Troubleshooting LWAPP packets

Question

How do I access the LWAPP packets in order to troubleshoot ZD /AP connectivity issues?

Unfortunately, no, Ruckus does not have LWAPP exchange message analysis.

ZD Debug with 'Access Points' component will show some AP/ZD communication

exchange but does not decrypt LWAPP.

A Ruckus TSE can enable tcpdump from AP shell mode to see LWAPP, but this

is not something available to users, without opening a Tech Support ticket.

Hi Michael,

Aren't the LWAPP packets within the tunnel?  I know in the Cisco WLC-5508 you have to troubleshoot CAPWAP and LWAPP by enabling the LWAPP log messages within the controller.   Is there a way to access the LWAPP messages within the ZD's log messages to troubleshoot the connection between the ZD and AP in more detail?

Thanks for your help

A switch port trace of either ZD or AP port will provide all the necessary information.

If trying to bring up new APs, confirm you have routing between the AP and ZD,

and you may need a DHCP option 43 or DNS 'zonedirector' hostname defined

with your ZD's IP address.  If there is network connectivity but AP isn't seen trying

to connect, you can also SSH to your AP and give the CLI command 'set director

ip a.b.c.d' where a.b.c.d is your ZD's IP address, followed by 'reboot'.  After the

reboot, the AP will send LWAPP discover to your ZD's a.b.c.d IP address.

If all else fails, open a ticket with Tech Support for further troubleshooting/assistance.
