Management Module Redundancy Configuration; Changing The Default Active Chassis Slot; Managing Management Module Redundancy - Dell PowerConnect B-RX Configuration Manual

The interface modules are not reset, as they are with the previous cold-restart redundancy feature.
The interface modules continue to forward traffic while the standby management module takes
over operation of the system. The new now-active management module receives updates from the
interface modules and sends verification information to the interface modules to ensure that they
are synchronized.
If the new active management module becomes out-of-sync with an interface module, information
on the interface module can be overwritten in some cases which can cause an interruption of
traffic forwarding. Layer 3 hitless failover is not supported in this release. Consequently, a failover
will result in a re-synchronization of Layer 3 data structures

Management module redundancy configuration

Configuring management module redundancy consists of performing one optional task (changing
the default active chassis slot). The section explains how to perform this task.

Changing the default active Chassis slot

By default, the BigIron RX Series system considers the module installed in slot M1 to be the active
management module. If desired, you can change the default active chassis slot to M2.
The active-management command determines which management module will become active
after a power cycle. By default, the top or left mgmt module will become active after power cycle.
This information is stored in the chassis's backplane eeprom, and not in the configuration file. This
is a chassis specific configuration.
To change the default active chassis slot to M2, enter the following commands.
BigIron RX(config)# redundancy
BigIron RX(config-redundancy)# active-management mgmt-2
Syntax: active-management <mgt-module>
The <mgt-module> parameter specifies the management module, which can be mgmt-1 or
mgmt-2.
NOTE
This configuration has no effect on the "reload" and "boot ..." commands. It only applies to the power
cycle when both MPs are in the chassis.
