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.

Storm control enables traffic policing on floods of packets on L2 switching networks. Support for counting dropped packets and bytes on interfaces where storm control metering is provisioned. Both packet and bytes count are supported and will be displayed. Drop logging on storm-control discards is also supported.

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.

User-defined TPIDs allows an arbitrary TPID (Tag Protocol Identifier) to be used with a FlexEncap specification. A TPID is used in Ethernet frames to identify the encapsulation protocol, where standard values like 0x8100 (for IEEE 802.1q VLAN tagging) and 0x88a8 (for IEEE 802.1ad Q-in-Q) are commonly used. However, some network equipment may use non-standard or legacy values such as 0x9100. This feature allows FlexEncap subinterfaces to be configured with an arbitrary TPID to allow interfacing with networking equipment that uses values besides 0x8100 and 0x88a8.
