show ip bfd interfaces

Display Bidirectional Forwarding Detection (BFD) configuration for a port, VLAN, or loopback on an IPv4 interface.

Syntax

show ip bfd interfaces gigabitethernet {slot/port[/sub-port][-slot/port[/sub-port]][,...][slot/all][all]}
show ip bfd interfaces gigabitethernet vrf WORD<1-16>
show ip bfd interfaces gigabitethernet vrfids WORD<0-512>
show ip bfd interface loopback <1-256>
show ip bfd interfaces vlan <1-4059>
show ip bfd interfaces vlan vrf WORD<1-16>
show ip bfd interfaces vlan vrfids WORD<0-512>

Command Parameters

{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.

vlan <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.

<1-256>

Specifies the loopback interface ID value.

Command Mode

User EXEC

Command Output

The show ip bfd interfaces command displays the following information:


Output field	Description
VLAN	Specifies the VLAN ID. This field displays only in output for VLAN interfaces.
PORT	Specifies the port number. This field displays only in output for GigabitEthernet interfaces.
INTF ID	Specifies the loopback interface ID. This field displays only in output for Loopback interfaces.
STATUS	Specifies whether BFD is enabled on the interface.
MIN_RX	Specifies the receive interval in milliseconds.
INTERVAL	Specifies the transmit interval in milliseconds.
MULTIPLIER	Specifies the multiplier used to calculate the amount of time BFD waits before declaring a receive timeout.
VRF-ID	Specifies a VRF ID.

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
================================================================================
