5.3 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 5-1 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

5.4 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.
