Bandwidth control in Catalyst 3550 switch 1

[imprise]

How can I control bandwidth of a particular port in the Catalyst 3550 switch?

Thanx in advanced

What do you mean? Setting it to a particular speed? Like 10, 100, or 1000?

If that's the case

config t
int <interfacd>
speed <10/100/1000>
duplex <half/full>

The end device has to be set to the same speed or you will encounter errors on the interface.

Thanks to your reply.
I mean Traffic Shaping that we use in routers to limit an interface bandwidth.

I'm not sure you can do this on an interface of a switch. I could be wrong.

The 3550 supports per-port ingress and egress policers. What is it you are trying to do?

Generally with a switch you normally classify/police on the ingress port. For example if you want to police a port to 10Mbps:

ip access-list standary Port-1-IP
permit any
!
class-map Port-1-Class
match access-group Port-1-IP
!
policy-map Police-Port-1
class Port-1-Class
police 10000000 8000 exceed-action drop
!
interface FastEthernet0/1
service-policy input Police-Port-1
!


Egress policies are also supported on the 3550 platform but since it is now EOS and the 3560/3750 platform has effectively taken it over these are not recommended since the 3560/3750 only supports ingress policies.
