Common interfaces for client and server and dedicated interfaces for backplane

January 6, 2019
Contributed by:  S C

This is a one-arm deployment of the NetScaler cluster. In this deployment, the client and server networks use the same interfaces to communicate with the cluster. The cluster backplane uses dedicated interfaces for inter-node communication.

  • NS0 - nodeId: 0, NSIP: 10.102.29.60

  • NS1 - nodeId: 1, NSIP: 10.102.29.70

  • NS2 - nodeId: 2, NSIP: 10.102.29.80

    To deploy a cluster with a common interface for the client and server and a different interface for the cluster backplane

    1. Create a cluster of nodes NS0, NS1, and NS2.

    2. Log on to the first node that you want to add to the cluster and do the following:

      create cluster instance 1
add cluster node 0 10.102.29.60 -state ACTIVE -backplane 0/1/1
enable cluster instance 1
add ns ip 10.102.29.61 255.255.255.255 -type CLIP
save ns config
reboot -warm

    3. Log on to the cluster IP address and do the following:

      add cluster node 1 10.102.29.70 -state ACTIVE -backplane 1/1/1
add cluster node 2 10.102.29.80 -state ACTIVE -backplane 2/1/1

    4. Log on to the nodes 10.102.29.70 and 10.102.29.80 to join the nodes to the cluster.

      join cluster -clip 10.102.29.61 -password nsroot
save ns config
reboot -warm

    As seen in the above commands the interfaces 0/1/1, 1/1/1, and 2/1/1 are configured as the backplane interfaces of the three cluster nodes.

  1. On the cluster IP address, create VLANs for the backplane interfaces and for the client and server interfaces.

    //For the backplane interfaces
add vlan 10
bind vlan 10 0/1/1 1/1/1 2/1/1

//For the interfaces that are connected to the client and server networks.
add vlan 20
bind vlan 20 0/1/2 1/1/2 2/1/2

  2. On the switch, create VLANs for the interfaces corresponding to the backplane interfaces and the client and server interfaces. The following sample configurations are provided for the Cisco® Nexus 7000 C7010 Release 5.2(1) switch. Similar configurations must be performed on other switches.

    //For the backplane interfaces. Repeat for each interface...
interface Ethernet2/47
switchport access vlan 100
switchport mode access
end

//For the interfaces connected to the client and server networks. Repeat for each interface...
interface Ethernet2/47
switchport access vlan 200
switchport mode access
end
