Calculate traffic amount on interface

Team:

I have not deployed any monitoring software yet; however, Cacti is in the works. But is it possible to change ‘five minute input rate / five minute output rate’ time interval from 5 min to secs and get an accurate account of traffic going over a FastEthernet interface? Would I choke the hardware (3750) if I can change this attribute? Would this be a good method to see the load/traffic values in real time?

BACKGROUD:

The server team has deployed a new SQL server, and the DB devs are complaining that it is slow. I am suspecting that more traffic is going over the interfaces then what the ‘server team’ and ‘db devs’ indicated because they know I would raise a stink. I do not have access to the database server, nor the other end, yet I have access to network gear between the points.

Since I have never faced this type of issue, or problem – I need some direction and/or suggestions on how to troubleshoot this type of issue.

Thanks

JJ

Calculate traffic amount on interface

Hi Jason,

Issue the command load interval 30  on the interface and it will start displaying the input/output rate for 30 secs.

This won't impact the efficiency of the switch..

For further troubleshooting of the issue check for any output drops/ input errors/crc in the show interface fax/y output.

Thanks
