Want to know whether "max-reserved-bandwidth" command is supported on fastethernet/gigethernet interfaces. I am working with 7600 router (IOS, 12.2(33)SRA2) with 16 Fastethernet Interfaces and try to use "max-reserved-bandwidth" command on the Fastethernet interfaces. It is not supporting. If it is not a supported option, may I have some document on the same?

Hi Sebastian,
Yes in my experience also the command is not supported on the 7600 ethernet ports.
Since this is a Fancy-Queuing feature, and the 7600 ethernet ports use Hardware Queues and dont support Fancy-Queuing.
For the document, here is a link which has QPM/Platform/IOS compatibility list.
Although this is meant for QPM, it gives a good insight on what QOS feature is supported on what platform with what IOS.

Hi Swaroop,
Thank you.
But, may I get some document which can tell that this particular command is not supported with this combination (7600 with 7600-SIP-200 module)? Or something like "this command belongs to particular group of QoS mechanism and so it is not supported on this module?
Regards

Hi Sebastian,
I dont have such a document.
But to help you decide, if you really need this command, you can consider this.(If you have not already given this a try, if you have you can ignore it)
1) This command is in place to allocate more than the default 75% which can be used for Fancy Queuing (with Policy Map).
2) For eg: If you cannot configure you SIP-200/400/600 for your SPA interfaces, for more than 75% of the port speed, then you need this.
3) You can try out using a policy map which will allocate 1000 Meg of traffic into different classes and apply it on a 1 gig interface, if it allows you, then you definately dont need this command. As you are able to allocate all the 100% bandwidth, you may decide to skip this command.
