What do i have to do to change from SNMPv1 to SNMPv3 ?

[admin_2]

I was asked to evaluate how much effort is needed to change over from SNMPv1 to SNMPv3. What configuration is neccessary on the routers and what on the NMS ( CiscoWorks 2000, Netview ) ?

A software release 12.0(3)T is needed to support SNMP V3.

The section '. Which Versions of SNMP Are Supported in my Cisco IOS® Software Image?' at: http://www.cisco.com/warp/public/477/SNMP/snmp_faq.html#Q6 which wil tell you what IOS you need for SNMPv3

Neither CW2000 nor NetView supports SNMPv3. You'll need something else on the NMS side.
