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-if)#service-policy input 311mbps

if you enable MLS with
the only risk is that by default all ports are untrusted and the risk is that all traffic is remarked to DSCP 0
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
