4.4 SNMP Configuration.
In a large network, a network management system (NMS) based on the Simple Network
Management Protocol (SNMP) is often used to keep track of operations. SNMP,
created in 1988, is the standard protocol for managing network devices. Over TCP/IP,
SNMP usually uses UDP ports 161 (SNMP) and 162 (SNMP-traps).
An SNMP implementation involves three areas of functionality : the managed devices,
the SNMP agents, and the NMS. SNMP agents reside in network devices where they
use MIBs (information specific to the device) to interface the devices with the NMS —
which then monitors and controls devices via these agents.
SNMP achieves device management via a very small command set described in 5.1.6.
The switch can be managed via SNMP. From the SNMP Configuration menu (Figure
41), three submenus can be accessed :
Configure System Information (explained in Section 4.2.2.1)
Configure SNMP Community (explained in Section 4.2.2.2)
Configure Trap Receivers (explained in Section 4.2.2.3)
For more information on SNMP support within the switch, see the Appendix.
