Chapter 27 Configuring SNMP
Configuring SNMP
Some notification types cannot be controlled with the snmp-server enable global configuration
command, for example, tty and udp-port. These notification types are always enabled. You can use the
snmp-server host global configuration command to a specific host to receive the notification types
listed in Table 27-4.
Beginning in privileged EXEC mode, follow these steps to configure the switch to send traps or informs
to a host:
config Generates a trap for SNMP configuration changes.
copy-config Generates a trap for SNMP copy configuration changes.
entity Generates a trap for SNMP entity changes.
envmon Generates environmental monitor traps. You can enable any or all of these
environmental traps: fan, shutdown, supply, temperature.
flash Generates SNMP FLASH notifications.
hsrp Generates a trap for Hot Standby Router Protocol (HSRP) changes.
mac-notification Generates a trap for MAC address notifications.
rtr Generates a trap for the SNMP Response Time Reporter (RTR).
snmp Generates a trap for SNMP-type notifications.
stpx Generates SNMP STP Extended MIB traps.
syslog Generates SNMP syslog traps.
tty Sends Cisco enterprise-specific notifications when a Transmission Control
Protocol (TCP) connection closes.
udp-port Sends notification of the User Datagram Protocol (UDP) port number of the
host.
vlan-membership Generates a trap for SNMP VLAN membership changes.
vlancreate Generates SNMP VLAN-created traps.
vlandelete Generates SNMP VLAN-deleted traps.
vtp Generates a trap for VLAN Trunking Protocol (VTP) changes.

port] {v1 | v2c | v3 [auth {md5 | sha}
auth-password]} [encrypted] [access
access-list]
Configure an SNMP user to be associated with the remote host created in
