Figure 5- 4. SNMP window
Under SNMP Management, enable or disable SNMP Agent or SNMP Traps by using the check
boxes. An SNMP Agent is software that runs locally on the device. A defined set of variables
(managed objects) is maintained by the SNMP agent and used to manage the device. Traps are
messages that alert network personnel of events that occur on the Switch. The events can be as serious
as a reboot (someone accidentally turned OFF the Switch), or less serious like a port status change.
The Router generates traps and sends them to the trap recipient (or network manager). Typical traps
include trap messages for Authentication Failure, Topology Change and Broadcast/Multicast Storms.
In the Name, Location and Contact fields, enter the appropriate information of the Network
Administrator. Under Community, enter the name of an SNMP community string that defines the
relationship between the SNMP manager and an agent. The community string acts like a password to
permit or deny access to an agent on the Router. The defining characteristic associated with the
community string is the Access Right. The agent's access right can be set as either read/write or read-
only. Under Traps enter the Destination IP address and Trap Community Name so that the agent
sends traps to the management server. The Trap Version can also be set to either SNMP V1 (to
specify that SNMP version 1 will be used) or SNMPv2c, which supports both centralized and
distributed network management strategies. SNMP V2c includes improvements in the Structure of
Management Information (SMI) and adds some security features.
