Limit bandwidth on a switch-port?

serge_van_waes · ‎03-26-2007

We want to share an Internet-connection with a C2960 and limit the bandwith on each port (each customer on a port).

I try the parameter "max-reserved-bandwidth" on an interface but there was no difference in bandwith on this port.

Is there a way to limit the bandwith on a switch-port?

Or are there other opportunities?

Thanks!

You can limit the connection by police or shape the traffic based on customer requirments or you can use rate limt command.

For max-reserved-bandwidth is just how much you will remain for routing and other issue which is by default 75%.

I hope this is inforamtive for you and rate if it is.

Thanks for the information.

I will explain a bit more....

We haven an Internetconnection of 10 Mb, connected on a C2960 switch. We want to limit the bandwidth on each switch-port to 1 Mbps.

What is the best command we can use on the switch? Do you have some examples for me? (I am not a Cisco specialist)

Thanks!

if the 2960 is capable of Layer 3 switching (meaning routing) you could use a CAR policy. Commited Access Rate.

The Committed Access Rate (CAR) and Distributed CAR (DCAR) services limit the input or output transmission rate on an interface or subinterface based on a flexible set of criteria.

you can use the rate-limit command on the interface.

I think interface rate-limiting isn't supported on the 2960, specificaly IOS 12.2(25)SEE

See ref.

Although CISCO does provide contradictory info

Please ignore my hastily summarized posts.

Hello,

You can use policing and shaping on the switch ports to achieve the same. Please see the link below of configuring the same:
