In EVPN VXLAN context, binding a VRF to a VNI usually consumes a dynamic VLAN as shown in the following sample CLI configuration. The usable range of dynamic VLANs is from 1 to 4094, which is also shared by other features such as internal VLANs. The document describes the extended VLAN support for EVPN VXLAN, which increases the number of usable dynamic VLANs. The extended VLAN range is from 4101 to 8191.

This feature enables IPv6 neighbor discovery (ND) proxies for IPv6 subnets on routed ports, L3 subinterfaces, and VLAN interfaces. IPv6 ND Proxy on VLAN interfaces support requires additional TCAM profile configuration. When enabling IPv6 ND proxy, all IPv6 ND Neighbor Solicitation (NS) packets will be trapped to the control plane instead of being forwarded. In response, IPv6 ND Neighbor Advertisement (NA) packets with the corresponding interface router MACs will be sent back.

Storm control enables traffic policing on floods of packets on L2 switching networks. The documentation describes

4.25.2F introduces storm control with packet per second support in the platforms listed below. TOI describing the
