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 either traps, informs, or both. Use the snmp-server host global configuration command to specify whether to send SNMP notifications as traps or informs.

Table 33-5describes the supported switch traps (notification types). You can enable any or all of these traps and configure a trap manager to receive them.

Table 33-5 Switch Notification Types

		Notification Type
		Keyword	Description
		bgp	Generates Border Gateway Protocol (BGP) state change traps. This option is
			only available when the IP services feature set is enabled.
		bridge	Generates STP bridge MIB traps.
