Actually, I love the 3550s. I'm wondering why the 3550-12G doesn't support CAR. We want to use this for some metro access, but I can't rate limit the port. What gives? What are other people using in this capacity of low cost, GBIC dense boxes?
The 3550s don't use CatOS. They use IOS and are an L3 switch. However, I did do some research and came up with a QoS config that polices the traffic and drops any out of profile in conjunction with the time-based ACLs. It could have been a lot simpler with CAR support.
The 3550 does support policing using command "policer" in policy-map config, and also "mls qos aggregate-policer" in global config. You can specify certain rate and limit traffic to that rate, and drop traffic exceeding that rate. See example below:
class-map match-all data
match ip dscp 18
police 128000 80000 exceed-action drop
service-policy output policer
Do this help?? I believe this should solve your purpose.
You are correct and that is a good egress policy. I ended up with an ingress policy because I needed to match an ACL that was referencing time ranges. I haven't decided yet if there is going to be a need to also throw on an egress policy. Thanks for your reply. However, I'm sorry to see that I can't apply these policies to VLAN interfaces.
