  • Enabling SNMP on Cisco Switches and bandwith issues

    Hi kind people, I've been charged with enabing snmp on all our Cisco Switches to enable some external people to monitor our network and work out how and what is utilizing our bandwidth. I must admit that I have no idea where to start from, We use mostly 2950 switches and I'm pretty comfortable with the CLI, but I'm totally fazed by where to start from. I would imagine that if someone wanted to monitor something, then what they want to monitor should be 'sent out' for them to monitor, in which case I'll be saying to each switch, 'display this or that to this location or that location' so that someone will capture whatever you've been configured to send out.

    I've read about communities, traps, informs but I can't put everything together to make any sense. Can someone help me? I'll provide more info if I haven't made myself clear with this piece. thanks for your help.

    It might be useful to note that in all the offices, the switches are configured as clusters, i.e 1 command switch and a number of slave switches.

    I have never done this myself, but I did find this article that might guide you.
