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.

As of EOS 4.22.0F, EVPN all active multihoming is supported as a standardized redundancy solution. For effective

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 TOI describes the MAC limit per VLAN feature which can be used to limit the number of locally learned MAC addresses per VLAN.

This TOI describes a set of enhancements made to the existing Port Security: Protect Mode (PortSec-Protect) feature. Please see the existing TOI for this feature here:Port Security: Protect Mode

Compatible platforms start up in the “default” forwarding-table partition mode, which provides the ability to program up to 8K L2 addresses.

This feature provides a cli command showing the list of mac addresses which 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 failure of inserting the later mac address to the hardware table.
