How to Configure EVC-Lite

How to Configure EVC-Lite
Create a VLAN:
Step 1
Switch# configure terminal
Enter configuration commands, one per line.
Switch(config)# vlan vlan-ID
Switch(config-vlan)# exit
Configure the VLAN as an EVC-Lite VLAN:
Step 2
Switch(config)# vlan configuration vlan_ID
Switch(config-vlan-config)# evc-lite
Switch(config-vlan-config)# exit
Associate the EVC-Lite VLAN to an interface:
Step 3
Switch(config)# interface gigabitethernet slot/port
Switch(config-if)# switchport mode trunk
Switch(config-if)# switchport trunk allowed vlan vlan_ID
Enable the interface with bridge-domain {0|1}:
Step 4
Switch(config-if)#?
Interface configuration commands:

-----
evc-lite

Switch(config-if)# evc-lite bridge-domain bridge-domain
Switch(config-if)# exit
This sequence creates an EVC-Lite VLAN and associates it to an interface. The same VLAN can be
associated with multiple interfaces, although each interface can have only one bridge-domain. On a
Catalyst 4500 series switch, we can have two BDs (0 and 1). Because each BD supports 4K VLAN's, we
can support 8K VLANs. An EVC-Lite VLAN can be associated with the BD 0 and 1 interfaces. However,
traffic flowing on this VLAN under BD 1 will never flow under BD 0 and vice-versa.
This example shows how to configure VLAN 10 as EVC-Lite, enable interface GigabitEthernet 7/1 in
BD 1, and display configured EVC-Lite VLANs and ports in BD 1:
Switch(config)# vlan configuration 10
Switch(config-vlan-config)# evc-lite
Switch(config-vlan-config)# exit
Switch# show running-config | begin vlan configuration
vlan configuration 10
Switch(config)# interface gigabitEthernet 7/1
Switch(config-if)# switchport mode trunk
Switch(config-if)# evc-lite bridge-domain 1
Switch(config-if)# exit
Switch# show run interface gigabitEthernet 7/1
