Sample cluster configurations
The following example can be used to configure a four-node cluster with ECMP, cluster LA, or Linksets.
-
Create the cluster.
-
Log on to the first node.
-
Add the cluster instance.
> add cluster instance 1 -
Add the first node to the cluster.
> add cluster node 0 10.102.33.184 -backplane 0/1/1 -
Enable the cluster instance.
> enable cluster instance 1 -
Add the cluster IP address.
> add ns ip 10.102.33.185 255.255.255.255 -type CLIP -
Save the configurations.
> save ns config -
Warm reboot the appliance.
> reboot -warm
-
-
Add the other three nodes to the cluster.
-
Log on to cluster IP address.
-
Add the second node to the cluster.
> add cluster node 1 10.102.33.187 -backplane 1/1/1 -
Add the third node to the cluster.
> add cluster node 2 10.102.33.188 -backplane 2/1/1 -
Add the fourth node to the cluster.
> add cluster node 3 10.102.33.189 -backplane 3/1/1
-
-
Join the added nodes to the cluster. This step is not applicable for the first node.
-
Log on to each newly added node.
-
Join the node to the cluster.
> join cluster -clip 10.102.33.185 -password nsroot -
Save the configuration.
> save ns config -
Warm reboot the appliance.
> reboot -warm
-
-
Configure the Citrix ADC cluster through the cluster IP address.
// Enable load balancing feature
> enable ns feature lb// Add a load balancing virtual server
> add lb vserver first_lbvserver http .... .... -
Configure any one of the following (ECMP, cluster LA, or Linkset) traffic distribution mechanisms for the cluster.
ECMP
-
Log on to the cluster IP address.
-
Enable the OSPF routing protocol.
> enable ns feature ospf -
Add a VLAN.
> add vlan 97 -
Bind the interfaces of the cluster nodes to the VLAN.
> bind vlan 97 -ifnum 0/1/4 1/1/4 2/1/4 3/1/4 -
Add a spotted SNIP on each node and enable dynamic routing on it.
> add ns ip 1.1.1.10 255.255.255.0 -ownerNode 0 -dynamicRouting ENABLED > add ns ip 1.1.1.11 255.255.255.0 -ownerNode 1 -dynamicRouting ENABLED > add ns ip 1.1.1.12 255.255.255.0 -ownerNode 2 -dynamicRouting ENABLED > add ns ip 1.1.1.13 255.255.255.0 -ownerNode 3 -dynamicRouting ENABLED -
Bind one of the SNIP addresses to the VLAN.
> bind vlan 97 -ipAddress 1.1.1.10 255.255.255.0 -
Configure the routing protocol on ZebOS by using the VTYSH shell.
Static cluster LA
-
Log on to the cluster IP address.
-
Add a cluster LA channel.
> add channel CLA/1 -speed 1000 -
Bind the interfaces to the cluster LA channel.
> bind channel CLA/1 0/1/5 1/1/5 2/1/5 3/1/5 -
Perform an equivalent configuration on the switch.
Dynamic cluster LA
-
Log on to the cluster IP address.
-
Add the interfaces to the cluster LA channel.
> set interface 0/1/5 -lacpmode active -lacpkey 5 -lagtype cluster > set interface 1/1/5 -lacpmode active -lacpkey 5 -lagtype cluster > set interface 2/1/5 -lacpmode active -lacpkey 5 -lagtype cluster > set interface 3/1/5 -lacpmode active -lacpkey 5 -lagtype cluster -
Perform an equivalent configuration on the switch.
Linksets. Assume that the node with nodeId 3 is not connected to the switch. You must configure a linkset so that the unconnected node can use the other node interfaces to communicate with the switch.
-
-
Log on to the cluster IP address.
-
Add a linkset.
> add linkset LS/1 -
Bind the connected interfaces to the linkset.
> bind linkset LS/1 -ifnum 0/1/6 1/1/6 2/1/6
-
-
-
Update the state of the cluster nodes to ACTIVE.
> set cluster node 0 -state ACTIVE > set cluster node 1 -state ACTIVE > set cluster node 2 -state ACTIVE > set cluster node 3 -state ACTIVE
