Creating QoS Policies
This function creates a policy map that can be attached to multiple interfaces.
Create a policy map, specify the name of the policy map, and then use the class
parameters to configure policies for traffic that matches criteria defined in a class
map.
A policy map can contain multiple class statements that can be applied to the same
interface with the Service Policy Settings Page. Or you can create a separate policy
map for each type of traffic that may enter a port.
You can configure up to 8 policers on Fast Ethernet ingress ports, and up to 128
policers on Gigabit Ethernet ingress ports.
Policing is based on a token bucket, where bucket depth (i.e., the maximum burst
before the bucket overflows) is by specified the burst-byte field, and the average rate
tokens are removed from the bucket is by specified by the rate-bps option.
Use the Policy Map page to specify the name of the policy map, and use the Policy
Table to configure policies for traffic that match criteria defined in a class map.
A policy map can contain multiple class statements that can be applied to the same
interface with the Service Policy Settings page. Or you can create a separate policy
map for each type of traffic that may enter a port.
