Configuring Distributed Ethernet Fabrics using vLAG
In order to deploy Distributed Ethernet Fabrics using vLAG, create a port-channel interface on the
RBridges that are to be connected. Then add the member interfaces to the port-channel and bring them
online. Configure switchport and add the VLANs that are to be allowed over the port-channel. After the
port-channels on all the RBridges are online, the vLAG forms automatically on the RBridge that
connects to multiple nodes on the other VCS cluster. In the deployment topology shown in
Distributed Ethernet Fabrics using vLAG
on page 163, the vLAG forms on the RBridges that are part of
port-channel Po1 in Data-Centers 1 and 2 that forms VCS 1.
This configuration needs to be applied on RBridges that connect the two VCS instances. Perform the
following task in global configuration mode.
1. Create a port-channel interface on all RBridges that are directly connected to RBridges in other VCS
instances.
NOTE
In logical chassis cluster mode, the port-channel is created only from the principal node and is
applied globally.
switch(config)# interface port-channel 300
2. Verify that the port-channel is created correctly by using the show running-config command.
switch(config-Port-channel-300)# do show running-config interface port-channel 300
interface Port-channel 300
vlag ignore-split
shutdown
3. Configure the port-channel interface for the switchport trunk and add the VLANs to be allowed on the
trunk interface by using the switchport command.
switch(config-Port-channel-300)# switchport
switch(config-Port-channel-300)# switchport mode trunk
switch(config-Port-channel-300)# switchport trunk allowed vlan all
4. Verify the port-channel interface configuration by using the show running-config command.
switch(config-Port-channel-300)# do show running-config interface Port-channel 300
interface Port-channel 300
vlag ignore-split
switchport
switchport mode trunk
switchport trunk allowed vlan all
