Configure GigaSMART Operation for Layer 2 GRE

To access GigaSMART within GigaVUE‑FM, access a device that has been added to GigaVUE‑FM from the GigaVUE‑FM interface. GigaSMART appears in the navigation pane of the device view on supported devices. Refer to Access GigaSMART from GigaVUE‑FM for details.

To configure the L2GRE encapsulation/decapsulation types and options, use the GigaSMART Operations (GSOP) page:

1.   From the device view, select GigaSMART > GigaSMART Operations (GSOP) > GigaSMART Operation.
2. Click New.
3. On the GigaSMART Operations page, do the following:
a. Type an alias in the Alias field.
b. In the GigaSMART Groups field, select the gsgroup for this operation.
c. In the GigaSMART Operations (GSOP) field, select either Tunnel Decapsulation or Tunnel Encapsulation from the drop-down list, depending on whether you want decapsulation or encapsulation.
d. Select L2GRE, and then enter options in the fields that display.
4. Click Save.

In this example, an IP interface is configured on the tool port. A GigaSMART operation for tunnel encapsulation is configured to encapsulate the filtered packets. A map is configured that uses the L2GRE tunnel encapsulation GigaSMART operation, which sends packets from the remote site over the Internet to the main office using the IP interface associated with a tool port. Staring with software version 5.4 GigaSMART L2GRE Tunnel Encapsulation provides support for IPv6 with load-balancing.

In this example, an IP interface is configured on the network port. A GigaSMART operation for tunnel decapsulation is configured to decapsulate the filtered packets. A map is configured that uses the L2GRE tunnel decapsulation GigaSMART operation, which receives packets from the remote site over the Internet to the main office using the IP interface associated with a tool port and then forwards packets over the tool port. Staring with software version 5.4 GigaSMART L2GRE Tunnel Decapsulation provides support for IPv6 with load-balancing.
