Priority Queuing in Gig

[Sam Pragash]

Can I configure Priority Queuing in Gigabit Interfaces of a router? or it will work only Serial interfaces?

First of all, "priority queueing" is an obsolete method of pseudo-QoS that should not be used anymore.

Then, describe you problem in full, e.g. you have a gigabit connection but the actual bandwith is 10 mpbs.

In that case you will need to configure shaping before queuing, there are many threads, you can search here or on cisco.com

I have a Wan Link of 2Mbps(with Ethernet output) connected in Gi0/2 of Cisco 2911.

Requirement:

I want to prioritize the traffic of two source ip's for eg: 192.168.10.1 & 10.2, like if it needs it should take the full 2 Mbps. If it doesn't need then others can utilize the available bw.

Answered above, you have to do MQC with LLC. Can use search function for many examples.

For QoS to prioritize, it needs to "see" congestion.

As Paolo has mentioned, first you'll want to shape.  Then you can prioritize under the shaper.

To meet your requirements, something like:

ip access-list extended sample

permit ip host 192.168.10.1 any

permit ip host 192.168.10.2 any

class-map match-any sample

match access-group sample

policy-map sampleParent

class class-default

shape average 2000000

service-policy sampleChild

policy-map sampleChild

class sample

bandwidth percent 99

int g0/2

service-policy output sampleParent
