Enabling Link-Change Traps

By default, a switch is enabled to send a trap when the link state on a port changes from up to

down (linkDown) or down to up (linkUp.) To reconfigure the switch to send link-change traps to

configured trap receivers, enter the snmp-server enable traps link-change command.

Syntax

[no] snmp-server enable traps link-change<port-list> [ all ]

Enables or disables the switch to send a link-change trap to configured trap receivers when the

link state on a port goes from up to down or down to up.

Enter all to enable or disable link-change traps on all ports on the switch.

Enabling SNMP traps on running configuration changes

Syntax

[no] snmp-server enable trapsfig-change [ transmission-interval

0-4294967295 ]

running-con

Enables SNMP traps being sent when changes to the running configuration file are made.

(Default: Disabled)

transmission-interval 0-2147483647 controls the egress rate for generating SNMP traps

for the running configuration file. The value configured specifies the time interval in seconds that

is allowed between the transmission of two consecutive traps.

None of the running configuration change events that occur within the specified interval generate

SNMP traps, although they are logged in the Configuration Changes History Table.

A value of 0 (zero) means there is no limit; traps can be sent for every running configuration change

event.

(Default: Zero)
