Default EVC Configuration
No EFPs are configured. No service instances or bridge domains are configured.
Configuration Guidelines
• You can configure 4000 bridge domains on the ME 3600X switch.
• On the ME 3800X switch, the number of bridge domains that you can configure depends on the
license that is installed on the switch:
– The metro services licenses support 4000 bridge domains.
– The metro IP services licenses support 2000 bridge domains.
– The metro aggregation services license supports 4000 bridge domain and the scaled version
supports 8000 bridge domains.
• All licenses support a maximum of 64 EFPs per bridge domain.
• You can configure a service instance only on trunk ports with no allowed VLANs. Any other
configuration is not allowed. To configure a service instance on an interface, these commands are
prerequisites:
Switch (config)# interface gigabitethernet0/2
Switch (config-if)# switchport mode trunk
Switch (config-if)# switchport allowed vlan none
• After you have configured a service instance on an interface, switchport commands are not allowed
on that interface.
• You must configure encapsulation on a service instance before configuring bridge domain.
• When you configure aa bridge domain between 1 and 4094, IGMP snooping is automatically
disabled on the VLAN.
• The native VLAN ID specified in switchport trunk native vlan-id is not used by EVC.
• ISL trunk encapsulation is not supported.
• When an EFP encapsulation is the default (matching or allowing all ingress frames), you cannot
configure any other encapsulation on an EFP on the same port and bridge-domain as the default
encapsulation. There can be only one default encapsulation per port.
