VXLAN Header Stripping—Rules and Notes

Keep in mind the following rules and notes when working with VXLAN header stripping:

■   VXLAN header stripping is supported on GigaVUE‑HC1, GigaVUE‑HC2 CCv2, GigaVUE‑HC3, GigaVUE-TA40, GigaVUE-TA100, GigaVUE-TA200 devices and GigaVUE‑TA25.
■   Gigamon’s traffic intelligence processing may lead to initial packet drops.
■   On a network or hybrid port that taps the network traffic, you can enable either VXLAN header stripping or MPLS header stripping, but you cannot enable both the functionalities.
■   Network ports configured with VXLAN header stripping and MPLS header stripping functionalities cannot be part of the same map. You must create separate maps for these ports.
■   VXLAN header stripping is not supported on network ports that are part of pass-all maps.
■   VXLAN header stripping is not supported with IPv6 addresses.
■   Ingress and egress VLAN tagging is not supported.
■   VXLAN header stripping is not supported for Q-in-Q traffic.
■   You cannot enable VXLAN header stripping on a port that is part of a port-pair.
■   Reassembly of fragmented packets after VXLAN header stripping is not supported.
■   A maximum of up to 4096 dynamic VXLAN IDs are supported for VXLAN header stripping.
■   VXLAN header stripping does not work if you configure a map with any rule that includes the qualifying attributes of the VXLAN header because such rules override the traffic intelligence capability. For example, if you configure a map with pass rule as IPv4 Destination, IPv4 Source, MAC Destination, or MAC Source and the source leader in a bidirectional clock relationship (formerly master) port of the map is enabled with VXLAN header stripping, the header stripping functionality does not work.
■   VXLAN header stripping does not work if you configure a map with only drop rules and choose the Pass Traffic option so that the traffic is passed through the port when there are no matching rules. For more information, refer to the “Regular” map type in the Map Types section.
■   Following table provides the maximum number of static IP addresses that can be configured for each platform for the VXLAN header stripping functionality:
