APIC-EM 1.6.2 EasyQoS Avaya Telephony

Fellow Networkers,

 

EasyQoS leverages feedback from CDP to populate ACLs with Cisco IP Phone IP addresses;  LLDP feedback is ignored.   Bespoke applications encompassing the Avaya RTP range of ports is only processed on NBAR supporting products; therefore, I’m left with trusting inbound QoS and reclassifying – in software – on the ISR/ASR.

 

The default range of RTP ports used by Avaya is UDP 2408 – 3028.  I am trying to quantity the negative impact on Switch TCAM before bench testing.  Pointers would be appreciated.

 

Unfortunately, Cisco TAC have bled the BU dry and are unable to offer a solution other than getting Avaya switches/gatekeepers to post northbound REST API calls in response to H323 signalling changes.

 

For instance, is there any mileage running a tcl script to process the consequences of a lldp neighbour change and posting the outcome northbound?  Could we use the information gathered by Cisco Prime to trigger a Rest API to APIC-EM?  Any ideas would be most welcome.

 

Thanks in anticipation
