| Quality of Service Commands

set cos

When a packet of size B bytes arrives at time t, the following happens:
If Tc(t)-B ≥ 0, the packet is green and Tc is decremented by B down to the
■
minimum value of 0,
else the packet is red and Tc is not decremented.
■
Example
This example creates a policy called "rd-policy, " uses the
the previously defined "rd-class, " uses the
that incoming packets will receive, and then uses the police rate command to limit
the average bandwidth to 100,000 Kbps.
Console(config)#policy-map rd-policy
Console(config-pmap)#class rd-class
Console(config-pmap-c)#set cos 3
Console(config-pmap-c)#police rate 100000
Console(config-pmap-c)#
This command modifies the class of service (CoS) value for a matching packet (as
specified by the match command) in the packet's VLAN tag. Use the no form to

Example
This example creates a policy called "rd-policy, " uses the
the previously defined "rd-class, " uses the set cos command to classify the service
that incoming packets will receive.
Console(config)#policy-map rd-policy
Console(config-pmap)#class rd-class
Console(config-pmap-c)#set cos 3
Console(config-pmap-c)#police flow 10000 4000 conform-action transmit
