Hi Everyone,

By default GRE type will be zero in IAP...what should be the correct value ? What if it has non zero value in GRE type? Can we have any value there?

Please clarifye on my above queries as I am totally confused

Thank you in advance..

Re: query on gre type on IAP

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 :

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


Thank you
