Configuration Notes and feature limitations
This section contains configuration notes and describes some feature limitations in this release:

Additional notes on trunk group rules
The following additional considerations apply to forming trunk groups:
•

Legacy ports and 48 Gbps copper ports cannot be members of the same trunk group in hardware
configurations such as the following:
• 48-port 10/100/1000 Mbps (RJ45) Ethernet PoE interface module (SX-FI48GPP) and IPv4/IPv6 interface
modules or management modules with user ports.
Combination of different generations of ports cannot be members of the same trunk group under the following
hardware configurations:
• 24-port fiber and copper Ethernet PoE/Fiber interfaces (SX-FI24GPP, SX-FI24GF) and IPv4/IPv6 interface
modules or management modules with user ports
• 2-port 10G and 8-port 10G interfaces (SX-FI8XG, SX-FI2XG) and the IPv4/IPv6 interface modules or
management modules with user ports

SNTP version configuration during upgrade
Starting with release 7.3.00, the default SNTP version is 4. In previous releases, the default SNTP version was
1. When you upgrade to release 7.3.00, the SNTP version gets set automatically to 4, unless a different SNTP
version is specified in the device startup configuration.

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

IronWare Software Release R07.3.00c Brocade FastIron FSX and FESX (IPv6 Models) Switches
Release Notes v4.0
Page 14 of 80

•
•

If ICMP redirect messages were enabled prior to upgrading to release 07.2.02 and later, you will need to
re-enable this feature after upgrading to 07.2.02 and later. 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 and later, the configuration
(no ip icmp redirect) will be removed from the configuration file after upgrading to 07.2.02 and later, since
this feature is now disabled by default. In this case, ICMP redirect messages will not be sent and no
further action is required.

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 renegotiation 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.

DHCPv6 relay agent
A client locates a DHCP server using a reserved, link-scoped multicast address. Direct communication between
the client and server requires that they are attached by the same link. In some situations where ease-ofmanagement, economy, and scalability are concerns, you can allow a DHCPv6 client to send a message to a
DHCP server using a DHCPv6 relay agent.
A DHCPv6 relay agent, which may reside on the client link, but is transparent to the client, relays messages
between the client and the server. Multiple DHCPv6 relay agents can exist between the client and server.
DHCPv6 relay agents can also receive relay-forward messages from other relay agents; these messages are
forwarded to the DHCP server specified as the destination.
When the relay agent receives a message, it creates a new relay-forward message, inserts the original DHCPv6
message, and sends the relay-forward message as the DHCP server.
Configuring the DHCPv6 relay agent
To enable the DHCPv6 relay agent function and specify the relay destination (the DHCP server) address on an
interface, enter the following command at the interface level:
Brocade(config-if-e1000-2/3)#ipv6 dhcp-relay destination 2001::2
Syntax: [no] ipv6 dhcp-relay destination 
Specify the  as a destination address to which client messages are forwarded and which
enables DHCPv6 relay service on the interface. You can configure up to 16 relay destination addresses on an
interface.
Use the [no] version of the command to remove a DHCPv6 relay agent from the interface.
Displaying DHCPv6 relay agents
The show ipv6 dhcp-relay command displays the DHCPv6 relay agents configured on the device:
Brocade(config)# show ipv6 dhcp-relay

Enabling the detection of PoE power requirements advertised through CDP
The dynamic configuration of a PoE powered device such as a wireless access point (AP) or a VoIP device uses
an initial discovery process. Upon installation, and sometimes periodically, a device will query the Brocade
device for available power information and will advertise information about itself, such as, device ID, port ID,
and power request. When the Brocade device receives the query, it sends the power available in a reply packet
back to the device. The device then configures itself to draw power up to the power level available to it.

SNTP authentication key configuration
The authentication-key   option is used to configure an authentication key for
communication with the SNTP server. If the  variable consists of only numerical characters, you
must enclose the numerical characters in double quotes.

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 L3
device, the interface is assigned a leased IP address. To disable DHCP-client service on an interface on a FSX
Base L3 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 L3 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 L3 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 192.0.2.0/24

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 L3 device by entering the following command:
FastIron# reload

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.

Upgrading software for FSX and FESX6
Use the procedures in this section to upgrade the software for FSX and FESX6.

Important notes about upgrading or downgrading the software
Note the following when upgrading to software release R07.3.00c:
•
•
•

FSX devices can store two Full Layer 3 image or two Layer 2 or Base Layer 3 images.
FESX6 can store one Full Layer 3 image or two Layer 2 or Base Layer 3 images
The image for IronWare R07.2.00a and later uses different Interprocessor Communications (IPC) versions
for FCX devices; however, units in a stack must run the same IPC version to communicate. After upgrading
from IronWare R07.2.00 or earlier to IronWare R07.3.00c, you must verify that the same image
downloaded to every unit in the stack before reloading the entire stack. To verify the images, you can enter
the show flash command at any level of the CLI. A stack cannot be built and will not operate if one or more
units has different software images.

Note the following when downgrading from software release R07.3.00c:
•

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.

Standard upgrade procedure
Before upgrading the software on the device, first read the “Important notes about upgrading or downgrading
the software” section.

PoE Firmware files
Table 15 lists the PoE firmware file types supported for IronWare Release R07.3.00c. The firmware files are
specific to their devices and are not interchangeable. For example, you cannot load FCX PoE firmware on a FSX
device.
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. Brocade is still on the initial release of the microcontroller code, so there is no current need for
an upgrade. The PoE firmware version string will be kept updated to match the corresponding FastIron
software version; however, this is only a cosmetic change and the firmware itself remains unchanged. Should
a new version of the 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 boot code
If you need 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 FCX or FSX
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.
Device# 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 FCX device,
you must delete the primary and secondary images before upgrading the image. To delete images
from the flash, enter the following commands:
Device# erase flash primary
Device# 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.
Device# 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.
Device# boot system flash primary
Are you sure? (enter ‘Y’ or ‘N’): y
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.
Device# show version

Open defects in Release 07.3.00
This section lists defects with High or Medium Technical Severity as of December 9, 2011. The presence of a
defect in this list can be prompted by several different circumstances. For example, some defects may have
been initially reported against an earlier release in the field. Brocade’s standard process in such cases is to
open defects against the current release that might experience the same issues, and close them only when a
fix is implemented, or if it is determined that the problem does not exist with the current release.
In other cases, a fix has been developed but has not been implemented in this release because it requires
particularly extensive code changes or regression testing to ensure that the fix does not create new problems.
Such fixes will appear in future releases.
None of these defects have the requisite combination of probability and severity to cause significant concern
to Brocade customers.
Note that when a workaround to an issue is available, it is provided; otherwise, no recommended workaround
is available at this time.
