Controlling utilization on switch port [7:39038]
Greetings all, Is there a trick or a way to control utilization on a switch port? Assuming we want the user to use only 5 MB instead of 10. No special requirement at this time, just curious. Thanks..Nabil Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=39038t=39038 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: Controlling utilization on switch port [7:39038]
I imagine it may depend on the switch. On the 3500's (or I guess any switch with IOS), you can specify the bandwidth command on any interface, but I've never tried it and don't know how well it works.

Re: Controlling utilization on switch port [7:39038]
Similar use to the bandwidth command on routers - calculation of path costs. Can't have any effect on the clocking speed though. Looking at the URL you gave though there are loads of interface commands missing like description, loopback, logging to name but a few. Haven't checked any others but doesn't look like a very complete list. They're from 12.0.5 as well..dunno what's happened there...they got lazy?

RE: Controlling utilization on switch port [7:39038]
You could use a feature called storm control, I have not actually used this to control Unicast utilization ( mostly use this feature for Broadcast control) however the principle would be the same for multicast and Unicast traffic. Storm control is enabled, the switch monitors packets passing from an interface to the switching bus and determines if the packet is unicast, multicast, or broadcast. The switch monitors the number of broadcast, multicast, or unicast packets received within the 1-second time interval, and when a threshold for one type of traffic is reached, that type of traffic is dropped. This threshold is specified as a percentage of total available bandwidth that can be used by broadcast (multicast or unicast) traffic. Look at the below URL for configuration http://www.cisco.com/univercd/cc/td/doc/product/lan/c3550/1218ea1/3550scg/sw bcsup.htm#xtocid7 Doug -Original Message- From: Gaz [mailto:[EMAIL PROTECTED]] Sent: Thursday, March 21, 2002 1:23 PM To: [EMAIL PROTECTED] Subject: Re: Controlling utilization on switch port [7:39038] Similar use to the bandwidth command on routers - calculation of path costs.

Even on routers bandwidth is simply used to calculate load (x/255) and used in routing protocol metrics (IGRP/EIGRP for sure), but doesn't affect the actual bandwidth/speed of an interface.

I don't know if it's lazy or they just got tired of managing so many different versions of the same thing. Personally I reference their mammoth IP IOS command guide. It's in three volumes. Here are links to them: (careful of wrap on all of these URLs) Volume I - Addressing and Services http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fipras_r/ Volume II - Routing Protocols http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fiprrp_r/ Volume III - Multicast http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fiprmc_r/ That's a combined document of almost 1200 pages.

Re: Controlling utilization on switch port [7:39038]
The bandwidth command in IOS is used by some routing protocols (part of metric calc) and other router functions/services. This command on the switch, being IOS is probably the same and I'm not sure how effective it would be unless the switch had L3 functions, etc. --- sam sneed wrote: I never knew about this command.
