Configuring SNMP Notifications
A trap manager is a management station that receives and processes traps. Traps are system alerts that
the switch generates when certain events occur. By default, no trap manager is defined, and no traps are
sent. Switches running this Cisco IOS release can have an unlimited number of trap managers.
Note
Many commands use the word traps in the command syntax. Unless there is an option in the command
to select either traps or informs, the keyword traps refers to traps, informs, or both. Use the snmp-server
host global configuration command to specify whether to send SNMP notifications as traps or informs.
Table 30-5
traps and configure a trap manager to receive them. To enable the sending of SNMP inform notifications,
use the snmp-server enable traps global configuration command combined with the snmp-server host
host-addr informs global configuration command.
