Syntax interface [ip-int-name] [detail] [family]
interface resource-failures [family]
Context show>router>ldp
Description This command displays configuration information about LDP interfaces.
Parameters ip-int-name — The name of an existing interface. If the string contains special characters (#, $,
spaces, etc.), the entire string must be enclosed within double quotes.
detail — Displays detailed information.
family — Displays either IPv4 or IPv6 active LDP information.
resource-failures — Displays which interfaces are in overload.
Output LDP Interface Output — The following table describes the LDP interface output fields.
Label Description
Interface
Specifies the interface associated with the LDP instance.
Adm
Up — The LDP is administratively enabled.
Down — The LDP is administratively disabled.
Opr
Up — The LDP is operationally enabled.
Down — The LDP is operationally disabled.
Hello Factor
The value by which the hello timeout should be divided to give the
hello time, for example, the time interval, in seconds, between LDP
hello messages. LDP uses hello messages to discover neighbors and to
detect loss of connectivity with its neighbors.
Hold Time
The hello time, also known as hold time. It is the time interval, in sec-
onds, that LDP waits before declaring a neighbor to be down. Hello
timeout is local to the system and is sent in the hello messages to a
neighbor.
KA Factor
The value by which the keepalive timeout should be divided to give the
keepalive time, for example, the time interval, in seconds,
between LDP keepalive messages. LDP keepalive messages are sent to
keep the LDP session from timing out when no other LDP traffic is
being sent between the neighbors.
KA Timeout
The time interval, in seconds, that LDP waits before tearing down a
session. If no LDP messages are exchanged during this time interval,
the LDP session is torn down. Generally the value is configured to be 3
times the keepalive time (the time interval between successive LDP
keepalive messages).
