Disabling Up/ Down Notifications on an Interface

You can disable linkUp and linkDown notifications on an individual interface. You can use this limit
notifications on flapping interface (an interface that transitions between up and down repeatedly).
To disable linkUp/linkDown notifications for the interface in interface configuration mode, perform this
task:
Command
switch(config-if)# no snmp trap link-status

IEFT Cisco—Cisco NX-OS sends the notifications (linkUp, linkDown) defined in IF-MIB and
notifications (cieLinkUp, cieLinkDown) defined in CISCO-IF-EXTENSION-MIB.my , if
ifLinkUpDownTrapEnable (defined in IF-MIB) is enabled for that interface. Cisco NX-OS sends
only the varbinds defined in the linkUp and linkDown notifications.
IEFT extended Cisco—Cisco NX-OS sends the notifications (linkUp, linkDown) defined in IF-MIB
and notifications (cieLinkUp, cieLinkDown) defined in CISCO-IF-EXTENSION-MIB.my, if
ifLinkUpDownTrapEnable (defined in IF-MIB) is enabled for that interface. Cisco NX-OS adds
additional varbinds specific to Cisco Systems in addition to the varbinds defined in the IF-MIB for
the linkUp and linkDown notifications.
