I'm trying to mark ip precedence bits on a Cat 3550-48-emi. I've an int configured as a L3 int, and want to mark packets outgoing from that interface. I've tried with the CMS wizard but the packets have normal priority, not critical as I "configure". I've look for a tip but can't find anyone. Please help.
The FastEthernet 0/1 is the layer 3 int. I configure an access-list matching the traffic i want to mark (access-list 100), a class-map with the access-group, and a policy-map with the action to aply.
I tried to aply the policy to the output of fa0/1, but it doesn't appear on the running config after i put it, and it admit the command "3550_48_EMI(config-if)#service-policy output mark_critical" on that L3 int.
