I'm trying to apply rate limiting onto a gigE interface. When I apply the service-policy command, I get the following message below.
What does the message mean and if I enable it on a production router will it suddenly drop packets affect user traffic?
Thanks in advance.
rtr(config)#inter g8/4
rtr(config-if)#service-policy input 311mbps
Warning (QoS): MLS QoS is disabled, marking/policing will be done after

Hello David,
the warning simply means that your configuration will not be effective (no marking / policing will be done) until you enable MLS at global level.
Caution:
if you enable MLS with
mls qos
the only risk is that by default all ports are untrusted and the risk is that all traffic is remarked to DSCP 0
see
multilayer switches use the concept of trusted / untrusted ports
so you need to decide what ports you want to trust and to configure them accordingly
Hope to help
Giuseppe
