CISCO-UDLDP-MIB
AI MIB Summary
The CISCO-UDLDP-MIB monitors Cisco UniDirectional Link Detection Protocol (UDLD) states and error counters on Layer 2 interfaces to detect unidirectional link failures. It tracks specific metrics including UDLD neighbor discovery status, aggressive mode activation, and the count of detected unidirectional links per interface.

enable(true)/disable(false) Uni Direction

cudldpHelloIntervalIndicates interval in seconds at which each port
sends a hello packet to all of its neighbors at
steady state when the link has been identified as
bidirectional.rw INTEGER .1.3.6.1.4.1.9.9.118.1.1.2 |

cudldpInterfaceTableThe (conceptual) table containing the status
of UDLDP on the device's interfaces. SEQUENCE OF CudldpInterfaceEntry .1.3.6.1.4.1.9.9.118.1.2.1 |
cudldpInterfaceEntryA conceptual row of cudldpInterfaceTable. An
entry exists for each interface that supports
UDLDP. CudldpInterfaceEntry .1.3.6.1.4.1.9.9.118.1.2.1.1 |
cudldpInterfaceEnableThis variable is used to enable UDLDP on this
interface. If cudldpGlobalEnable is set to
'false' then this variable has no effectrw TruthValue -- Rsyntax INTEGER { -- true(1), -- false(2) -- } .1.3.6.1.4.1.9.9.118.1.2.1.1.1 |
cudldpInterfaceOperStatusThis mib oject contains the following values,
which has the meaning as:
'shutdown' - An Uni-Direction link has been
detected and the port has been
disabled.
'indeterminant' - Uni-Direction Link Detection
protocol has not collected enough
information to determine if the
link is bidirectional or not.
'bi-directional' - A bidirectional link has been
detected.
'not-applicable' - Uni-Direction Link Detection
Protocol is disabled.ro Enumeration .1.3.6.1.4.1.9.9.118.1.2.1.1.2 |
cudldpInterfaceAggressiveModeAn indication of whether the UDLDP aggressive mode
is enabled on this interface. If the
aggressive mode is set to 'true', an active port may
be shutdown in case of the abrupt loss of its
neighbor(s) because the loss of communication
(heartbeat) with the neighbor(s) is assumed to be
caused by a fault; thus, the cudldpInterfaceOperStatus
of the active port will be 'shutdown'. Instead, when
the aggressive mode is set to 'false', and if there
is a loss of communication with the neighbor(s), then
the cudldpInterfaceOperStatus of the active port
will be 'indeterminant'.
Therefore, this mode is recommended
only for links that don't use hubs, media converters
or similar devices, and where the unexpected loss of
the port's neighbor is not an admissible condition.rw TruthValue -- Rsyntax INTEGER { -- true(1), -- false(2) -- } .1.3.6.1.4.1.9.9.118.1.2.1.1.3 |
