Configuring a Cluster

To set up a cluster of two switches, say, pleiades1 and pleiades2, you must first verify that they both belong to the same fabric instance, in this case corp-fab:

CLI (network-admin@switch) > fabric-node-show layout vertical

id: 184549641

name: pleiades1

fab-name: corp-fab

fab-id: b000109:5695af4f

cluster-id: 0:0

local-mac: 3a:7f:b1:43:8a:0f

fabric-network: in-band

control-network: in-band

mgmt-ip: 10.9.19.203/16

mgmt-mac: ec:f4:bb:fe:06:20

mgmt-secondary-macs:

in-band-ip: 192.168.168.203/24

in-band-mac: 3a:7f:b1:43:8a:0f

in-band-vlan: 0

in-band-secondary-macs:   

fab-tid: 1

cluster-tid: 0

out-port: 0

version: 2.4.204009451,#47~14.04.1-Ubuntu

state: online

firmware-upgrade: not-required

device-state: ok

ports: 104

To create a cluster configuration, use the following command:

CLI (network-admin@switch) > cluster-create name cluster1 cluster-node-1 pleiades1 cluster-node-2 pleiades2

To verify the status of the cluster, use the cluster-show command:

CLI (network-admin@switch) > cluster-show

name      state   cluster-node-1  cluster-node-2

--------- ------- --------------- --------------

cluster1  online  pleiades1       pleiades2

To replace a failed cluster node, use the fabric-join repeer-to-cluster-node command.

However, you must evict the failed node from the fabric, and then run the fabric-join repeer-to-cluster-node command on an active node after replacing the failed node.

To display information about the cluster, use the cluster-info command:

CLI (network-admin@switch) > cluster-info format all layout vertical
