display bfd configuration

display bfd configuration

Function

The display bfd configuration command displays the BFD session configuration.

Format

display bfd configuration { all | static } [ for-ip ] [ verbose ]

display bfd configuration { static name session-name | discriminator local-discr-value | dynamic | peer-ip { peer-ip | default-ip } | static-auto } [ verbose ]

Parameters

Parameter

Description

Value

all

Displays the configuration of all BFD sessions.

-

static

Displays the configuration of static BFD sessions.

-

for-ip

Displays the configuration of BFD sessions for detecting an IP link.

-

peer-ip peer-ip

Specifies the peer IP address bound to the BFD session.

-

verbose

Displays detailed configuration of BFD sessions.

-

name session-name

Displays the configuration of a specified static BFD session. session-name specifies the name of the BFD session.

The value is a string of 1 to 15 characters without spaces.

dynamic

Displays dynamic BFD configurations and the configurations of static BFD sessions with automatically negotiated discriminators.

-

discriminator local-discr-value

Displays the configuration of BFD sessions with a specified local discriminator.

The value is an integer that ranges from 1 to 16383.

default-ip Display statistics about BFD sessions with the default multicast address. -

static-auto

Displays the configuration of static BFD sessions with automatically negotiated discriminators.

-

Views

All views

Default Level

1: Monitoring level

Usage Guidelines

Usage Scenario

When multiple BFD sessions exist, you can view information about certain BFD sessions by specifying the parameters such as the type, name, and peer IP address.

Precautions

If a static BFD session with automatically negotiated discriminators and a dynamic BFD session share the same configurations, you can view that the shared session configurations by BFD session type (static and dynamic).

Specification

CFG Name

BFD session name.

CFG Type

BFD session setup type:
  • S_IP_IF: indicates a single-hop BFD session that is established statically and bound to an interface.

  • S_IP_PEER: indicates a multi-hop BFD session that is established statically.

  • Dynamic: indicates a BFD session that is dynamically established.

  • Entire_Dynamic: indicates a BFD session that is entirely and dynamically established.

  • S_AUTO_IF: indicates a static single-hop BFD session with automatically negotiated discriminators.

  • S_AUTO_PEER: indicates a static multi-hop BFD session with automatically negotiated discriminators.

LocalDiscr

Local discriminator of the BFD session.

MIndex

Configuration entry index of a BFD session.

SessNum

Number of BFD sessions in a configuration entry.

Commit

Flag of enabling a BFD session.

After you run the commit command to commit configurations in the BFD session view, the flag is displayed as True. Otherwise, it is displayed as False.

AdminDown

Flag of the management status of a BFD session.

After you run the shutdown (BFD session view) command to disable the local session in the BFD session view, the flag is displayed as True. Otherwise, it is displayed as False.

Total Commit/Uncommit CFG Number

Total number of BFD sessions that are committed through the commit command in the BFD session view and total number of BFD sessions that are not committed.

  • If one-hop BFD for an IP link is used, this field is displayed as Interface and the name of the bound local interface.

  • Static_Auto: indicates the statically established BFD sessions with automatically negotiated discriminators.

Bind Session Type

Mode in which a BFD session is established:
  • Static: indicates the BFD sessions that are established through the static configurations.

  • Dynamic: indicates the BFD sessions that are triggered dynamically.

  • Static_Auto: indicates the statically established BFD sessions with automatically negotiated discriminators.
