Sample cluster configurations

The following example can be used to configure a four-node cluster with ECMP , cluster LA, or Linksets.

1. Create the cluster.

   • Log on to 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
     

2. 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
     

3. 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
     

4. 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
       ....
       ....
   

5. 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 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 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 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.

     1. Log on to the cluster IP address.

     2. Add a linkset.

        > add linkset LS/1
        

     3. Bind the connected interfaces to the linkset.

        > bind linkset LS/1 -ifnum 0/1/6 1/1/6 2/1/6
        

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
