Enable Header Stripping Protocol on Ports

You can enable Header Stripping protocol on any network or hybrid ports. If you enable the Header Stripping protocol on a port, you cannot configure the VXLAN ID or L2GRE ID for that port.

To enable a Header Stripping protocol on a network or hybrid port:

  1. From the device view, go to Ports > Ports > All Ports.

  2. Select the required network or hybrid port on which you want to enable the Header Stripping protocol, and then click Edit.

  3. Under the Parameters section, from the Header Stripping Protocol drop-down list, select one of the following options:

    • None – Header stripping protocol is not enabled on the port.

    • MPLS-L3 – Port is enabled with MPLS Header Stripping protocol to strip the MPLS header from the MPLS layer 3 packets tapped on this port. Select this option if L3 MPLS traffic type only is present in network..

    • VXLAN – Port is enabled with VXLAN Header Stripping protocol to strip the VXLAN header from the VXLAN packets tapped on this port.

    • MPLS-Advanced – Enable advanced MPLS Header Stripping on the port. This functionality applies only to the GigaVUE-TA400 devices. Refer to Advanced MPLS Header Stripping for GigaVUE-TA400. This option supports the stripping of various MPLS packet formats and provides additional sub-options:

      o   IPv4 Without Options – Strips the MPLS Header from the L3 MPLS IPv4 (without options) packets. Select this option only if L3 MPLS IPv4 (without options) traffic type is present in network. IPv4 without options has a standard 20-byte header for efficient routing.
      o   IPv4 With Options – Strips the MPLS Header from the L3 MPLS IPv4 (with options) packets. Select this option only if L3 MPLS IPv4 (with options) traffic type is present in network. IPv4 with options includes additional fields (up to 60 bytes) for advanced functions like timestamping.
      o   IPv6 – Strips the MPLS header from the L3 MPLS IPv6 packets. Select this option only if L3 MPLS IPv6 traffic type is present in network. The standard IPv6 header (40 bytes) follows the MPLS label stack and contains source and destination IPv6 addresses, flow labels, and other fields.
      o   L2 Without CW/ACH – Strips the outer Ethernet and MPLS headers from the incoming L2 MPLS without Control Word(CW) or Associated Channel Header(ACH) packets. Select this option only if L2 MPLS (without CW/ACH) traffic type is present in network. L2 MPLS without CW or ACH provides a basic MPLS label-switched path for transporting Layer 2 packets without the extra control, sequencing, or signaling functionalities provided by the CW and ACH headers.
      o   L2 With CW/ACH – Strips the outer Ethernet and MPLS headers along with Control Word (CW) or Associated Channel Header(ACH) from the incoming L2 MPLS with CW or ACH packets. Select this option only if L2 MPLS (with CW/ACH) traffic type is present in network. L2 MPLS with CW ensures packet sequencing and integrity for Layer 2 frames, while ACH enables Operations, Administration, and Maintenance (OAM) transport for network monitoring and management, especially in MPLS traffic.
