I must change the QoS configuration on a router Cisco 871 (IOS: IP services 12.4(24) T1). The service policy is applied to the routed port, fastethernet4.
Can I do the changes from within the policy-map configuration without removing the service policy? Will the effects take place as soon as I press enter?
If I'll have to remove the service policy before doing any change, will this trigger the port to go down because the policy map is actually policing? I was thinking in that case to put an access list inbound on the WAN port to stop all traffic..
You can change the policy-map and attached class-maps while it's attached to the interface.
All changes take affect upon pressing enter!
If you delete an ACL or remove the match statement from the Class-map traffic will stop matching and look to the next class-map.
You need to be very careful when doing this and make sure you understand what will happen when you make the change. For example
Your matching a /32 address and not policing, but then matching a /24 that includes the /32, but policing the subnet to a CIR. This allows the single /32 to use all bandwidth but the other devices are policed down.
If you remove the ACL for the /32 or remove the class for the /32 it will then match with the /24. That could cause a loss of traffic on the IP address.
