3.4 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.
