Chassis groups You can group many chassis to form a multi-chassis management (MCM) group. An MCM group can have one lead chassis and 19 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 is of wired type, where 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. Prerequisites for creating a wired group Following are the prerequisites 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. • Ensure that Auto Negotiation is set to true in all the chassis that are connected to form an MCM group. For more information, see Configuring chassis network. • Before stacking the chassis for creating a group or adding new members to the existing group, ensure that all the chassis have the same OME-Modular firmware version. Before creating an MCM group, ensure that the MX7000 management networks are wired together in a stacked configuration. The stacked configuration helps in surviving: 30 Logging in to OME-Modular

Chassis groups
You can group many chassis to form a multi-chassis management (MCM) group. An MCM group can have one lead chassis and 19
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 is of wired type, where 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.
Prerequisites for creating a wired group
Following are the prerequisites 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.
•
Ensure that Auto Negotiation is set to true in all the chassis that are connected to form an MCM group. For more information, see
Configuring chassis network
.
•
Before stacking the chassis for creating a group or adding new members to the existing group, ensure that all the chassis have the
same OME-Modular firmware version.
Before creating an MCM group, ensure that the MX7000 management networks are wired together in a stacked configuration. The
stacked configuration helps in surviving:
