GRE Striping and AP Failover

I know there are lots of posts on this but I was wondering if somebody could clear up how GRE striping should be configured in an AP failover scenario.

 

The following configuration is being used:

 

Master controller - 10.10.10.10

Local controller - 10.10.10.11

 

Both controllers have the GRE LMS LACP mapping set as below:

 

ap-lacp-striping-ip
aplacp-enable
striping-ip 10.10.10.13 lms 10.10.10.10
!

 

APs are in an AP group which has an AP system-profile configured as below:

 

ap system-profile "Master_Hosted"
lms-ip 10.10.10.10
bkup-lms-ip 10.10.10.11
lms-preemption
!

 

and also HA fast failover is configured as below:

 

ha group-profile "HA_Group1"
preemption
controller 10.10.10.10 role dual
controller 10.10.10.11 role dual
!

 

Both controllers show the AP as up with striping enabled (the s flag is there on 'show ap database long' from both controllers).

Connections work fine on the master controller but when I failover the AP to the local controller, the 'a' radio works fine but the 'b/g' radio doesn't allow connections.

 

I have been through numerous configurations with GRE striping to LMS IP but can't get this to work. 

Thanks

Re: GRE Striping and AP Failover

Does each controller have a unique striping IP (x+1)?

Re: GRE Striping and AP Failover

Hi Tim,

 

I've played with multiple configurations but originally each controller had its own striping IP as below:

 

striping-ip 10.10.10.13 lms 10.10.10.10

striping-ip 10.10.10.14 lms 10.10.10.11

 

Thanks
