Chassis groups
You can group many chassis to form a multi-chassis management (MCM) group. An MCM group can have one leader chassis
and nine member chassis. You can use any management module to create an MCM group. The management module that is used
for creating the MCM is the leader of the group, by default. The MCM group can be of wired type. In the wired type, the chassis
is daisy-chained or wired through a redundant port on the management module. The chassis that you select for creating the
group must be daisy-chained to at least one chassis. You can view a list of wired chassis and select all or the required number of
chassis for creating the MCM group.
NOTE: You must have the chassis administrator privilege to create an MCM group.
You can perform the following tasks using an MCM group:
● View the health of the MCM group and the member chassis.
● Automatically apply settings of the leader chassis to member chassis.
● Perform any chassis operation on the MCM group.
You can add member chassis to an MCM group in two ways:
● Automatic—Enables automatic inclusion of the member to the chassis group. The automatic inclusion process does not
require approval from the chassis administrator.
● Manual—Mandates approval by the chassis administrator to include the member chassis to the chassis group.
Pre-requisites for creating a wired group
Following are the pre-requisites to create a wired or daisy-chained chassis group:
● List of wired daisy-chained chassis—All the chassis must be on the private stack. You need not enter a password as the
machine to machine authentication trust is used.
● Ensure that you have added member chassis to the group using the automatic or manual method.
● Ensure that the chassis settings are selected for applying to the other chassis—Power, user authentication, alert
destination, time, proxy, security, network services, local access.
Before creating an MCM group, ensure that the MX7000 management networks are wired together in a stacked configuration.
The stacked configuration helps in surviving:
● A single network cable failure.
● A single management module failure.
● Power loss owing to any chassis in the stack.
The wired chassis are displayed as under "Available Chassis" in the Group Deployment Wizard.
