I have 10 Mbps Internet Leased Line connected to serial interface of Cisco 1841 Router.I want to reserve bandwidth say 2 Mbps dedicated for my CEO.
I am i can use CBWRQ QoS tool to reserve the bandwidth. But i suppose that, this QoS tool plays role only during Congestion.
How to reserve Bandwidth permanently? Can any help me
My understanding is this is a minimum bandwidth guarantee so he will always get it.
If there is no congestion then he should get his 2Mbps of traffic anyway. Only if there is not enough bandwidth for his 2Mbps on the line will the QOS config become effective.
This is the way i understand it.
You could use the priority command and use a class-map to identify your CEO's traffic eg.
access-list 101 permit ip host any
match access-group 101
service-policy output CE0
Your CEO would be guaranteed 2Mbps at all times although he may get more if the line is not busy. Your CEO PC/laptop would need a static IP address.
