Discovery Through Different Management Vlans - Cisco Catalyst 2950 Software Manual

Planning a Switch Cluster

Discovery through Different Management VLANs

We strongly recommend that a Catalyst 3550 switch be the command switch when the cluster has
Catalyst 1900, Catalyst 2820, Catalyst 2900 XL, Catalyst 2950, and Catalyst 3500 XL member
switches. These member switches must connect to each other and to a Catalyst 3550 command switch
through their management VLAN, which is VLAN 1 by default. When these member switches are
directly connected to a Catalyst 3550 command switch, the management VLAN of these member
switches can be different.
For information about discovery through the same management VLAN on these switches, see the
"Discovery through the Same Management VLAN" section on page
