snmp-server enable traps mpls rfc ldp
To enable the sending of Multiprotocol Label Switching (MPLS) Label Distribution Protocol (LDP)
Simple Network Management Protocol (SNMP) notifications defined in RFC 3815, use the
s
nmp-server enable traps mpls rfc ldp command in global configuration mode. To disable the sending
of MPLS LDP notifications, use the no form of this command.
snmp-server enable traps mpls rfc ldp [pv-
limit | session-down | session-up | threshold]
no s
nmp-server enable traps mpls rfc ldp [pv-limit | session-down | session-up | threshold]
Syntax Description
Command Default The sending of SNMP notifications is disabled by default.
If you do not specify an optional keyword, all four types of MPLS RFC LDP notifications are enabled
on t
he label switch router (LSR).
Command Modes Global configuration (config)
Command History
Usage Guidelines Use this co
mmand to enable the LDP notifications supported in Definitions of Managed Objects for the
Multiprotocol Label Switching (MPLS), Label Distribution Protocol (LDP), RFC 3815.
The MPLS LDP pv
-limit (mplsLdpPathVectorLimitMismatch) notification provides a warning message
that can be sent to the network management station (NMS) when two routers engaged in LDP operations
have a dissimilar path vector limits. We recommend that all LDP-enabled routers in the network be
configured with the same path vector limits.
The value of the path vector limit can range from 0 to 255; a value of 0 indicates that loop detection is
o
ff; any value other than 0 up to 255 indicates that loop detection is on and, in addition, specifies the
maximum number of hops through which an LDP message can pass before a loop condition in the
network is sensed.
pv-limit (Optional) Enables or disables MPLS RFC LDP path-vector (PV) limit
m
ismatch notifications (mplsLdpPathVectorLimitMismatch).
session-down (Optional) Enables or disables MPLS RFC LDP session down notifications
(m
plsLdpSessionDown).
session-up (Optional) Enables or disables MPLS RFC LDP session up notifications
(m
plsLdpSessionUp).
threshold (Optional) Enables or disables MPLS RFC LDP threshold exceeded
n
otifications (mplsLdpInitSessionThresholdExceeded).
