Management module redundancy configuration
5
Management sessions
You can establish management sessions with the active management module’s management port.
If a switchover occurs, the management port on the original active module shuts down and all open
CLI, Web Management Interface, and Brocade Network Advisor sessions with that port close. You
can open new sessions with the new active module, provided that the new active module has the
same management port connections. (For example, if you were accessing the Web Management
Interface through a PC connected to the original active module’s management port, you can open a
new session if a PC is connected to the new active module’s management port.)
In the scenario described above, you can open a new session using the same IP address you were
using before the switchover. (You configure an IP address for the active module only; if a switchover
occurs, the IP address is used by the new active module.)
Syslog and SNMP traps
When a switchover occurs, the system sends a Syslog message to the local Syslog buffer and also
to the Syslog server, if you have configured the system to use one. In addition, if you have
configured an SNMP trap receiver, the system sends an SNMP trap to the receiver.
When the system is powered on or otherwise reset normally, the system sends a cold start
message and trap. However, if the system is reset as the result of switchover to the standby
management module, the system instead sends a warm start message and trap.
MAC address changes
The MAC addresses in the system are based on the MAC address of the chassis. During switchover,
the system's MAC addresses do not change.
Management module redundancy configuration
Configuring management module redundancy consists of performing one optional task (changing
the default active chassis slot). The following section explains how to perform this task.
Changing the default active chassis slot
By default, the system considers the module installed in the lower-numbered slot to be the active
management module. If desired, you can change the default active chassis slot to the
higher-numbered slot.
To change the default active chassis slot, enter commands such as the following.
Brocade# config t
Brocade(config)# set-active-mgmt mgmt1
Syntax: [no] set-active-mgmt mgmt0 | mgmt1
mgmt0 is the lower-numbered slot and mgmt1 is the higher-numbered slot.
To remove the configuration, use the no form of the command. You cannot use the erase startup
command to remove the configuration.
To view the default active chassis slot currently configured on the device, use the show run
command.
