The feature allows to create a named TC to DSCP mapping that can be applied on an interface.DSCP of routed packets egressing out of the interface will be rewritten according to the map.

EVPN route advertisements carry RD and RT. RD (Route Distinguisher) : prepend to the tenant’s IP Prefix or MAC address to make it globally unique. RT (Route Target) : a BGP extended community used to tag the EVPN route.  The EVPN import policy is chosen to select what is the target tenant VRF is imported from the global EVPN table.

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. Starting from 4.32.1F, forwarding of MACsec EAPoL frames is also supported on a per interface basis on certain platforms.

Lanz Mirroring feature allows users to automatically mirror traffic queued as a result of congestion to either CPU or a different interface.

IP traceroute and path MTU (PMTU) discovery both require that routers send ICMP reply messages to the host that invokes each network function. When the route to the destination host traverses an MPLS label-switched path (LSP), the label switching routers (LSRs) will also need to send ICMP reply messages to the originating host.
