Avaya Switch is not creating connections with WLC

Issue/Introduction

Avaya VSP-4850GTS-PWR+ with firmware (7.1.6.0) not creating connections between Switch (WLC) and AP.

We have several Avaya Switches acting as WLC. The difference here with Cisco is that the AP's are not discovered via WLC as they are not managed the same way as Cisco. Therefore the AP's are discovered via SNMPv3.

 

The problem comes once the WLC and the AP's are discovered and modeled and the connections between them need to be modeled.

 

Avaya Switches (acting as WLC's) can have 2 different type of operating systems. One is VOSS the other is ERS. On ERS software, the AP's are establishing the connections just fine. On the VOSS system it does not.

 

The VOSS devices:

 

Avaya Switch (acting as WLC) and running VOSS.

 

1.3.6.1.2.1.1.1.0             , OctetString , VSP-4850GTS-PWR+ (7.1.6.0)  HW Base: VSP 4850
1.3.6.1.2.1.1.2.0             , ObjectID    , 1.3.6.1.4.1.2272.203

 

 

 

When checking the autodiscovery debug we can see that Spectrum fails to read the bridge table for the AVAYA Switch:

 

 

 

Now, for ERS devices, working:

 

 

The AVAYA switches are certified in Spectrum, though it looks the MIB's are kind of old.

 

 

Environment

Release : 20.2

Component : Spectrum Certification

Cause

For Avaya VSP-4850GTS-PWR+ with firmware (7.1.6.0) the bridge table information is stored in the Rapid-City Mib.

Resolution

With updated firmware, the Avaya 4850 Bridge table is only available in the Rapid-City mib.

Opened feature request F113221 to get this implemented in Spectrum.

 

Additional Information

Unless LLDP can be implemented on the AP´s and Avaya Switch, the connections will have to be made manually until feature request F113221 is complete in a future Spectrum release.
