This object specifies whether standard mib-II defined linkUp/
linkDown, extended linkUp/linkDown (with extra varbinds in
addition to the varbinds defined in linkUp/linkDown) or
cieLinkUp/cieLinkDown notifications should be generated for
the interfaces in the system.
'standardLinkUp' - generate standard defined mib-II
linkUp notification if
'ifLinkUpDownTrapEnable' for the
interface is 'enabled'.
'standardLinkDown' - generate standard defined mib-II
linkDown notification if
'ifLinkUpDownTrapEnable' for the
interface is 'enabled'.
'additionalLinkUp' - generate linkUp notification with
additional varbinds if
'ifLinkUpDownTrapEnable' for the
interface is 'enabled'.
'additionalLinkDown' - generate linkDown notification with
additional varbinds if
'ifLinkUpDownTrapEnable' for the
interface is 'enabled'.
'ciscoLinkUp' - generate cieLinkUp notification
if the 'ifLinkUpDownTrapEnable' for the
interface is 'enabled'.
'ciscoLinkDown' - generate cieLinkDown notification
if the 'ifLinkUpDownTrapEnable' for the
interface is 'enabled'.
If multiple bits are set then multiple notifications will
be generated for an interface if the 'ifLinkUpDownTrapEnable'
for the interface is 'enabled'.
