6.3 Examples of Cluster Administration
Scenario:
The four switches SW1-SW4, amongst the SW1 is the command switch and other switches are member
switch. The SW2 and SW4 is directly connected with the command switch, SW3 connects to the command
switch through SW2.
Figure 6-1 Examples of Cluster
Configuration Procedure
1. Configure the command switch
Configuration of SW1:
Switch(config)#cluster run
Switch(config)#cluster ip-pool 10.2.3.4
Switch(config)#cluster commander 5526
Switch(config)#cluster auto-add
2. Configure the member switch
Configuration of SW2-SW4
Switch(config)#cluster run
6.4 Cluster Administration Troubleshooting
When encountering problems in applying the cluster admin, please check the following possible causes:
 If the command switch is correctly configured and the auto adding function (cluster auto-add) is
enabled. If the ports connected the command switch and member switch belongs to the cluster vlan.
 After cluster commander is enabled in VLAN1 of the command switch, please don’t enable a routing
protocol (RIP, OSPF, BGP) in this VLAN in order to prevent the routing protocol from broadcasting the
private cluster addresses in this VLAN to other switches and cause routing loops.
 Whether the connection between the command switch and the member switch is correct. We can use
the debug cluster packets to check if the command and the member switches can receive and process
related cluster admin packets correctly.
