Configuring Global Settings 3-17
Configuring SNMP
The SNMP manager queries the agents by means of OIDs. Each OID uniquely identifies
a single MIB variable. For example, the OID 307.3.2.1.1.1.2.0, returns the portname for
port S0, and the OID 307.3.2.1.1.1.2.1 returns the port name for port S1 (see Table 3-5).
