Auto port reset / ap reset

Aviv_Kedem — Thu, 05 Dec 2019 16:41:07 GMT

Hello guys,

Deployment with many branches ap7532 (5.9.0-5.9.4.1) with VC in any branch.

Once every few months the aps are loosing the ge1 links with switches (several models of cisco Catalyst).

When it’s happening, the ports are in down state, without physical errors. Electrical reset to AP

solves the problem temporarily. There is no crash logs on APS after it’s happening.

I’m looking for some way to make auto ge1 port reset on AP or AP auto reload in case of loosing ge1 link.

Any suggestions will be appreciated.

Thanks

Aviv

Hi Aviv,

As usual (with Cisco) everyone around should properly handle all the issues. Cisco box is always configured properly, no way to improve )
In this particular case I would recommend to track a link status on cisco side using CDP/LLDP to build a list of ports (or use static list of ports). Than parse link loss (or CDP neighbor loss) from syslog and react with ANSIBLE (or similar tool) with PoE recycle on specific port.

From AP perspective we have following options related to link loss - nothing make a sense, unfortunately..

ap76X2-XXXX#help search loss
Found 8 references for "loss"
