Environment

VMware Smart Assurance - SMARTS

Cause

MIB readonly community string does contains "@" characters. For Cisco devices, the @ symbol tells the SNMP agent that everything after the "@" symbol is a "context". This is typically used to query a specific VLAN for bridging information, and would look something like this for example:

public@vlan2222

The above would return information regarding VLAN 2222 using the community string "public".

Resolution

Check to ensure that the readonly community string does not contain any "@" characters. See the following article on the Cisco website for more information. Look in the section entitled, "snmp-server community":
