You should leave it as 0 , unless the endpoint device you are trying to build the GRE tunnel to requires an specific value

 

Here one example from the IAP Guide :

 

Aruba Instant 6.2.1.0-3.4 User Guide.pdf - Adobe Reader_2013-07-29_15-51-32.png

 

 

This should help you :

This is on a controller:

(controller) #show  ap debug datapath ap-name test-ap

Datapath Parameters Table
-------------------------
essid            encr-alg        client-vlan-id  tunnel-id  gre-type  deny-bcast  num-clients
-----            --------        --------------  ---------  --------  ----------  -----------
test-ssid          WPA2 8021X AES  702    0x122af    0x8240    disable          0
