Planning a Switch Cluster
shows that the cluster command switch discovers the switch that is connected to a third-party
hub. However, the cluster command switch does not discover the switch that is connected to a
Catalyst 5000 switch.

Discovery Through Non-CDP-Capable and Noncluster-Capable Devices
Discovery Through Different VLANs
If the cluster command switch is a Catalyst 3560-E or Catalyst 3750-E 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

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
has ports assigned to VLANs 9, 16, and 62 and 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
