GigaSMART Custom Tunnel Decapsulation

Use custom tunnel termination to terminate a custom tunnel header that is received at the network IP interface, but is not known to GigaSMART. The destination IP and MAC addresses must match the IP and MAC addresses of the network tunnel.

Refer to the “GigaSMART Custom Tunnel Decapsulation” section in the GigaVUE Fabric Management Guide for detailed information.

Custom Tunnel Termination Example

Step

Description

Command
1.    

Configure a tool type of port.

(config) # port 1/1/g1 type tool
2.  

Configure a GigaSMART group and associate it with a GigaSMART engine port.

(config) # gsgroup alias gsgp1 port-list 1/3/e1
3.  

Configure the IP interface.

(config) # ip interface alias test

(config ip interface alias test) # attach 1/1/g1

(config ip interface alias test)

# ip address 10.10.10.10 /29

(config ip interface alias test) # gw 10.10.10.1

(config ip interface alias test) # mtu 9400

(config ip interface alias test) # gsgroup add gsgp1

(config ip interface alias test) # exit
4.  

Configure the GigaSMART operation and assign it to the GigaSMART group.

(config) # gsop alias custom1 tunnel-decap type custom portsrc 200 portdst 200 port-list gsgp1
5.  

Create a map.

(config) # map alias map2

(config map alias map2) # type regular byRule

(config map alias map2) # use gsop custom1

(config map alias map2) # rule add pass protocol udp

(config map alias map2) # from 1/1/g2

(config map alias map2) # to 1/1/g1

(config map alias map2) # exit

(config) #
6.  

View the custom tunnel GigaSMART operation.

(config) # show gsop alias custom1
7.  

View the custom tunnel statistics.

(config) # show gsop stats alias custom1
