Tunnel End Points

When adding a tunnel endpoint in the Tunnels Library, you are provided with two options:

■   GigaVUE

The GigaVUE option lists all the IP interfaces available on the GigaVUE H Series nodes that are connected to the GigaVUE‑FM.

■   Other

This option gives users the option to add a new IP interface that may not be listed in the GigaVUE Tunnels Library. G-Series tunnel endpoints are not auto-discovered by the Tunnels Library. So use the Other option to add this tunnel.

Creating a GigaSMART tunnel requires configuration on both the sending and receiving ends:

Sending End of Tunnel

Receiving End of Tunnel

When you provision a vMap for a GigaVUE-VM node through GigaVUE‑FM, in addition to selecting the virtual traffic to be forwarded, you also specify the destination and source leader in a bidirectional clock relationship (formerly master) for traffic to be tunneled with the following settings:

■   Tunnel Destination IP — The IP address of the tunneled network port on the receiving end of the tunnel for L2GRE. For GMIP, ERSPAN: The IP address of the IP interface on the H Series device with GigaSMART (ERSPAN is only supported for VMware).
■   Tunnel Destination Port — The listening UDP port at the destination end of the GigaSMART tunnel for GMIP only. This should be the port that is configured to receive traffic from the GigaVUE-VMs.
■   Tunnel Source Port — The port on the GigaVUE-VM from which mirrored traffic is originating. Enter 1 if this is not expected to be used.

The receiving end of the tunnel should be configured as follows:

■   Configure a Network Tunneled port with an IP address, subnet mask, and default gateway. The IP address must match the destination IP address specified at the sending end of the tunnel.
■   Create a GigaSMART operation with a tunnel decapsulation component. The Decapsulation settings include the same listening UDP port you specified as the destination port at the sending end of the tunnel.
■   Bind the GigaSMART operation to the Network Tunneled port as part of a map that distributes arriving traffic to local tool ports for analysis with local tools.
