Ethernet Virtual Connections Configuration
Restrictions
• Transparent CFM is not supported with Asymmetric EFP.
• Q-in-Q encapsulation type in the EFP is not supported. Frames with dot1q greater than value 1 is
• Trunk-EFPs usage is not supported
• 2 Tag push or pop is not supported.
• Translate option, in VLAN Translation, is not supported with asymmetric rewrite rules.
• External Loopback operations are not supported.
• Ignoring MLD reports (IPv6) is not supported
• When the encapsulation is untagged in one of the EFPs, for example if rewrite egress tag pop 1 is
• If there are different EFPs in the same BD that are carrying unicast and multicast traffic, then MAC
• Asymmetric rewrite configuration fails for the priority-tagged encapsulation.

Configuration Examples

Example for Configuring a Service Instance

Router (config)# interface gigabitethernet0/1
Router (config-if)# service instance 22 Ethernet ether
Router (config-if-srv)# encapsulation dot1q 10
Router (config-if-srv)# bridge-domain 10

Example for Encapsulation Using a VLAN Range

Router (config)# interface gigabitethernet0/1
Router (config-if)# service instance 22 Ethernet
Router (config-if-srv)# encapsulation dot1q 22-44
Router (config-if-srv)# bridge-domain 10
supported. Dot1ad is not supported.
configured on the EFP, then rewrite ingress tag pop 1 will cancel the rewrite rule and the packet is sent
without rewrites.
learning should be disabled on the multicast EFP using disable-learning command.
