In this section:
SNMP community strings are text strings that act as a rudimentary authentication mechanism for SNMP v1/v2. An SNMP manager places a community string (in plaintext) into an SNMP request when sending the request to a managed device such as an SBC 5200. The SNMP agent in a managed device ignores SNMP requests that do not contain a community string matching with the previously configured one. The SBC supports configuring up to eight SNMP community strings using the communityString
object described below.
For additional details about configuring SNMP, refer to Configuring SBC for SNMP.
