Chapter 5 Clustering Switches
Planning a Switch Cluster
Considerations for Cluster Standby Groups
In addition to providing a virtual IP address to the cluster standby group, these requirements apply:
When the command switch is a Catalyst 3550 switch, all standby command switches must be
Catalyst 3550 switches or Catalyst 2950 switches running Cisco IOS Release 12.1(6)EA2 or later.
When the command switch is a Catalyst 2950 switch running Cisco IOS Release 12.1(6)EA2 or
later, all standby command switches must be Catalyst 2950 switches running Cisco IOS
Release 12.1(6)EA2 or later.
When the Catalyst 2950 command switch is running Cisco IOS Release 12.0(5)WC2 or earlier, the
standby command switches can be these switches also running Cisco IOS Release 12.0(5)WC2 or
earlier: Catalyst 2900 XL, Catalyst 2950, and Catalyst 3500 XL switches.
We recommend that the standby command switches be of the same platform family as the command
switch. For example, a cluster with a Catalyst 2950 command switch should have Catalyst 2950
standby command switches.
Only one cluster standby group can be assigned to a cluster.
All standby-group members must be members of the cluster.
Note There is no limit to the number of switches you can assign as standby command switches.
However, the total number of switches in the clusterwhich would include the active
command switch, standby-group members, and member switchescannot be more
than 16.
The active command switch must be connected through its management VLAN to each
standby-group member (Figure 5-6). Each standby-group member must also be redundantly
connected to each other through the management VLAN.
Catalyst 1900, Catalyst 2820, Catalyst 2900 XL, Catalyst 2950, and Catalyst 3500 XL member
switches must be connected to the cluster standby group through their management VLANs.
For more information about VLANs in switch clusters, see these sections:
Discovery through Different Management VLANs sectiononpage5-8
Discovery through the Same Management VLAN sectiononpage5-7
