IPX Protocol and LLQ for VOIP

[dvaggalis]

I have LLQ setup for VOIP. I would like to add IPX, what effect does this have on LLQ.

[jbayuka]

I guess the LLQ will work as configured and the IPX traffic will be treated as default traffic and will be given the same treatment defined for the default class.

I spoke with TAC, gave the same reply.

Hi Dennis,

Thanks for writing me for the question. Yes in the VoIP solution, the traffic that doesn't fall into one of the class-map that you have configured, will fall into the class-default. I can point to a document that tells about it.

class class-default

fair-queue 16

queue-limit 20

The default class has these characteristics: 16 dynamic queues are reserved for traffic that does not meet the match criteria of other classes whose policy is defined by the policy map called policy1, and a maximum of 20 packets per queue are enqueued before tail drop is enacted to handle additional packets.

Thanks
