Qos ane hold-queue

[sherrikhan]

Gents we he default class map

ans policy configured for Cisco phone and voice my question is do we need to add hold-queue command on router in interface which connects to core switch and core switch interface which connects to router ?

That depends on many things, first being whether your existing queue depths are optimal for your needs.

When you use policy maps, I believe they generally override the interface hold-queue settings. Often switches have specific commands for buffer management.
