Hi,

is there a way to check the CAPWAP Tunnel Status of all connected APs ?

Currently i do only know the AP Availability Report which show the tunnel status with green / brown color.

But i fear that if the AP looses the Tunnel for a short period of time or Tunnel is flapping - the report is to slow to show that. Also i need to know how long is the tunnel active! How many Tunnel up/downs are occuring.

It will be also interessting to see some counters regarding Tunnel status - like RX / TX Tunnel Probe packet (i hope they exists - i do not know exactly) or any other.

Any hints for me ?

The "active APs" report has the information for tunnel uptime.
I don't think that the other information is shown in a report.

Hi Ronald,

i am looking for a CLI Command because i think this is easier to check (for several APs) and the information is getting directer and faster than via a web-report.

I expect snmp is the best way to check that.
APs are reported as interfaces. Interface down means ap not connected.

There should be also OID for the tunel duration

Hi Pala,

is there no "debug" command to check and investigate tunnel issues (like on a firewall to check VPN tunnel status) ?

I'm not sure about the CLI commands, but there is a Tunnel alarm OID apTunnelAlarm=1.3.6.1.4.1.4329.15.3.19.4

You can also probably create an alarm in netsight based on RU session manager syslog events, if you just want to see when a backup tunnel is activated e.g.

"RU Session Manager Wireless AP activated backup tunnel"

Here is the link to the Controller documentation.  You can find the CLI guide for your respective controller under the software guides:

We have a script, that greps the syslog file and counts the session poll disconnects (tunnel down) messages. Then we manually check APs that have more than 20 disconnects per day. 

Oct 12 01:01:13 192.168.1.9 events: RU Session Manager Wireless AP session poll disconnect Wireless AP session timed out. (AP SN 12345678910 AP NAME xyz AP IP 192.168.15.115 timeout 45 secs (active tunnel)) 2

Oct 12 01:01:21 192.168.1.10 events: RU Session Manager Wireless AP session poll disconnect Wireless AP session timed out. (AP SN 12345678910 AP NAME xyz AP IP 192.168.15.115 timeout 60 secs (backup tunnel)) 2

Would you be willing to share the script? :-)

Hello Joshua,

I've asked the responsible colleagues. They use syslog-ng and it's possible to define filters in syslog-ng and create specific actions when these filters apply.

We use the following filter and write into MySQL database:


filter f_wlan_session_poll {


   message('session poll disconnect')


;};
