Step 2: Configure the MCT VLAN, MCT Session VLAN, Recommended MCT Keep-Alive VLAN, and ICL Forwarding Delay

To create the recommended MCT keep-alive VLAN and MCT session VLAN for RUCKUS-1 and RUCKUS-2 devices in the topology of Basic MCT configuration, enter the following commands.

  1. Create an MCT keep-alive VLAN by adding the tagged ports to the VLAN. 
    RUCKUS-1# configure terminal
RUCKUS-1(config)# vlan 3001 name MCT-keep-alive 
RUCKUS-1(config-vlan-3001)# tagged ethernet 1/2/1
RUCKUS-1(config-vlan-3001)# exit

    RUCKUS-2# configure terminal
RUCKUS-2(config)# vlan 3001 name MCT-keep-alive 
RUCKUS-2(config-vlan-3001)# tagged ethernet 1/2/1
RUCKUS-2(config-vlan-3001)# exit
  2. Create a session VLAN by adding the ICL static LAG ID to the VLAN, and disable the spanning tree protocol. 
    RUCKUS-1(config)# vlan 3000 name Session-VLAN
RUCKUS-1(config-vlan-3000)# tagged lag 2
RUCKUS-1(config-vlan-3000)# no spanning-tree 802-1w
    RUCKUS-2(config)# vlan 3000 name Session-VLAN
RUCKUS-2(config-vlan-3000)# tagged lag 2
RUCKUS-2(config-vlan-3000)# no spanning-tree 802-1w
  3. Create a router interface with session VLAN ID, and assign an IP address to the router interface. 
    RUCKUS-1(config)# interface ve 3000
RUCKUS-1(config-vif-3000)# ip address 10.1.1.3/24

    RUCKUS-2(config)#interface ve 3000
RUCKUS-2(config-vif-3000)# ip address 10.1.1.2/24
  4. (Optional) Configure a delay in seconds to wait after the ICL link comes up before regular traffic can be transmitted. During the delay, only BPDU traffic is forwarded. The default is 0. The valid range is 0 through 30.
    RUCKUS-1(config)# cluster Building-A 200 <-creates cluster
                                        enters cluster
                                        config mode
RUCKUS-1(config-cluster-Building-A)# icl-fwd-delay 3
RUCKUS-1(config-cluster-Building-A)# exit
RUCKUS-1(config)#
    RUCKUS-2(config)# cluster Building-A 200
RUCKUS-2(config-cluster-Building-A)# icl-fwd-delay 3
RUCKUS-2(config-cluster-Building-A)# exit
RUCKUS-2(config)#
  5. (Optional) Configure a delay in seconds to keep dynamic CCEP LAGs on a CCP peer in blocking state while CCP comes up, for example, following a cluster-peer reload, ICL flap, or cluster re-deployment or undeployment.
    RUCKUS-1(config)# cluster Building-A 200
RUCKUS-1(config-cluster-Building-A)# ccep-up-delay 300
RUCKUS-1(config-cluster-Building-A)# exit
RUCKUS-1(config)# 
    RUCKUS-2(config)# cluster Building-A 200
RUCKUS-2(config-cluster-Building-A)# ccep-up-delay 300
RUCKUS-2(config-cluster-Building-A)# exit
RUCKUS-2(config)#
    Note: The delay can be set to a value from 0 through 600 seconds. The recommended setting is 300. The default setting is 0, which disables the timer.

To implicitly configure the data VLAN as an MCT VLAN and add the ICL as a tagged member of the VLAN, enter the following commands. 

RUCKUS-1(config)# vlan 10 name Data-VLAN-example
RUCKUS-1(config-vlan-10)# tagged lag 2 lag 5 to 6
RUCKUS-2(config)# vlan 10 name Data-VLAN-example
RUCKUS-2(config-vlan-10)# tagged lag 2 lag 5 to 6
