QoS - In class-map config cannot issue a match port tcp command

[keithsauer507]

Cisco 2901 router,

Issue:  VMWare vSphere replication has no means to throttle traffic until upgrading to 6.0 release which we are not ready to do yet.

Solution: Would like to throttle this traffic out our WAN through our 2901 router.  The existing traffic uses destination ports 39444 and 44046.

I thought that if I was in a class-map config, I could do something like

match port tcp eq 39444

But I get % Invalid input detected at '^' marker.

Any idea how to set this up?

You could match against an access-list that permits devices only with those port numbers to be match against

something like

class-map TEST

match access-group TEST

access-list TEST permit tcp .......... eq 39444

As Mark shows.

Thank you, that makes sense!
