Display BFD Configuration for an IPv4 Interface

About this task

Use the following procedure to display BFD configuration on an interface.

Procedure

  1. To enter User EXEC mode, log on to the switch.
  2. Display BFD on a Gigabit Ethernet interface:

    show ip bfd interfaces Gigabitethernet [{slot/port[/sub-port][-slot/port[/sub-port]][,...][slot/all][all]}] [vrf WORD<1-16>] [vrfids WORD<0-512>]

  3. Display BFD on a VLAN interface:

    show ip bfd interfaces vlan [<1-4059>] [vrf WORD<1-16>] [vrfids WORD<0-512>]

Examples

The following example displays VLAN interface configuration information for BFD.

Switch:1>show ip bfd interfaces vlan 11
==========================================================================================
                                    Vlan Bfd
==========================================================================================
VLAN       STATUS     MIN_RX     INTERVAL   MULTIPLIER      VRF-ID
------------------------------------------------------------------------------------------
11         enable     200        200        3               0
The following example displays Loopback interface configuration information for BFD:
Switch:1>show ip bfd interfaces loopback
================================================================================
                          Circuitless IP Interface Bfd
================================================================================
INTF ID    STATUS     MIN_RX     INTERVAL   MULTIPLIER      VRF-ID
--------------------------------------------------------------------------------
1          enable     200        200        3               0
2          enable     200        200        3               2

Variable Definitions

The following table defines parameters for the show ip bfd interfaces command.

Variable

Value

{slot/port[/sub-port][-slot/port[/sub-port]][,...][slot/all][all]}
Identifies the slot and port in one of the following formats:

  • a single slot and port (slot/port)

  • a range of slots and ports (slot/port-slot/port)

  • a series of slots and ports (slot/port,slot/port,slot/port)

  • all ports on the same slot (slot/all)

  • all ports on the switch (all)

If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.

<1-4059>

Specifies the VLAN ID in the range of 1 to 4059. By default, VLAN IDs 1 to 4059 are configurable and the system reserves VLAN IDs 4060 to 4094 for internal use. On switches that support the vrf-scaling and spbm-config-mode boot configuration flags, if you enable these flags, the system also reserves VLAN IDs 3500 to 3998. VLAN ID 1 is the default VLAN and you cannot create or delete VLAN ID 1.

vrf WORD<1-16>

Specifies a VRF instance by VRF name.

vrfids WORD<0-512>

Specifies a VRF or range of VRFs by ID.
