CLI differences in IronWare release R07.2.02
The FastIron Configuration Guide and the section Documentation Updates in these release notes
describe the CLI differences in IronWare release 07.2.02 compared with earlier releases. No CLI
commands have been deprecated for this release.

Documentation Updates
This section contains documentation updates in this release.

Updates to SNTP feature
Release 07.2.02g introduces updates to the SNTP feature.
Specifying an SNTP server
You can configure the Brocade device to consult up to three SNTP servers for the current system time
and date. The first server configured will be used unless it becomes unreachable, in which case the
Brocade device will attempt to synchronize with the other SNTP servers (if any) in the order in which
they were configured.
Brocade devices do not retain time and date information across power cycles. Unless you want to
reconfigure the system time counter each time the system is reset, Brocade recommends that you use
the SNTP feature as described below.
IronWare Software Release 07.2.02j for Brocade FastIron switches
Release Notes v 1.0

Page 10 of 79

To identify an SNTP server with IP address 208.99.8.95 to act as the clock reference for a Brocade
device, enter the following.
Brocade(config)# sntp server 208.99.8.95

Syntax: [no] sntp server { | | ipv6 } [] [
authentication-key ]
The parameter specifies the SNTP version the server is running and can be from 1 – 4.
The default is 4. The SNTP version is automatically set to 4, unless a different SNTP version is specified in
the device startup configuration. You can configure up to three SNTP servers by entering three separate
sntp server commands.
The order in which the SNTP servers are configured is the order in which they are consulted. The server
that was configured first is the first server consulted after the poll cycle; the next server will be
consulted only if a positive ACK is not received from the first one.
To specify an IPv6 address for the SNTP server, use the ipv6 option.
The authentication-key option allows you to configure an authentication key for communication with
the SNTP server. When the authentication key is configured for an SNTP client, it is used only for an
SNTP unicast client. You must assign a unique server and pre-share . The
and pre-share are used together to create the MD5 checksum. The MD5 checksum is used
for authentication for request and reply messages with the SNTP server. The is the symmetric
key shared with the upstream server, and accepts values from 1 to 4,294,967,295. The is
the authentication string itself, and can take up to 16 characters. If the variable consists of
only numerical characters, you must enclose the numerical characters in double quotes.
Modification of the authentication key fields is not supported. To change the key ID or key string,
remove the time server using the no sntp server... command, then reconfigure the server with the new
key.
By default, the Brocade device polls its SNTP server every 30 minutes (1800 seconds). To configure the
Brocade device to poll for clock updates from a SNTP server every 15 minutes, enter the following.
Brocade(config)# sntp poll-interval 900

Syntax: [no] sntp poll-interval <16-131072>
To display information about SNTP associations, enter the show sntp associations command.

sntp poll-interval

Shows how often the Brocade device polls for clock updates from an SNTP

Configuring the device as an SNTP server
You can configure the Brocade device to function as an SNTP server to its downstream clients. When
using the device as an SNTP server, you can also set it to use its own internal clock as the reference
source if an upstream server becomes unavailable.
To use the device as an SNTP server, enter a command such as the following at the Privileged EXEC level.
Brocade(config)# sntp server-mode use-local-clock authentication-key abc123
Brocade(config)# write memory

The above example configures the device to operate as an SNTP server with the local clock as a
reference backup and an authentication key of “abc123” and writes the configuration changes to
memory.
Syntax: [no] sntp server-mode [ use-local-clock [ stratum ] ] [ authentication-key
]
The use-local-clock option causes the Brocade device to use the local clock as a reference source if an
upstream reference source becomes unavailable. The SNTP stratum number is set to 1 by default. You
may specify a different stratum number using the stratum option; must be between
1 and 15. When the internal clock is serving as the SNTP reference source, the Brocade device will use
IronWare Software Release 07.2.02j for Brocade FastIron switches
Release Notes v 1.0

Page 14 of 79

the specified stratum number (or the default value of 1). When it is synchronized with the upstream
server, the Brocade device will use the upstream server’s stratum number plus 1.
If you do not include the use-local-clock option the Brocade device will function as specified by RFC
4330: when the Brocade device loses upstream synchronization, it will respond to client SNTP requests
with a “kiss-of-death” response (stratum value=0).
To enable the use-local-clock option, you must set the internal clock of the Brocade device either by
SNTP synchronization (see “Specifying an SNTP server” on page 17) or by using the clock set command
(see “Setting the system clock” on page 30). Until the internal clock is set, the Brocade device will
continue to rely exclusively on an upstream SNTP server if one is reachable. If none, the SNTP server of
the Brocade device is disabled (down).
To require a code string for authentication of SNTP communication from clients, use the authenticationkey option and enter a key string of up to 16 characters. When this option is used, authentication
parameters are required in clients’ SNTP request messages. If authentication fails, the Brocade device
will reply with stratum 0 and a reference ID code of “CRYP” (cryptographic authentication or
identification failed), and messages received without the required parameters will be dropped.
NOTE: Once entered, the authentication key cannot be viewed. Using the show running-config
command will show output similar to the following when an authentication key has been set:
sntp server-mode authentication-key 2 $QHMiR3NzQA=

The 2 indicates that the key is encrypted using base-64 encryption; the characters following the 2 are
the encrypted authentication string.
You cannot enable or disable the use-local-clock option (or its stratum number) or change the
authentication string when the SNTP server is up. To change these settings after enabling SNTP server
mode, you must disable server mode using the command no sntp server-mode, then re-enable it with
the new parameters.
Displaying SNTP server information
Use the show sntp server-mode command to display the status of the SNTP server and its configuration.

number +1. If the device is unsynchronized and using the use-local-clock option,
this will show the user-specified stratum number (or the default value of “1” if no
stratum has been configured).

authentication

Authentication key used. If authentication has been configured successfully, this
displays “md5.” If not, it displays “none.”

clock source

The source of the reference time. When the reference source is an upstream
SNTP server, this will show the IP address of the upstream server. When the
internal clock of the device is being used as the reference, this will show “localclock.”

last upstream sync

The last upstream time-server synchronization, displayed in timestamp format.
This field is not displayed if the time source is the local clock.

last responses sent
to clients

The last responses sent to downstream clients (maximum of five unique clients),
displayed in reverse chronological order. Each entry shows the IP address of the
client and the timestamp sent.

Enabling broadcast mode for an SNTP client
The Brocade device can be configured as an SNTP client. You can enable an SNTP client to function in a
broadcast mode when the NTP server is within the same LAN, and the expected delay in response to
calibrate the system clock is minimal. In a broadcast mode, the SNTP client will not send queries to the
NTP server. The SNTP client will listen to any number of NTP servers on the network until the last
message is received from the system clock. To update the system clock with the last message received,
you can enable the SNTP client to either listen to all NTP broadcast servers on any interface, or enable
the SNTP client to listen to only one specific NTP broadcast server.
To enable an SNTP client in a broadcast mode to listen to all NTP servers on any interface, enter the sntp
broadcast client command.
Brocade(config)#sntp broadcast client

Syntax: sntp broadcast client
The sntp broadcast client command enables an SNTP client to listen to all NTP servers, and update the
client’s clock with the last message received from any NTP server.
To enable an SNTP client to listen to only one specific IPv4 NTP broadcast server, enter the following
commands.
IronWare Software Release 07.2.02j for Brocade FastIron switches
Release Notes v 1.0

Page 16 of 79

Brocade(config)#sntp broadcast client
Brocade(config)#sntp broadcast server 1.1.1.1

To enable an SNTP client to listen to only one specific IPv6 NTP broadcast server, enter the following
commands.
Brocade(config)#sntp broadcast client
Brocade(config)#sntp broadcast server ipv6 2001:179:2:1::1

Syntax: sntp broadcast server [ | ipv6 ]
The sntp broadcast client command must be configured with the sntp broadcast server command to
allow for an SNTP client to listen to only one specific NTP server.
When both unicast and broadcast modes are enabled for an SNTP client, the priority by which the NTP
server is used to update the client’s clock is as follows.
•

The last responsive unicast server.

•

The broadcast server on any interface.

qd commands on FGS and FLS devices
Information on configurable descriptor and configurable buffer for qd commands for FGS and FLS
devices in the configuration guide is incorrect.
•

The maximum configurable descriptors using the qd-descriptor command is 3999.

•

The maximum configurable buffer using the qd-buffer command is 2904.

Flow control on SuperX devices
The FastIron Configuration Guide states that all FastIron devices support asymmetric flow control,
meaning they can receive PAUSE frames but cannot transmit them. This is true for FastIron devices with
the exception of SuperX devices; symmetric flow control is turned on by default on SuperX devices.

SSH key generation time
The authentication and encryption algorithms have changed to be more secure. The increased security
affects SSH key generation time. The new SSH key generation time ranges apply only to initial key
generation. Refer to the following table for initial SSH key generation time ranges.

VRRP show command output
In some of the VRRP show command outputs in the FastIron Configuration Guide, Hello-Interval and
Dead-Interval timers are displayed in seconds instead of milliseconds.

48-port 10/100/1000 Mbps Ethernet POE (SX-FI48GPP) interface module
limitations
The following configuration limitations apply to this module:
•
•

Q-in-Q and SAV (VLAN stacking) are not supported on this module.
For systems with this module and IPv4 or IPv6 interface modules or management modules with user
ports:
• GRE tunnels and IPv6 over IPv4 tunnels are not supported.
NOTE: If the SX-FI48GPP module is inadvertently inserted in a system that has IPv4 or IPv6
interface modules, or a management module with user ports, existing tunnels will be taken
down immediately. To recover, you must physically remove the module that caused the
mix-and-match condition, then disable and re-enable the tunnel interfaces.

•

• Legacy ports and 48 Gbps copper ports cannot be members of the same trunk.
Virtual cable testing (CLI command phy cable-diag tdr) is not supported on the SX-FI48GPP module
in software release 07.2.02.

New limit for IPv4 system-max ip-cache
For FCX and FastIron X Series devices, the maximum value for system-max ip-cache (IPv4) is reduced
from 256000 to 32768. When you upgrade to release 07.2.02 and if your configuration has an ip-cache
value greater than 32768, it will be automatically reduced to 32768.

ACL Statistics on FGS, FLS, and FWS devices
The FGS, FLS, and FWS do not support the use of traffic policies for ACL statistics only (CLI command
traffic-policy count). However, these models do support the use of traffic policies for ACL
statistics together with rate limiting traffic policies. For more information, refer to “Enabling ACL
statistics with rate limiting traffic policies” in the FastIron Configuration Guide.

IGMP Snooping feature limitation on FESX, SuperX, and FSX devices
High CPU utilization will occur when IGMP Snooping and PIM/DVMRP routing are enabled
simultaneously on a FESX, SuperX, or FSX router. With IGMP Snooping and PIM/DVMRP Routing
enabled simultaneously on a given system, IP Multicast data packets received in the snooping VLAN(s)
will be forwarded to client ports via the hardware; however, copies of these packets will also be
received and dropped by the CPU.

Show interface brief command output
If a port name is longer than 8 characters, the port name will be truncated in the output of the show
interface brief command.
IronWare Software Release 07.2.02j for Brocade FastIron switches
Release Notes v 1.0

Page 18 of 79

ICMP redirect messages
In software release 07.2.02, ICMP redirect messages are disabled by default, whereas in releases prior to
07.2.02, ICMP redirect messages are enabled by default.
•

•

If ICMP redirect messages were enabled prior to upgrading to release 07.2.02, you will need to reenable this feature after upgrading to 07.2.02. To do so, enter the ip icmp redirect command at the
global CONFIG level of the CLI.
If ICMP redirect messages were disabled prior to upgrading to release 07.2.02, the configuration (no
ip icmp redirect) will be removed from the configuration file after upgrading to 07.2.02, since this
feature is now disabled by default. In this case, ICMP redirect messages will not be sent and no
further action is required.

Enabling and Disabling DHCP-client service on FSX Base Layer 3 devices
By default, DHCP-client service is enabled. If the DHCP-Server is connected to an interface on a FSX Base
Layer 3 device, the interface is assigned a leased IP address. To disable DHCP-client service on an
interface on a FSX Base Layer 3 device, and assign a new IP address, enter the following commands.
1. Disable DHCP-client on the interface. For example, enter a command such as the following.
FastIron(config-if-e1000-3/1)# no ip dhcp-client enable

Syntax: no ip dhcp-client enable
2. To save the configuration, enter the write memory command on the CLI as displayed in the
following example.
FastIron(config)# write memory
FastIron(config)# end

3. Reload the FSX Base Layer 3 device by entering the following command:
FastIron# reload

The DHCP-client service feature is now removed from the interface.
To enable DHCP-client service on an interface on a FSX Base Layer 3 device when a static IP address is
assigned to the interface, enter the following commands.
1. Remove the static IP address assigned to the interface. For example, enter a command such as
the following.
FastIron(config-if-e1000-3/1)# no ip address 10.10.10.10/24

Syntax: no ip address
2. To save the configuration, enter the write memory command on the CLI as displayed in the
following example.
FastIron(config)# write memory
FastIron(config)# end

3. Reload the FSX Base Layer 3 device by entering the following command:
FastIron# reload

IronWare Software Release 07.2.02j for Brocade FastIron switches
Release Notes v 1.0

Page 19 of 79

Once the device has reloaded, the DHCP-client service will start up and a new dynamic IP address is
assigned to the interface. The DHCP-client service feature is now enabled on the interface.

Note regarding Telnet and Internet Explorer 7
The Telnet function in Web management does not work with Internet Explorer version 7.0.5730. The
system goes to "telnet://10.43.43.145" page when the user clicks web/general system configuration/
(telnet) in Internet Explorer version 7.0.5730. This is a known issue for Internet Explorer. To work
around this issue, you must download and install a patch for IE 7. To do so, go to
http://www.lib.ttu.edu.tw/file/IE7_telnet.reg.
Note regarding US-Cert advisory 120541
In order to address the SSL and TLS vulnerability issue discussed in US-Cert advisory 120541, the Web
server re-negotiation feature has been disabled in this release so that SSL re-negotiation requests will
not be honored by the Brocade IP device Web server.
Based on Cert advisory 120541, the Secure Sockets Layer (SSL) and Transport Layer Security (TLS)
protocols are vulnerable to Man-In-The-Middle (MITM) attacks. Vulnerability is in the way SSL and TLS
protocols allow re-negotiation requests, which may allow a MITM to inject arbitrary requests into an
application HTTP protocol stream. This could result in a situation where the MITM may be able to harm
the Brocade IP device through the Web Management interface.
For more information regarding Cert advisory 120541, refer to the following links:

NOTE: The PoE circuitry includes a microcontroller pre-programmed at Brocade factory. In the past, a
copy of the current microcontroller code was embedded as part of the FastIron software releases and
was used for upgrades if necessary. Two different types of PoE controller code sets were included for
PoE and POE+ subsystems. That is no longer the case, and the software has been enhanced so that it can
be loaded as an external file. The microcontroller code has not changed in this release, so there is no
current need for an upgrade.
Should a new version of POE code be released, Brocade will notify its customers of the needed code
upgrade. Finally, in the remote case that a failure occurs during an upgrade process, the switch would

still be functional but without PoE circuitry. Should you encounter such an issue, please contact Brocade
Technical Support for servicing.

Upgrading the software
Use the procedures in this section to upgrade the software.

Important notes about upgrading or downgrading the software
Note the following when upgrading to software release 07.2.02j:
•

•

If you are performing an upgrade on a device that has an XFP optic that is not working properly and
the device is running a software release prior to 07.2.02j, you must remove the XFP optic from the
port after the upgrade, then re-insert it into the port.
To upgrade an FWS device running software version 04.3.00 to version 07.2.02j, you must first
upgrade to release 04.3.02 before upgrading to 07.2.02j. For instructions on how to upgrade to
release 04.3.02, see the 04.3.02 release notes.
To upgrade FGS standalone devices from software release 04.3.02 to version 07.2.02j with the
intent of forming a stack, first upgrade the units individually (in standalone mode) without
connecting the stacking cables. After upgrading all of the FGS units, you can then connect the
stacking cables.
If FGS-STK or FLS-STK devices are upgraded from software release 04.3.00 non-stacking mode to
release 07.2.02j stacking mode, these devices may lose some port-related functions. If you are
upgrading from a pre-stacking release to a stacking release, refer to “Converting from a pre-stacking
image to a stacking image” in the FastIron Configuration Guide.

Note the following when downgrading from software release 07.2.02j:
•
•
•

•

FCX-F devices require software release 06.1.00 or later.
If software-based licensing is in effect on the device and the software is downgraded to pre-release
07.1.00, software-based licensing will not be supported.
If FCX units in an IronStack are downgraded from software release 07.2.02j to release 06.0.00, in
some instances, the units may not be able to form a stack. This will occur if there is a mismatch of
BGP capability within the stack (i.e., some units support it and others do not). If you encounter this
problem, contact Brocade Technical Support for assistance.
For FCX units, the 10G module name differs in software release 07.2.02j compared to releases
07.0.01b and 07.0.01c. Therefore, if an FCX is downgraded from software release 07.2.02j to release
07.0.01b or 07.0.01c, the stacking port configuration will be lost and the unit will not be able to join
the stack.
If FGS-STK or FLS-STK units in an IronStack are downgraded from software release 07.2.02j to release
04.3.00, these units may lose some port-related functions since 04.3.00 does not support stacking.
The same issue applies when FGS or FLS (standalone) devices that use stack-unit ID 2 or greater are
downgraded from release 07.2.02j to 04.3.00. This will occur because the default non-stacked port
numbering scheme in release 4.3.00 and earlier is 0/x/x, versus the new non-stacked port
numbering scheme in 7.0 which is 1/x/x. After downgrading from release 7.0.01b to 4.3.00 or

IronWare Software Release 07.2.02j for Brocade FastIron switches
Release Notes v 1.0

Page 40 of 79

earlier, all configuration items relating to port numbers will be invalid and will need to be
reprogrammed in the switch.

Upgrading the software to the new release
This section describes how to upgrade the software to run release 07.2.02j.
Before upgrading the software on the device, first read Important notes about upgrading or
downgrading the software.
Upgrading the boot code
To upgrade the boot code, perform the following steps.
1. Place the new boot code on a TFTP server to which the Brocade device has access.
2. If the device has 8 MB of flash memory or if you want to install a Full Layer 3 image on an
SuperX or SX device, you must delete the primary and secondary image
3. Copy the boot code from the TFTP server into flash memory. To do so, enter a command such as
the following at the Privileged EXEC level of the CLI.
copy tftp flash bootrom
You should see output similar to the following.
FastIron Router# Flash Memory Write (8192 bytes per

dot)...........................
(Boot Flash Update)Erase.........Write.............
TFTP to Flash Done

NOTE: Brocade recommends that you use the copy tftp flash command to copy the boot code
to the device during a maintenance window. Attempting to do so during normal networking
operations may cause disruption to the network.
4. Verify that the code has been successfully copied by entering the following command at any
level of the CLI.
show flash
The output will display the compressed boot ROM code size and the boot code version.
5. Upgrade the flash code as instructed in the following section.
Upgrading the flash code
NOTE: You must delete the current primary and secondary images before completing the upgrade
steps. Devices with 8MB of flash memory can only hold one complete image.
To upgrade the flash code, perform the following steps.
1. Place the new flash code on a TFTP server to which the Brocade device has access.
2. If the device has 8MB of flash memory or if you want to install a Full Layer 3 image on an FWS,
SuperX or FSX device, you must delete the primary and secondary images before upgrading the
image. To delete images from the flash, enter the following commands:

IronWare Software Release 07.2.02j for Brocade FastIron switches
Release Notes v 1.0

Page 41 of 79

FastIron Router# erase flash primary
FastIron Router# erase flash secondary

NOTE: If the primary flash contains additional files not related to the software update, it is
recommended that you also delete these files.
3. Copy the flash code from the TFTP server into flash memory. To do so, use the copy command
at the Privileged EXEC level of the CLI.
copy tftp flash primary | secondary
You should see output similar to the following.
FastIron Router# Flash Memory Write (8192 bytes per dot)

........................
.......................................................................
.......................................................................
.....
TFTP to Flash Done

4. Verify that the flash code has been successfully copied by entering the following command at
any level of the CLI.
NOTE: For units in an IronStack, when upgrading from one major release to another (for
example, from software release 07.1.00 to 07.2.00), make sure that every unit has the same
code. If you reload the stack while units are running different code versions, the units will not
be able to communicate.
show flash
If the flash code version is correct, go to step 5, otherwise, go back to step 1.
5. Once you have completed the upgrade, you must reboot the device to complete the upgrade
process. Use one of the following commands:
•
•

reload (this command boots from the default boot source, which is the primary flash area
by default)
boot system flash primary | secondary

A confirmation step may occur after a boot system flash primary/secondary command is
entered and gives an administrator the opportunity to make last minute changes or corrections
before performing a reload. The example below shows the confirmation step.
FWS648POE Router# boot system flash primary
Are you sure? (enter ‘Y’ or ‘N’): y

6. For FGS-STK and FLS-STK devices equipped with upgraded memory DIMMs, EEPROM, or both, if
you encounter a problem after reloading the software, make sure the device has the correct
boot code version and the following (if applicable) are installed correctly:
•
•

EEPROM
Memory DIMM

Release Notes v 1.0

Page 42 of 79

NOTE: If the stacking EEPROM is missing or is not installed correctly, or if you have installed the
wrong EEPROM, you will see an error message on the console. For details, see the FastIron
Configuration Guide.
6. For devices in an IronStack, make sure all devices are running the same software image. See
“Confirming software versions (IronStack devices)” in the next section.
Confirming software versions (IronStack devices)
All units in an IronStack must be running the same software image. To confirm this, check the software
version on all devices that you want to add to your IronStack. Upgrade any units that are running older
versions of the software before you build your stack.
1. Telnet, SSH, or connect to any of the console ports in the stack.
2. Enter the show version command. Output similar to the following is displayed.
NOTE: This example output may not exactly match the output from your system. Output
examples do not necessarily reflect all components installed in a system.
