Re: whAT SHOULD BE THE PORT STATUS ACCESS OR TRUNK FOR L2 AND L3 GRE TUNNELING

Neither really, however, if you create a layer 2 GRE tunnel you can pass VLANs over it. The controller will not show the status as a trunk though and likewise will not show a layer 3 GRE tunnel as access.

 

Here's what they look like and notice no reference to access or trunk:

 

L2 GRE with multiple VLANS

(Aruba7010) #show interface tunnel 999

Tunnel 999 is up line protocol is up
Description: Tunnel Interface
Source 172.16.10.11
Destination 172.16.10.10
Tunnel mtu is set to 1100
Tunnel is a Layer2 GRE TUNNEL
Tunnel is Trusted
Inter Tunnel Flooding is enabled
Tunnel keepalive is disabled
Keepalive type is Default
tunnel vlan 1,10-11

 

L3 GRE 

(Aruba7010) #show interface tunnel 998

Tunnel 998 is up line protocol is up
Description: Tunnel Interface
Internet address is 172.16.99.12 255.255.255.255
Source 172.16.10.11
Destination 172.16.10.10
Tunnel mtu is set to 1100
Tunnel is an IP GRE TUNNEL
Tunnel is Trusted
Inter Tunnel Flooding is enabled
Tunnel keepalive is disabled
Keepalive type is Default
