Examples
This example shows how to create a policy map called
policy1
. When attached to an ingress port, the
policy matches all the inbound traffic defined in
class1
, sets the IP DSCP to 10, and polices the traffic
at an average rate of 1 Mbps and bursts of 20 KB. Traffic exceeding the profile is marked down to a
Traffic exceeding the profile is marked down to a DSCP value obtained from the policed-DSCP map and
then sent.

This example configures two class policies included in the egress policy map called
policy1
. Class1
specifies a policy for 802.1Q tunneling traffic that matches packets based on the outer VLAN ID (VLAN
2) and the inner VLAN IDs (3 to 8).

For class1, a minimum of 2000 kbps of bandwidth is expected to be delivered to this class in the event
of congestion. The queue reserved for this class can contain 40 packets before tail drop occurs.
This example shows how to shape the default class. This configuration associates a class-level policy
map with a VLAN-level policy map and then associates the VLAN-level policy map with a
physical-level policy map.
