Enabling SNMP

Zones: SNNP, Network Analysis Software
Tags: Cisco, Cisco, SNMP, 6509 Catalyst
Sorry for the armature question here but Im looking to enable SNMP on my network.
Would it be best to enable SNMP on the core switch or will this create too much over head or is the Network Management Station normally a regular server?
I see this article from cisco but it does not go into detail on how exactly to quickly gain an understanding and correctly deploy.

Any device you want to monitor with SNMP you will need to enable snmp (snmp-server community community name RO/RW). usually just enabling snmp adds very little overhead. Your device will use a little more processor and memory but nothing major. If you enable traps though you will increase the overhead on both the network and router resources. The addtitional overhead from traps just depends on which traps you enable.

My suggestion is to test this on a non production device (if possible) and see what the results are. I have all my network gear set up with snmp w/ traps and i don't even notice the difference.

Can you tell me what steps to follow in order to set this up?
Also would i just enable it on the core switch or would i have to enable it on all the switches?

You will enable it on all switches. If you just want to enable snmp and collect snmp information for your switches from a monitoring server then enter these comands in global config mode

Router(config)# snmp-server community community_name ro

community_name is the name of your snmp community. Also the ro at the end means Read Only. You can also set this to rw or Read Write but that will allow snmp devices to make changes to your switch. I recommend only using ro unless you have a specific reason to use rw.

Here is a link to snmp basics for cisco devices. good read
