SNMP Community name limitations

[m-loughry]

I am trying to find something that references the limitations (characters and length) for defining community strings for the various versions of snmp/ios.

There aren't any limitations, but there are some hints:

- suggest a minimum of 6 characters in length (for security purposes)

- do not use @ or * in community strings as they cause problems with certain network management applications

I have also found that $ is a problem in baseline templates if you try to deploy (LMS 2.5)
