How to Plan for Switch Clustering
Figure 8 Discovery Through Non-CDP-Capable and Noncluster-Capable Devices
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 Figure 9 on page 97 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 management VLANs, see
Discovery Through Different Management VLANs, page 97.
