In Cisco 4500 series switch is it possible to limit bandwidth for Gibagit ethernet port? For example port gi 1/0 should have only 5 Mbps upload and download speed

Thanks and Regards

hi jon,

Thanks for the URL. I am not familiar with QoS . Can you provide me a config for ingress and egress policing on Gigabit interface 0/1 . the IP connected with the port is 192.168.1.10. The user will have all kind of access ( Http, SMTP, HTTPS, POP3 etc)

Any simple config for me to apply them on the switch?

Regards

Prabu

The 3 values are as below in cisco.

bps : - Average rate in bits per second. The value must be in increments of

8 kbps.

burst-normal: -Normal burst size in bytes. The minimum value is bps divided by 2000.

burst-max:- Excess burst size in bytes.

The most important thing in this one is to remmber that the normal and max burst are calulated in BYTES.

so the statement means 5 meg,Noraml is 5 Meg, Above 5 Meg drop.

hope this helps let us know i may be wrong but it does work fine for me.
