SNMP Community

I am creating a new SNMP community for my company.  This will be the first SNMP community we have ever used.  My question is:  What should I watch out for while creating this community and is there anything that could potentially cause a problem with existing configurations or interfaces from implementing SNMP?

Any help is appreciated.

Only thing I've seen is some devices don't like special characters in Community strings.  You may also want to look into SNMP v3 for more security.

I think this is SNMPv3.  So if I implement it wrong somehow, is it going to drive my network to a halt?  Just looking for caveats before I plow into it.

No, it just won't work.

Another thing you'll hear is not to use 'Public' as your string name since that is default for a lot of systems, use something unique.

You want to use something strong like:  cHaNg3m32dAy (I didn't use special characters because some gear I've come across don't like them).

Most basic advice:
"community" = "password"
Use the same conventions to select an SNMP community as you would a good password. Not easy to guess, not in the Dictionary, combination of Upper case, lower case and numbers, etc, etc..

Create 2 community passwords and keep them consistent throughout your network. One password for Read Only and one password for Read Write ..

Thanks, lrmoore.  I was waiting on you to chime in. haha  Thanks to everyone for helping out on this one.  Just being overly cautious as I really like this new job.  :)
I'll update this thread and award points when I finish it.  Should be done with this by Tuesday of next week.
