Error: There is a problem with your upstream device table

Issue: Error: There is a problem with your upstream device table

 

I'm seeing the following error:

There is a problem with your upstream device table. Contact AirWave Technical Support...

What does it mean and how can I fix it?

WHAT'S HAPPENING
* * * * * * * * * * * * * * * *
This happens when CDP repeatedly flip flops about the upstream/downstream relationship of two devices. Each time we see the relationship change, we update the upstream_device table. If this happens repeatedly, the left_ and right_visit numbers can grow very large causing the error.

SOLUTION
* * * * * * * * *
It would be helpful to us if you could send us the output from the following command:

# dbc "select a.id, a.type, a.name, u.left_visit, u.right_visit from ap a, upstream_device u where a.id = u.ap_id order by u.right_visit desc limit 15"

To clean up the upstream_device table you can run the following commands:

# disable_amp
# /usr/local/airwave/bin/compact_upstream_device_table
# enable_amp

If the error message appears again, you can repeat these steps.

We expect to have the error fixed in an upcoming release.
