Environment : This article applies to aruba controllers running least 6.1.2.4 and above.
1. Tunneled node not coming up. It gets stuck in " in progress":
(ArubaS3500) #show tunneled-node state
Tunneled Node State
-------------------
IP MAC Port state vlan tunnel inactive-time
------------ ----------------- ------- ----------- ---- ------ -------------
10.20.20.125 00:1a:1e:10:fb:c0 GE0/0/1 in-progress 0221 4094 0000
2. we can ping to the controller IP from the switch.
3. Switch port is up.
4. port vlan exists on the controller and is up and up.
Cause: Sometime, on the controller we have the tunneled-node address configured. If yes, we need to set it back to 0.
Solution :
Configure the following on the controller:
tunneled-node-address 0.0.0.0
All configured correctly and ip connectivity verified, sometimes the tunneled node still does'nt come up and gets stuck at "in-progress".
In such cases, we need to check if tunneled node config also exists on the controller. If it does, we need to reset it to 0 by:
# config t
# tunneled-node-address 0.0.0.0
