Chapter 6 Clustering Switches
Discovery Through Different VLANs
If the cluster command switch is a Catalyst 3560-E, Catalyst 3750-E, Catalyst 3560-X, or Catalyst
3750-X 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
therefore discovers the 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, see the

Discovery Through Different Management VLANs
Catalyst 2960, Catalyst 2970, Catalyst 3550, Catalyst 3560, Catalyst 3560-E, Catalyst 3750,
Catalyst 3750-E, Catalyst 3560-X, or Catalyst 3750-X 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.
