An
SNMP agent is a software component that responds to queries about the management data of the switch, and reports events to another device acting as an SNMP manager.
The management data for a switch can include:
-
operational state information (interface status, mode of operation, etc.)
-
configuration parameters (IP address, features enabled / disabled, timer values, etc.)
-
performance statistics (frame counters, event logs, etc.)
If a switch is equipped with SNMP agent software, a designated SNMP manager can:
-
retrieve management data about the switch
-
control the switch by editing its configuration settings
-
receive traps—or notices of events—affecting the state of the switch
