EVC On Port-Channel

An EtherChannel bundles individual Ethernet links into a single logical link that provides the aggregate bandwidth of up to eight physical links.The EVC EtherChannel feature provides support for EtherChannels on Ethernet Virtual Connection Services (EVCS) service instances.

The EVC EtherChannel feature supports MPBE, local connect, and xconnect service types.

Load balancing is accomplished on a Ethernet flow point (EFP) basis where a number of EFPs exclusively pass traffic through member links. In a default load balancing, you have no control over how the EFPs are grouped together, and sometimes the EFP grouping may not be ideal. To avoid this, use manual load balancing to control the EFP grouping.

Restrictions for EVC EtherChannel

The following restrictions apply to EVC EtherChannel:

•Bridge-domains, EVCs, and IP subinterfaces are allowed over the port-channel interface and the main interface.

•If you configure a physical port as part of a channel group, you cannot configure EVCs under that physical port.

•If port-channel is configured on an MPLS core, the encapsulation ID should be the same as the bridge domain.

•A physical port that is part of an EVC port-channel cannot have EVC configuration.

•Statically configuring port-channel membership with LACP is not supported.

•You can apply QoS policies under EVCs on a port-channel.

•You cannot use the police percent commands on EVC port-channels in flat policy-maps or in parent of HQoS policy-maps.
