Chapter 19 Configuring EVC-Lite
How to Configure EVC-Lite
Step 2 Configure the VLAN as an EVC-Lite VLAN:
Switch(config)# vlan configuration vlan_ID
Switch(config-vlan-config)# evc-lite
Switch(config-vlan-config)# exit
Step 3 Associate the EVC-Lite VLAN to an interface:
Switch(config)# interface gigabitethernet slot/port
Switch(config-if)# switchport mode trunk
Switch(config-if)# switchport trunk allowed vlan vlan_ID
Step 4 Enable the interface with bridge-domain {0|1}:
Switch(config-if)#?
Interface configuration commands:
-----
-----
evc-lite set the interface in evc-lite mode
--More--
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
evc-lite
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

interface GigabitEthernet7/1
switchport mode trunk
evc-lite bridge-domain 1
end
Switch# show evc-lite
evc-lite vlans: 10
Ports in bridge-domain 1: Gi7/1
Note Because a port channel can only accommodate member links belonging to the BD of the port-channel,
the show evc-lite command displays only the port-channel instead of all the member links.
