Cat 5500 switch

[dong-lee]

Hi,

Is there any CatOS command that I can use to read input and output traffic?? I have Cat 5500 switch with CatOS version 5.5(11), but I couldn't find a single command that read input and outport traffic on a single port.

Also, does any one know SNMP mib number to pull port traffic information if there is any way to do it?

Thank you

Dong

Have you looked at the 'show port' commands. The 'show port mac module/port' may help. If you are looking for something similar to 'show interface' from an IOS router, you are out of luck.

Hi,

Thanks for your replay. Yeah, I'm aware of those commands but they aren't really what I'm looking for. I'm trying to get IN/OUT bandwidth per port something like "show interface". I guess I'm pretty much out of luck getting it.

Do you know if Cisco implement these command on lastest CatOS??

Thank you

Sorry, I have not used any of CatOS version 6 (old 5.5) so don't know. Sounds like snmp might be worth trying. CiscoWorks can graph link utilisation but not sure what mib it uses.

you can use the "show top report" - although this is not excatly what you're looking for, it could be useful.

Hi,

This command is useful, although, I don't think I can pull the out the information with snmp MIB. :) Thank you.

Oh, It didn't get the information on all of the ports when I ran the "show top background" command. Is this command limited to certain number of ports that it can scan?? It only scanned about 20 ports out of a little over 70.

Thanks again

Thanks for your comment, Pual... :)

But these commands are just a counter. I was looking for a snap-shot of port traffic(like "show inter Sx/x" give you 30second input/out rate).

Thanks again
