Hello,
I make a new thread to be more readable for community.
We have 4 APs, grouped in a virtual controller.
We want to make a guest wifi with a mobility controller.
APs are in a remote site, and mobility controller is in the main office.
Remote and main sites are linked by an IPSEC VPN.
GRE tunnel seems can't mount.
it seems that the mtu is incorrect.
Virtual Controller# show ap debug driver-config | inc MTU
SAP MTU 1500 bytes
RAP MTU 1300 bytes
SAP MTU 1500 bytes
RAP MTU 1300 bytes
I saw this : Airheads Community
I can change mtu to 1200.
Done on an AP but this seems to change nothing.
I'm not in remote or campus mode.
AP-505, mobility controller 7010.
How can i change the MTU to make GRE tunnel working?
Regards.
