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
    RUCKUS-2(config)# vlan 3000 name Session-VLAN
RUCKUS-2(config-vlan-3000)# tagged lag 2
RUCKUS-2(config-vlan-3000)# no spanning-tree
  3. For ICX devices running a router image, add the following commands in the session VLAN configuration mode. 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. For ICX devices running a switch image, assign an IP address in the Global Configuration mode. 
    RUCKUS-1(config)# ip address 10.1.1.3/24

    RUCKUS-2(config)# ip address 10.1.1.2/24
  5. (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 mct_stack 1000 <-creates cluster
                                        enters cluster
                                        config mode
RUCKUS-1(config-cluster-mct_stack)# icl-fwd-delay 3
RUCKUS-1(config-cluster-mct_stack)# exit
RUCKUS-1(config)#
    RUCKUS-2(config)# cluster mct_stack 1000
RUCKUS-2(config-cluster-mct_stack)# icl-fwd-delay 3
RUCKUS-2(config-cluster-mct_stack)# exit
RUCKUS-2(config)#
  6. (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 mct_stack 1000
RUCKUS-1(config-cluster-mct_stack)# ccep-up-delay 300
RUCKUS-1(config-cluster-mct_stack)# exit
RUCKUS-1(config)# 
    RUCKUS-2(config)# cluster mct_stack 1000
RUCKUS-2(config-cluster-mct_stack)# ccep-up-delay 300
RUCKUS-2(config-cluster-mct_stack)# 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 MCT VLAN and add the ICL as a tagged member of the VLAN, enter the following commands. 

RUCKUS-1(config)# vlan 1000 name MCT-VLAN-example
RUCKUS-1(config-vlan-1000)# tagged ethernet 1/1/1 to 1/1/3 lag 2
RUCKUS-2(config)# vlan 1000 name MCT-VLAN-example
RUCKUS-2(config-vlan-1000)# tagged ether 1/1/1 to 1/1/2 lag 2
