[kuldeep.kaur]

Hi Guys,

I would like to ask a question about priority in cbwfq queue. Suppose if i allocate 5mb to priority queue, and there is no traffic on priority queue, can other classess / traffic can use this queue if it is empty.

Tks

Yes, the priority queue (or LLQ) just sets a maximum bandwidth.  Note it will also drop traffic exceeding that bandwidth for the class assigned to that queue.  More info here: http://www.cisco.com/en/US/docs/ios/qos/configuration/guide/congstion_mgmt_oview_ps6441_TSD_Products_Configuration_Guide_Chapter.html#wp1001291
