Cluster Command Switch Characteristics; Standby Cluster Command Switch Characteristics - Cisco WS-C3560-48PS-S Software Configuration Manual

Chapter 5 Clustering Switches

Cluster Command Switch Characteristics

A cluster command switch must meet these requirements:
•
•
•
•
•
If your switch cluster has a Catalyst 3560 switch, it should be the cluster command switch unless the
Note
cluster has a Catalyst 3750 switch or switch stack. If the switch cluster has a Catalyst 3750 switch or
switch stack, that switch or switch stack must be the cluster command switch.

Standby Cluster Command Switch Characteristics

A standby cluster command switch must meet these requirements:
•
•
•
•
•
•
•
Note Standby cluster command switches must be the same type of switches as the cluster command switch.
For example, if the cluster command switch is a Catalyst 3560 switch, the standby cluster command
switches must also be Catalyst 3560 switches. Refer to the switch configuration guide of other
cluster-capable switches for their requirements on standby cluster command switches.

It has an IP address.
It has CDP version 2 enabled.
It is connected to the command switch and to other standby command switches through its
management VLAN.
It is connected to all other cluster member switches (except the cluster command and standby
command switches) through a common VLAN.
It is redundantly connected to the cluster so that connectivity to cluster member switches is
maintained.
