Chapter 5 Clustering Switches

Discovery Through Different VLANs

If the cluster command switch is a Catalyst 2970, Catalyst 3550, Catalyst 3560, or Catalyst 3750 switch,
the cluster can have cluster member switches in different VLANs. As cluster member switches, they
must be connected through at least one VLAN in common with the cluster command switch. The cluster
command switch in
switches in those VLANs. It does not discover the switch in VLAN 50. It also does not discover the
switch in VLAN 16 in the first column because the cluster command switch has no VLAN connectivity
to it.
Catalyst 2900 XL, Catalyst 2950, and Catalyst 3500 XL cluster member switches must be connected to
the cluster command switch through their management VLAN. For information about discovery through
management VLANs, the
more information about VLANs, see

Command switch

Discovery Through Different Management VLANs

Catalyst 2970, Catalyst 3550, Catalyst 3560, or Catalyst 3750 cluster command switches can discover
and manage cluster member switches in different VLANs and different management VLANs. As cluster
member switches, they must be connected through at least one VLAN in common with the cluster
command switch. They do not need to be connected to the cluster command switch through their
management VLAN. The default management VLAN is VLAN 1.
Note If the switch cluster has a Catalyst 3750 switch or switch stack, that switch or switch stack must be the
cluster command switch.
