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 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. |
