To have each log in the BHM correlated to a meaningful time and date, either a reliable
network element must pass time and date to the BHM or you must set the time and date
whenever a power cycle of the BHM has occurred. A network element passes time and
date in any of the following scenarios:
◦ A connected CMM2 passes time and date (GPS time and date, if received).
◦ A connected CMMmicro passes the time and date (GPS time and date, if
received), but only if the CMMmicro is operating on CMMmicro Release 2.1 or
later release. (These releases include an NTP server functionality.)
◦ A separate NTP server is addressable from the BHM.
If the BHM should derive time and date from either a CMMmicro or a separate NTP
server, enter the IP address of the CMMmicro or NTP server on this tab. To force the

the BHS, its module type, and its MAC address.
Software Version
This field indicates the Canopy system release, the time and date of the release, the
modulation rate, and whether communications involving the module are secured by DES
or AES encryption (see Encrypting Canopy Radio Transmissions on Page 371). If you
request technical support, provide the information from this field.
Release 8 Installation and Configuration Guide
Issue 2, December 2006 Draft 2 for Regulatory Review 211
Software BOOT Version
This field indicates the version of the CANOPYBOOT file. If you request technical
support, provide the information from this field.
Board Type
This field indicates the series of hardware. See Designations for Hardware in Radios on
Page 367.
FPGA Version
This field indicates the version of the field-programmable gate array (FPGA) on the
module. When you request technical support, provide the information from this field.
Uptime
This field indicates how long the module has operated since power was applied.
System Time
This field provides the current time. When a BHS registers to a BHM, it inherits the
system time, which is displayed in this field as GMT (Greenwich Mean Time).
Ethernet Interface
This field indicates the speed and duplex state of the Ethernet interface to the BHS.
Session Status
This field displays the following information about the current session:
◦ Scanning indicates that this SM currently cycles through the RF frequencies that
are selected in the Radio tab of the Configuration page.
◦ Syncing indicates that this SM currently attempts to receive sync.
◦ Registering indicates that this SM has sent a registration request message to
the AP and has not yet received a response.
◦ Registered indicates that this SM is both
− registered to an AP.
− ready to transmit and receive data packets.
◦ Alignment indicates that this SM is in an aiming mode. See Table 45 on
Page 179.
Registered AP
This field displays the MAC address of the BHM to which this BHS is registered.
RSSI, Power Level, and Jitter
The General Status tab shows the received Power Level in dBm and Jitter. Proper
alignment maximizes Power Level and minimizes Jitter. As you refine alignment, you
should favor lower jitter over higher dBm. For example, if coarse alignment gives the BHS
a power level of −75 dBm and a jitter measurement of 5, and further refining
the alignment drops the power level to −78 dBm and the jitter to 2 or 3, use the refined
alignment, with the following caveats:
◦ When the receiving link is operating at 1X, the Jitter scale is 0 to 15 with desired
jitter between 0 and 4.
Installation and Configuration Guide Release 8
212 Draft 2 for Regulatory Review Issue 2, December 2006
◦ When the receiving link is operating at 2X, the Jitter scale is 0 to 15 with desired
jitter between 0 and 9.
For historical relevance, the General Status tab also shows the RSSI, the unitless
measure of power. Use Power Level and ignore RSSI. RSSI implies more accuracy and
precision than is inherent in its measurement.
NOTE:
Unless the page is set to auto-refresh, the values displayed are from the instant
the General Status tab was selected. To keep a current view of the values,
refresh the browser screen or set to auto-refresh.
Air Delay
This field displays the distance in feet between the BHS and the BHM. To derive the
distance in meters, multiply the value of this parameter by 0.3048. Distances reported as
less than 200 feet (61 meters) are unreliable.
Site Name
This field indicates the name of the physical module. You can assign or change this
name in the SNMP tab of the BHS Configuration page. This information is also set into
the sysName SNMP MIB-II object and can be polled by an SNMP management server.
Site Contact
This field indicates contact information for the physical module. You can provide or
change this information in the SNMP tab of the BHS Configuration page. This information
is also set into the sysName SNMP MIB-II object and can be polled by an SNMP

CAUTION!
Never connect any devices other than Canopy APs and BHs to a powered port.
Powered ports are indicated by a red LED to the right of the port. (See Item 7 in
Figure 75 on Page 220.) A powered port has
24-V DC on Pins 7 and 8 and 24-V return on Pins 4 and 5. This can damage
other networking equipment, such as a computer or a router.
If you change this value for a port and then click Save Changes, then the change
becomes effective immediately and the previous value is lost.
Display-Only Access
To set this password, enter the same expression in both Display-Only Access fields for
verification. When the web-based interface prompts for this password, no user name is
required. However, when a telnet or FTP session prompts for this password, you must
enter the user name root in addition to the password.
If you set and then forget the Display-Only Access password, then you must both
1. physically access the module.
2. use the CMMmicro override toggle switch to electronically access the module
configuration parameters at 169.254.1.1. See Overriding Forgotten IP Addresses
or Passwords on CMMmicro on Page 377.
Full Access
If you set the Full Access password, this password will allow
◦ telnet and FTP access to the module.
◦ viewing or changing the parameters of the module.
To set this password, enter the same expression in both Full Access fields for
verification. When the web-based interface prompts for this password, no user name is
required. However, when a telnet or FTP session prompts for this password, you must
enter the user name root in addition to the password.
If you set and then forget the Full Access password, then you must both
1. physically access the module.
2. use the CMMmicro override toggle switch to electronically access the module
configuration parameters at 169.254.1.1. See Overriding Forgotten IP Addresses
or Passwords on CMMmicro on Page 377.
NOTE:
You can unset either password (revert the access to no password required). To
do so, type a space into the field and reboot the module. You must enter any
password twice to allow the system to verify that the password is not mistyped.
After any password is set and a reboot of the module has occurred, a Password
Set indicator appears to the right of the field.

passwords both with the module and with the other data that you store about the
module.
Webpage Auto Update
Enter the frequency (in seconds) for the web browser to automatically refresh the web-
based interface. The default setting is 0. The 0 setting causes the web-based interface to
never be automatically refreshed.
If you change this value and then click Save Changes, then the change becomes
effective immediately and the previous value is lost.
SNMP Community String
Specify a control string that allows an Network Management Station (NMS) to access
SNMP information. No spaces are allowed in this string. The default string is Canopy.
The SNMP Community String value is clear text and is readable by a packet monitor.
Additional security derives from the configuration of the SNMP Accessing Subnet,
Trap Address, and Permission parameters.
SNMP Accessing Subnet
Specify the addresses that are allowed to send SNMP requests to this CMMmicro. The
NMS has an address that is among these addresses (this subnet). You must enter both
◦ The network IP address in the form xxx.xxx.xxx.xxx
◦ The CIDR (Classless Interdomain Routing) prefix length in the form /xx
For example
◦ the /16 in 198.32.0.0/16 specifies a subnet mask of 255.255.0.0 (the first 16 bits
in the address range are identical among all members of the subnet).
◦ 192.168.102.0 specifies that any device whose IP address is in the range
192.168.102.0 to 192.168.102.254 can send SNMP requests to the CMMmicro,
presuming that the device supplies the correct SNMP Community String value.
RECOMMENDATION:
For more information on CIDR, execute an Internet search on “Classless
Interdomain Routing.”
The default treatment is to allow all networks access.
Release 8 Installation and Configuration Guide
Issue 2, December 2006 Draft 2 for Regulatory Review 229
Trap Address
Specify the IP address (xxx.xxx.xxx.xxx) of one to ten servers (Prizm or NMS) to which
trap information should be sent. Trap information informs the monitoring systems that
something has occurred. For example, trap information is sent
◦ after a reboot of the module.
◦ when Prizm or an NMS attempts to access agent information but either
− supplied an inappropriate community string or SNMP version number.
− is associated with a subnet to which access is disallowed.
Permission
Select Read Only if you wish to disallow any parameter changes by Prizm or an NMS.
Site Name
Specify a string to associate with the physical module. This parameter is written into the
sysName SNMP MIB-II object and can be polled by an NMS. The buffer size for this field
is 128 characters.
Site Contact
Enter contact information for the module administrator. This parameter is written into the
sysContact SNMP MIB-II object and can be polled by an NMS. The buffer size for this
field is 128 characters.
Site Location
Enter information about the physical location of the module. This parameter is written into
the sysLocation SNMP MIB-II object and can be polled by an NMS. The buffer size for
this field is 128 characters.
The CMMmicro Configuration page also provides the following buttons.
Enable 802.1Q Tagging
Once 802.1Q Tagging is enabled and an 802.1Q VLAN ID is set, only frames that are
VLAN tagged with the configured tag value will be accepted by the management
controller of the CMMmicro. All frames outgoing from the management controller of the
CMMmicro will have an 802.1Q VLAN tag, set to the configured VLAN ID.
802.1Q VLAN ID
Once 802.1Q Tagging is enabled and an 802.1Q VLAN ID is set, only frames that are
VLAN tagged with the configured tag value will be accepted by the management
controller of the CMMmicro. All frames outgoing from the management controller of the
CMMmicro will have an 802.1Q VLAN tag, set to the configured VLAN ID.
VLAN Port Configuration
Each column in the VLAN Port Configuration section of Figure 78 corresponds to a port.
Checkboxes in each column control which ports can transmit traffic that arrives on the
(column) port. For example, in the first column if only Port 2 is checked, then Port 1
(column 1) will only be allowed to send data out on Port 2 (checked box). Port 2 (second
column) is able to send data out on all other ports. All other ports, meanwhile, are only
allowed to send data out on Port 2. This configuration is also known as an Uplink
configuration for Port 2.
Each direction (for example, port 1 to port 2 versus port 2 to port 1) must be configured
separately. It is possible to configure a port to send data to a second port, but not allow
Installation and Configuration Guide Release 8
230 Draft 2 for Regulatory Review Issue 2, December 2006
the second port to send data back to the first port (for example, check Port 8 in the Port 2
column, but do not check Port 2 in the Port 8 column). These settings should be changed
with caution, and with two-way communication in mind.
In all cases, even when not checked, all ports will still be able to communicate with the
CMMmicro management controller.
Setting (checking) any Uplink Port checkboxes (see Figure 78) will override VLAN Port
Configuration settings. If you desire complete control on a port-by-port basis using VLAN
Port Configuration, all Uplink Port boxes must be unchecked in the Uplink Port section.

16.4.10 Configuring Modules for Connection to CMMmicro
After configuring the CMMmicro, configure the APs and BHs as follows. In each AP or BH
that connects to a CMMmicro, you must set the Sync Input parameter of the
Configuration page of that module to Sync to Received Signal (Power Port).
See
◦ Sync Input on Page 237.
◦ Sync Input on Page 296.
16.4.11 Event Log Page of the CMMmicro

technical support. For this reason, the operator should not clear the contents of this page
before contacting technical support.
16.4.12 GPS Status Page of the CMMmicro
An example of the CMMmicro GPS Status page is displayed in Figure 79.
Figure 79: GPS Status page of CMMmicro, example
The GPS Status page provides information from the GPS antenna and information about
the GPS receiver in the CMMmicro.

This field displays information about the GPS interface board.
16.4.13 Port MIB Page of the CMMmicro
An example of the Port MIB (Ethernet statistics) web page is displayed in Figure 80.
Figure 80: Port MIB page of CMMmicro, example
The Port MIB page displays Ethernet statistics and traffic information for the ports on the
managed switch. To display the port statistics, click on a port number.
Ports 1 through 8 are the regular ports, connected to APs, BHs, or other network
elements. Port 9 is the connection between the managed switch and the CMMmicro
processor. Thus, updates to interface pages, SNMP activities, and FTP and telnet
sessions create traffic on Port 9.
These Ethernet statistics can also be retrieved from the CMMmicro by a Network
Management Station using SNMP. During advanced troubleshooting, this information can
be useful as you see the activity on a single port or as you compare activity between
ports of the CMMmicro.

17 PREPARING COMPONENTS FOR DEPLOYMENT
Your test of the modules not only verified that they are functional, but also yielded data
that you have stored about them. Most efficiently preparing modules for deployment
involves
◦ retrieving that data.
◦ systematically collecting the data into a single repository, while keeping a strong
(quick) association between the data and the module.
◦ immediately merging module access data into this previously stored data.
17.1 CORRELATING COMPONENT-SPECIFIC INFORMATION
You can use the data that you noted or printed from the Status pages of the modules to
◦ store modules for future deployment.
◦ know, at a glance, how well-stocked you are for upcoming network expansions.
◦ efficiently draw modules from stock for deployment.
◦ plan any software updates that you
− wish to perform to acquire features.
− need to perform to have the feature set be consistent among all modules in a
network expansion.
You can make these tasks even easier by collecting this data into a sortable database.
17.2 ENSURING CONTINUING ACCESS TO THE MODULES
As you proceed through the steps under Configuring for the Destination on Page 235,
you will set values for parameters that specify the sync source, data handling
characteristics, security measures, management authorities, and other variables for the
modules. While setting these, you will also tighten access to the module, specifically in
◦ the Color Code parameter of Configuration page
◦ the Display-Only Access and Full Access password parameters of the
Configuration page.
◦ the addressing parameters of the IP Configuration page.
Before you set these, consider whether and how you may want to set these by a self-
devised scheme. A password scheme can help you when you have forgotten or misfiled
a password. An IP addressing scheme may be essential to the operation of your network
and to future expansions of your network.
As you set these, note the color code and note or print the parameters you set on the
Configuration page tabs. Immediately associate them with the following previously stored
data about the modules:
◦ device type, frequency band, and MAC address
◦ software version and encryption type
◦ software boot version
◦ FPGA version

The General tab of the AP contains many of the configurable parameters that define how
the AP and the SMs in the sector operate. As shown in Figure 81, you may set the
Configuration page parameters as follows.
Release 8 Installation and Configuration Guide
Issue 2, December 2006 Draft 2 for Regulatory Review 237
Device Setting
You can temporarily transform an AP into an SM and thereby use the spectrum analyzer
functionality. See Using the AP as a Spectrum Analyzer on Page 366. Otherwise, the
selection for this parameter is AP.
Link Speeds
Specify the type of link speed for the Ethernet connection. The default for this parameter
is that all speeds are selected. The recommended setting is a single speed selection for
all APs, BHs, and SMs in the operator network.
Configuration Source
See Setting the Configuration Source on Page 292.
CAUTION!
Do not set this parameter to BAM where both
◦ a BAM release earlier than 2.1 is implemented.
◦ the All Local SM Management parameter (in the VLAN Configuration
page of the AP) is set to Enable.
This combination causes the SMs to become unmanageable, until you gain
direct access with an Override Plug and remove this combination from the AP
configuration.
Sync Input
Specify the type of synchronization for this AP to use:
◦ Select Sync to Received Signal (Power Port) to set this AP to receive sync
from a connected CMMmicro.
◦ Select Sync to Received Signal (Timing Port) to set this AP to receive sync
from a connected CMM2, an AP in the cluster, an SM, or a BH timing slave.
◦ Select Generate Sync Signal where the AP does not receive sync, and no other
AP or BHM is active within the link range.
Webpage Auto Update
Enter the frequency (in seconds) for the web browser to automatically refresh the web-
based interface. The default setting is 0. The 0 setting causes the web-based interface to
never be automatically refreshed.
Bridge Entry Timeout
Specify the appropriate bridge timeout for correct network operation with the existing
network infrastructure. The Bridge Entry Timeout should be a longer period than the ARP
(Address Resolution Protocol) cache timeout of the router that feeds the network.
Installation and Configuration Guide Release 8
238 Draft 2 for Regulatory Review Issue 2, December 2006
CAUTION!
An inappropriately low Bridge Entry Timeout setting may lead to temporary loss
of communication with some end users.
Translation Bridging
If you want the Translation Bridging feature, select Enabled. This has numerous
implications. For a full description of them, see Uplink Frame Contents on Page 83.
Send Untranslated ARP
If the Translation Bridging parameter is set to Enabled, then the Send Untranslated
ARP parameter can be
◦ disabled, so that the AP will overwrite the MAC address in Address Resolution
Protocol (ARP) packets before forwarding them.
◦ enabled, so that the AP will forward ARP packets regardless of whether it has
overwritten the MAC address.
See Uplink Frame Contents on Page 83 and Address Resolution Protocol on Page 162.
If the Translation Bridging parameter is set to Disabled, then the Send Untranslated
ARP parameter has no effect.
SM Isolation
Prevent or allow SM-to-SM communication by selecting from the following drop-down
menu items:
◦ Disable SM Isolation (the default selection). This allows full communication
between SMs.
◦ Block SM Packets from being forwarded. This prevents both
multicast/broadcast and unicast SM-to-SM communication.
◦ Block and Forward SM Packets to Backbone. This not only prevents
multicast/broadcast and unicast SM-to-SM communication but also sends the
packets, which otherwise would have been handled SM to SM, through the
Ethernet port of the AP.
Update Application Address
Enter the address of the server to access for software updates on this AP and registered
SMs.
2X Rate
See 2X Operation on Page 91.
Prioritize TCP ACK
To reduce the likelihood of TCP acknowledgement packets being dropped, set this
parameter to Enabled. This can improve throughput that the end user perceives during
transient periods of congestion on the link that is carrying acknowledgements. See AP-
SM Links on Page 99.
The General tab also provides the following buttons.

An example of the IP tab of the AP is displayed in Figure 82.
Figure 82: IP tab of AP, example
Installation and Configuration Guide Release 8
240 Draft 2 for Regulatory Review Issue 2, December 2006
You may set the IP tab parameters as follows.
LAN1 Network Interface Configuration, IP Address
Enter the non-routable IP address to associate with the Ethernet connection on this AP.
(The default IP address from the factory is 169.254.1.1.) If you set and then forget this
parameter, then you must both
1. physically access the module.
2. use an override plug to electronically access the module configuration
parameters at 169.254.1.1. See Overriding Forgotten IP Addresses or
Passwords on AP, SM, or BH on Page 377.
RECOMMENDATION:
Note or print the IP settings from this page. Ensure that you can readily
associate these IP settings both with the module and with the other data that you
store about the module.
LAN1 Network Interface Configuration, Subnet Mask
Enter an appropriate subnet mask for the AP to communicate on the network. The default
subnet mask is 255.255.0.0. See Allocating Subnets on Page 162.
LAN1 Network Interface Configuration, Gateway IP Address
Enter the appropriate gateway for the AP to communicate with the network. The default
gateway is 169.254.0.0.
The values of these four LAN1 network interface configuration parameters are displayed
read only along with the Ethernet speed and duplex state on the Network Interface tab of
the Home page in the AP.
LAN1 Network Interface Configuration, DHCP State
If you select Enabled, the DHCP server automatically assigns the IP configuration
(IP address, subnet mask, and gateway IP address) and the values of those individual
parameters (above) are not used. The setting of this DHCP state parameter is also
viewable, but not settable, in the Network Interface tab of the Home page.
LAN2 Network Interface Configuration (RF Private Interface), IP Address
You should not change this parameter from the default AP private IP address of
192.168.101.1. A /24 CIDR subnet is used to communicate with each of the SMs that are
registered. The AP uses a combination of the private IP and the LUID (logical unit ID) of
the SM.
For example, if an SM is the first to register in an AP, and another SM registers later,
then the AP whose Private IP address is 192.168.101.1 uses the following SM Private IP
addresses to communicate to each:
SM
LUID
Private IP
First SM registered
2
192.168.101.2
Second SM registered
3
192.168.101.3
Release 8 Installation and Configuration Guide
Issue 2, December 2006 Draft 2 for Regulatory Review 241
NOTE:
Where space is limited for subnet allocation, be advised that an SM need not
have an operator-assigned IP address. The SM is directly accessible without an
LUID if either the SM Color Code parameter is set to 0 or the AP has a direct
Ethernet connection to the SM.
The IP Configuration page also provides the following buttons.
Save Changes
When you click this button, any changes that you made on this tab are recorded in flash
memory. However, these changes do not apply until the next reboot of the module.
Reboot
When you click this button
1. the module reboots.

18.1.3 Radio Tab of the AP
An example of the Radio tab of the AP is shown in Figure 83.
Figure 83: Radio tab of AP (900 MHz), example
Installation and Configuration Guide Release 8
242 Draft 2 for Regulatory Review Issue 2, December 2006
The Radio tab of the AP contains some of the configurable parameters that define how
the AP operates. As shown in Figure 83, you may set the Radio tab parameters as
follows.
Radio Frequency Carrier
Specify the frequency for the module to transmit. The default for this parameter is None.
(The selection labeled Factory requires a special software key file for implementation.)
For a list of channels in the band, see the drop-down list or Considering Frequency Band
Alternatives on Page 136.
Color Code
Specify a value from 0 to 254. For registration to occur, the color code of the SM and the
AP must match. Color code is not a security feature. Instead, color code is a
management feature, typically for assigning each sector a different color code.
Color code allows you to force an SM to register to only a specific AP, even where the
SM can communicate with multiple APs. On all Canopy modules, the default setting for
the color code value is 0. This value matches only the color code of 0 (not all 255 color
codes).
RECOMMENDATION:
Note the color code that you enter. Ensure that you can readily associate this
color code both with the module and with the other data that you store about the
module.
Sector ID
Specify a number in the range 1 to 6 to associate with this AP. The Sector ID setting
does not affect the operation of the AP. On the AP Evaluation tab of the Tools page in
the SM, the Sector ID field identifies the AP that the SM sees. The following steps may
be useful:
◦ Assign a unique Sector ID to each sector in an AP cluster.
◦ Repeat the assignment pattern throughout the entire Canopy system.
Max Range
Enter a number of miles (or kilometers divided by 1.61, then rounded to an integer) for
the furthest distance from which an SM is allowed to register to this AP. Do not set the
distance to any greater number of miles. A greater distance
◦ does not increase the power of transmission from the AP.
◦ can reduce aggregate throughput. See Table 27 on Page 100.
Regardless of this distance, the SM must meet the minimum requirements for an
acceptable link. If the AP is in cluster, then you must set this parameter on all other APs
in the cluster exactly the same, except as described in the NOTE admonition below.
The default value of this parameter is 2 miles (3.2 km).
For APs in the non 900-MHz frequency band ranges, although the typical maximum
range where an SM is deployed with a reflector is 15 miles (24 km), you can set this
parameter to as far as 30 miles (48 km). Without increasing the power or sensitivity of the
Release 8 Installation and Configuration Guide
Issue 2, December 2006 Draft 2 for Regulatory Review 243
AP or SM, the greater value allows you to attempt greater distance where the RF
environment and Fresnel zone6 are especially clear.
A value of 15 for this parameter decreases the number of available data slots by 1.
With a higher value, the number is further decreased as the AP compensates for the
expected additional air delay.
NOTE:
In a cluster where at least one AP has Scheduling set to Software and at least
one to Hardware, you must use the Frame Calculator web page to coordinate
the transmit and receive times and you may further need to adjust the value of
the Max Range parameter for individual APs in the cluster to avoid self
interference. See Using the Frame Calculator Tool (All) on Page 440.
Downlink Data
Specify the percentage of the aggregate throughput for the downlink (frames transmitted
from the AP to the subscriber). For example, if the aggregate (uplink and downlink total)
throughput on the AP is 6 Mb, then 75% specified for this parameter allocates 4.5 Mb for
the downlink and 1.5 Mb for the uplink. The default for this parameter is 75%.
CAUTION!
You must set this parameter exactly the same for all APs in a cluster.
Control Slots
The recommended number of control slots is as stated in Table 48.
Table 48: Control slot settings for all APs in cluster

Register to the AP
Number of Control
Slots Recommended
1 to 10

scheduler uses unreserved slots first, then any unused slots are available with any
reserved slots to the SMs for service requests.

If too few reserved control slots are specified, then latency increases in high traffic
periods. If too many are specified, then the maximum capacity is unnecessarily reduced.
External Filters Delay
This parameter is present in only 900-MHz modules and can have effect in only those
that have interference mitigation filter(s). Leave this value set to 0, regardless of whether
the AP has an interference mitigation filter.
Transmit Frame Spreading
Where multiple AP clusters operate in the same frequency band range and same
geographical area, select Enable. Then SMs between two APs can register in the
assigned AP (do not register in another AP).
Where multiple AP clusters do not operate in the same frequency band range and same
geographical area, select Disable, but observe the following caveat.
IMPORTANT!
SM throughput is 10% greater with this feature disabled. However, if you disable
Transmit Frame Spreading where this feature was previously enabled, monitor
the zone for interference over a period of days to ensure that this action has not
made any SMs sensitive to the wrong beacon.
With this selection enabled, the AP does not transmit a beacon in each frame, but rather
transmits a beacon in only pseudo-random frames in which the SM expects the beacon.
This allows multiple APs to send beacons to multiple SMs in the same range without
interference.
Transmitter Output Power
Nations and regions may regulate transmitter output power. For example
◦ Both 900-MHz and 5.7-GHz modules are available as connectorized radios,
which require the operator to adjust power to ensure regulatory compliance. In
addition to setting the power in the 5.7-GHz connectorized module, the operator
must set the antenna gain/cable loss such that the module can accurately report
received power at the antenna.
◦ Legal maximum allowable transmitter output power and EIRP (Equivalent
Isotropic Radiated Power) in the 2.4-GHz frequency band varies by country and
region. The output power of Series P9 2.4-GHz modules can be adjusted to meet
these national or regional regulatory requirements.
◦ Countries and regions that permit the use of the 5.4-GHz frequency band (CEPT
member states, for example), generally require equipment using the band to
have adjustable power.
The professional installer of Canopy equipment has the responsibility to
◦ maintain awareness of applicable regulations.
◦ calculate the permissible transmitter output power for the module.
◦ confirm that the initial power setting is compliant with national or regional
regulations.
Release 8 Installation and Configuration Guide
Issue 2, December 2006 Draft 2 for Regulatory Review 245
◦ confirm that the power setting is compliant following any reset of the module to
factory defaults.
For information on how to calculate the permissible transmitter output power to enter in
this parameter, see Adjusting Transmitter Output Power on Page 326.

18.1.4 SNMP Tab of the AP
An example of the SNMP tab of the AP is displayed in Figure 84.
Figure 84: SNMP tab of AP, example
Release 8 Installation and Configuration Guide
Issue 2, December 2006 Draft 2 for Regulatory Review 247
You may set the SNMP tab parameters as follows.
Community String
Specify a control string that allows an Network Management Station (NMS) to access
SNMP information. No spaces are allowed in this string. The default string is Canopy.
The Community String value is clear text and is readable by a packet monitor.
Additional security derives from the configuration of the Accessing Subnet, Trap
Address, and Permission parameters.
Accessing Subnet
Specify the addresses that are allowed to send SNMP requests to this AP. The NMS has
an address that is among these addresses (this subnet). You must enter both
◦ The network IP address in the form xxx.xxx.xxx.xxx
◦ The CIDR (Classless Interdomain Routing) prefix length in the form /xx
For example
◦ the /16 in 198.32.0.0/16 specifies a subnet mask of 255.255.0.0 (the first 16 bits
in the address range are identical among all members of the subnet).
◦ 192.168.102.0 specifies that any device whose IP address is in the range
192.168.102.0 to 192.168.102.254 can send SNMP requests to the AP,
presuming that the device supplies the correct Community String value.
The default treatment is to allow all networks access. For more information on CIDR,
execute an Internet search on “Classless Interdomain Routing.”
Trap Address 1 to 10
Specify ten or fewer IP addresses (xxx.xxx.xxx.xxx) to which SNMP traps should be sent.
Traps inform Prizm or an NMS that something has occurred. For example, trap
information is sent
◦ after a reboot of the module.
◦ when an NMS attempts to access agent information but either
− supplied an inappropriate community string or SNMP version number.
− is associated with a subnet to which access is disallowed.
Trap Enable, Sync Status
If you want sync status traps (sync lost and sync regained) sent to Prizm or an NMS,
select Enabled. If you want these traps suppressed, select Disabled.
Trap Enable, Session Status
If you want session status traps sent to Prizm or an NMS, select Enabled. For the names
and descriptions of session status traps, see Traps Provided in the Canopy Enterprise
MIB on Page 406. If you want these traps suppressed, select Disabled.
Read Permissions
Select Read Only if you wish to disallow any parameter changes through SNMP
(for example, from Prizm or an NMS).
Installation and Configuration Guide Release 8
248 Draft 2 for Regulatory Review Issue 2, December 2006
Site Name
Specify a string to associate with the physical module. This parameter is written into the
sysName SNMP MIB-II object and can be polled by PrizmEMS or an NMS. The buffer
size for this field is 128 characters.
Site Contact
Enter contact information for the module administrator. This parameter is written into the
sysContact SNMP MIB-II object and can be polled by PrizmEMS or an NMS. The buffer
size for this field is 128 characters.
Site Location
Enter information about the physical location of the module. This parameter is written into
the sysLocation SNMP MIB-II object and can be polled by PrizmEMS or an NMS. The
buffer size for this field is 128 characters.
The SNMP tab also provides the following buttons.

An example of the Quality of Service (QoS) tab of the AP is displayed in Figure 85.
Figure 85: Quality of Service (QoS) tab of AP, example
In the Quality of Service (QoS) tab, you may set AP bandwidth parameters as follows.
Sustained Uplink Data Rate
Specify the rate that each SM registered to this AP is replenished with credits for
transmission. This default imposes no restriction on the uplink. See
◦ Maximum Information Rate (MIR) Parameters on Page 85
◦ Interaction of Burst Allocation and Sustained Data Rate Settings on Page 88
◦ Setting the Configuration Source on Page 292.
Uplink Burst Allocation
Specify the maximum amount of data to allow each SM to transmit before being
recharged at the Sustained Uplink Data Rate with credits to transmit more. See
◦ Maximum Information Rate (MIR) Parameters on Page 85
◦ Interaction of Burst Allocation and Sustained Data Rate Settings on Page 88
◦ Setting the Configuration Source on Page 292.

250 Draft 2 for Regulatory Review Issue 2, December 2006
Sustained Downlink Data Rate
Specify the rate at which the AP should be replenished with credits (tokens) for
transmission to each of the SMs in its sector. This default imposes no restriction on the
uplink. See
◦ Maximum Information Rate (MIR) Parameters on Page 85
◦ Interaction of Burst Allocation and Sustained Data Rate Settings on Page 88
◦ Setting the Configuration Source on Page 292.
Downlink Burst Allocation
Specify the maximum amount of data to allow the AP to transmit to any registered SM
before the AP is replenished with transmission credits at the Sustained Downlink Data
Rate. See
◦ Maximum Information Rate (MIR) Parameters on Page 85
◦ Interaction of Burst Allocation and Sustained Data Rate Settings on Page 88
