Tagging traffic with a drop precedence is a method that can be used to differentiate traffic flows over a given

EOS supports the ability to match on a single VLAN tag (example: encapsulation dot1q vlan 10)  or a VLAN tag pair (example: encapsulation dot1q vlan 10 inner 20) to map matching packets to an interface. In this case, the encapsulation string is considered consumed by the mapped interface before forwarding, which means that the tags are effectively removed from the incoming packet for the purposes of any downstream forwarding.

L2 protocol packets - LLDP, LACP and STP are trapped to the CPU by default. This feature allows for disabling the per protocol trap on a given set of interfaces.

Allows the user to configure explicit QoS trust settings viz. trust mode, default cos and default dscp on subinterfaces, which may or may not be the same as the parent interface.

Storm control enables traffic policing on floods of packets on L2 switching networks. Support was enabled for Front panel ports and Lag in eos-4-25-2f with storm-control-speed-rate-support. Now, storm control will be supported per subinterfaces( both ethernet and port-channel). Scale of subinterfaces is 4095. 

Subinterfaces divide a single ethernet or port channel interface into multiple logical L2 or L3 interfaces based on the 802.1q or 802.1ad tags of incoming traffic. Subinterfaces are commonly used in the L2/L3 boundary device, but they can also be used to isolate traffic with 802.1q tags between L3 peers by assigning subinterfaces to different VRFs or different L2 bridging domains.

L3 subinterface counters do not count GRE terminated (decap) packets and other tunnel types packets such as decap
