This TOI describes a feature allowing packets that do not match any VLAN translations to be dropped from a port. This can be useful to drop selective Q-in-Q packets that do not receive a VLAN. The Configuration section details CLI commands used to configure the feature.

This feature allows transport of multicast frames to an endpoint across an IP network by tunneling them through MPLSoGRE or MPLSoGUE. The tunneling of multicast frames is achieved with a traffic policy applied on the ingress interface which will match on all packets destined to a multicast IP address and redirect that traffic to a MoG nexthop group. The traffic policy will also specify “forced routing” in order to set the fwd_layer_index to 1 so that the L2 header is removed before encapsulation.

This feature allows encapsulating (and decapsulating) L2 traffic from a given interface or subinterface over a GRE tunnel. An MPLS label is added to identify the ingress interface (similar to MPLS pseudowires) and the GRE tunnel is used to transport the packets to a remote endpoint.

This feature provides a CLI command showing the list of mac addresses that could not be learned due to hash collision in the hardware table. A hash collision occurs when two or more distinct pieces of data map to the same entry ( or slot ) in the hardware table. It can happen when the hash function used to calculate the index for a given mac address results in the already occupied index, resulting in the failure of inserting the later mac address to the hardware table.
