I have Cisco 2811/1841 Routers and Cisco 2906 switches (24/48port). I am looking to enable SNMP on them. Either SNMPv2 or SNMPv3. I need to find documentation on this and any step by step advice would be a real help.

The article http://itknowledgeexchange.techtarget.com/network-technologies/how-to-secure-snmp-in-cisco-switches-and-routers/ contains good samples and takes care of security too.

If you need to avoid any access-list/security issue just remove the access-list number on the end of snmp commands.

2. if you want to have RW access, the above applies, but it is highly recommended that you use another community name other than public (long and random is good)
ip access-list 1 permit ip host 1.1.1.1 !  ip of server running mrtg
snmp-server community somethingrandom RW 1

OK "ludo friend",

I am interested in setting up v2c for now and I will work on v3 later.

So on every switch and router I want to monitor are these the commands I need to enter in privledged mode?

snmp-server community somethingrandom1 RO 1
snmp-server community somethingrandom2 RW 1
snmp-server enable traps
snmp-server host "ip of NMS server"
if you're just monitoring... use the below - the rest are for traps or snmp write access

access-list 1 permit host 1.1.1.1
snmp-server community somethingrandom1 RO 1
