Cannot get FastEthernet QoS working on 3550

mshickell

Level 1

I need to lock down the bandwidth awailable to one port of a 3550. I

understand the bandwidth command is present but non functional on the

3550 but have not been able to have the port get any slower during

testing.

I'm trying to use 8000 bits per second to test and then increase the

bandwidth once I've proved the configuration is working.

None of the outputs below register any packets hitting the policy.

Any help appreciated
