SNMP

We currently have snmp v1 on some Switches. How do I get them up to Version 2 or 3? Thanks

We have C6509 running 12.2(18)SXF4

and Cat 4003/6 running Cat OS 6.4(10)

Also on the above switches have the line

snmp-server host x.x.x.x public.

If and when I do change the snmp public and private, do I also need to change this line to the modified value?

Practically no NMS software seems to bother checking the incoming SNMP trap's community string, so you'll find it makes no difference changing it or not.

Re: SNMP

If you want to enable v2c in this case you would configured something like:

snmp-server host 1.1.1.1 traps version 2c public

For SNMP V3, have a look at this link:

Re: SNMP

Thanks

What effect will my changing the

snmp-server community secret RW. The secret part to something else. As in all the Cisco examples, it was left as is.

SHould I change it or not. and what effect will changing it have and what is it used for?

THanks

Re: SNMP

Yes, you should change it to something more secure. public and private are simply used as examples. You shouldn't have public and private as your community strings.
