Unsupported characters for SNMPv3 community strings in Spectrum

Products

• CA Spectrum

Issue/Introduction

When Discovering devices via SNMPv3 in Spectrum, it is important to note that Spectrum supports only Alpha-numeric characters in SNMPv3 usernames and passwords. Using unsupported characters in SNMPv3 usernames and passwords could prevent Spectrum from authenticating with the device.

Environment

Release: Any
Component: SPCDIS

Resolution

Spectrum does not support Special Characters is username or password for SNMP.

SNMPv3 unsupported characters for user names are: period (.), comma (,), pound (#), brackets ({ }), single quotes (‘ ’), and double quotes (“ ”). 

 

For passwords:

Supported : (.) (,) (#) ({}) (!) (@) ($) (^) (&) (*) (()) (-) ( _ ) ( [)]) (\) (|) (?) (/) (<>) (:)

Un-supported : (;)  (') (")  (%)

 

If you edit the username and passwords with the above special characters in the v3 community string attribute (Community_Name - 0x10024)  then these characters need to be prefixed with an escape backslash characters (\). This is because when the v3 community string field is edited directly Spectrum expects that it contains V3 Context name (as this is the only way v3 context names are supplied) and would result in incorrect V3 username and passwords.
