Chapter 5 Clustering Switches
Using SNMP to Manage Switch Clusters
Note When a cluster standby group is configured, the cluster command switch can change without your
knowledge. Use the first read-write and read-only community strings to communicate with the cluster
command switch if there is a cluster standby group configured for the cluster.
If the cluster member switch does not have an IP address, the cluster command switch redirects traps
from the cluster member switch to the management station, as shown in Figure 5-1. If a cluster member
switch has its own IP address and community strings, the cluster member switch can send traps directly
to the management station, without going through the cluster command switch.
If a cluster member switch has its own IP address and community strings, they can be used in addition
to the access provided by the cluster command switch. For more information about SNMP and
community strings, see Chapter 27, “Configuring SNMP.”
