Trap: warmStart

SNMP Trap

Description

Possible Cause

warmStart

The unit has reinitialized
itself.

The trap is sent after the
unit resets and stabilizes.

There are no
variable-bindings.

Reset command.

Power disruption.

Traps: linkUp and linkDown

The link SNMP traps are:

linkUp – The unit recognizes that one of the failed communication interfaces
is operational (up).

linkDown – The unit recognizes a failure in one of the communication
interfaces.

The following table describes the conditions that define linkUp and linkDown for
each interface:

Interface

linkUp/Down
Variable-Bindings

Possible Cause

Physical Sublayer – Represented by the entry in the MIB II Interfaces Table.

DDS network

(Supported by the
media-specific DDS
Enterprise MIB.)

ifIndex (RFC 1573)

ifAdminStatus
(RFC 1573)

ifOperStatus (RFC 1573)

fType (RFC 1573)

ddsStatus (DDS
Enterprise MIB)

linkDown – One or more
alarm conditions are active on
the interface.

Alarm conditions include:

– No Signal

– Out of Service

– Out of Frame

– Crossed Pair Detected

– In-band Framing Error

– Excessive Bipolar Violations

(BPVs)

linkUp – No alarms on the
interface.

Synchronous User
Data Port

(Supported by the
media-specific
RS232-Like MIB.)

ifIndex (RFC 1573)

ifAdminStatus
(RFC 1573)

ifOperStatus (RFC 1573)

fType (RFC 1573)

linkDown – The Alarm
condition active on the
interface is DTR Off . The DTR
alarm condition only generates
a linkUp/linkDown trap if the
DTE supports the DTR lead.

linkUp – No alarm on the
interface.
