboot. If the NTP server is set to 0.0.0.0, the Pro Series will use the
default NTP servers. In this case, the Pro Series should be connected from the network to the Internet.
The user may also need to set the time offset from UTC depending on the users’ location.

6.3. IP Statistics
The IP Statistics screen provides statistical information about packets/connections using an IP
protocol. Definitions and descriptions of each parameter are described below:
Forwarding :
Specifies whether IP forwarding is enabled or disabled.
DefaultTTL :
Specifies the default initial time to live (TTL) for datagrams originating on a particular computer.
InReceives :
Shows the number of datagrams received.
InHdrErrors :
Shows the number of datagrams received that have header errors. Datagrams Received Header
Errors is the number of input datagrams discarded due to errors in their IP headers, including bad
checksums, version number mismatch, other format errors, time-to-live exceeded, errors
discovered in processing their IP options, etc.
InAddrErrors :
Specifies the number of datagrams received that have address errors. These datagrams are
discarded because the IP address in their IP header’s destination field was not a valid address to
be received at this entity. This count includes invalid addresses (for example, 0.0.0.0) and
addresses of unsupported Classes (for example, Class E).
ForwDatagrams :
Specifies the number of datagrams forwarded.
InUnknownProtos :
Specifies the number of locally addressed datagrams received successfully but discarded
because of an unknown or unsupported protocol.
InDiscard :
Specifies the number of input IP datagrams for which no problems were encountered to prevent
their continued processing, but which were discarded (for example, for lack of buffer space). This
삭제됨:

84
counter does not include any datagrams discarded while awaiting reassembly.
InDelivers :
Specifies the number of received datagrams delivered.
OutRequests :
Specifies the number of outgoing datagrams that an IP is requested to transmit. This number
does not include forwarded datagrams.
OutDiscards :
Specifies the number of transmitted datagrams discarded. These are datagrams for which no
problems were encountered to prevent their transmission to their destination, but which were
discarded (for example, for lack of buffer space.) This counter would include datagrams counted
in Datagrams Forwarded if any such packets met this (discretionary) discard criterion.
OutNoRoutes :
Specifies the number of datagrams for which no route could be found to transmit them to the
destination IP address. These datagrams were discarded. This counter includes any packets
counted in Datagrams Forwarded that meet this “no route” criterion.
ReasmTimeout :
Specifies the amount of time allowed for all pieces of a fragmented datagram to arrive. If all
pieces do not arrive within this time, the datagram is discarded.
ReasmReqds :
Specifies the number of datagrams that require reassembly.
ReasmOKs :
Specifies the number of datagrams that were successfully reassembled.
ReasmFails :
Specifies the number of datagrams that cannot be reassembled.
FragOKs :
Specifies the number of datagrams that were fragmented successfully.
FragFails :
Specifies the number of datagrams that need to be fragmented but couldn’t be because the IP
header specifies no fragmentation. For example, if the datagrams “Don’t Fragment” flag was set,
the datagram would not be fragmented. These datagrams are discarded.
FragCreates :
Specifies the number of fragments created.

7. CLI guide
7.1. Introduction
The root user can access the Linux console command line interface (CLI) of the Pro Series via the
serial console or TELENT/SSH. In the CLI, the user can perform standard Linux commands to view
the status of the Pro Series, edit the configuration, apply configuration changes.
7.2. Flash partition
The Pro Series internal flash is partitioned as shown in the table below. The user can access files at
/var directory at his own risk. Simply accessing these files will not affect the Pro Series after
rebooting. However, if the user invokes the command saveconf, the changes in the configuration file
will be committed to the internal flash memory area of the Pro Series. This will result in the changes
being kept after the reboot sequence. Invalid configuration changes can affect the Pro Series behavior.
At worst, it may cause the Pro Series to become inoperable.

A 4.4. Hardware test menu
Using the Hardware test menu, the user can test hardware components. There are three hardware
test modes:
- One time
- Looping (without External test in Auto test)
- Looping (with External test in Auto test)
If the user selects One time, an auto test or each component test is performed just once. In this mode,
the ping test to the remote host (server IP address) and UART test are also performed once.
If the user selects Looping (without External test in Auto test), the auto test is performed repeatedly
until the user presses the <ctrl-c> keys. In this mode, the ping test to the remote host (server IP
address) and UART test are not performed.
If the user selects Looping (with External test in Auto test)’, auto test is performed repeatedly until the
user presses the <ctrl-c> keys. And, the ping test to the remote host (server IP address) and UART
test are also performed repeatedly.
Note:
To perform the test on the Ethernet and UART properly, the user must connect an Ethernet cable to
