show ip bfd interfaces

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

Syntax

Command Parameters

{slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}

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), or a series of slots and ports (slot/port,slot/port,slot/port). 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.
This parameter does not apply to all hardware platforms.

Table 1.

Output field

Description

VLAN

Specifies the VLAN ID. This field appears only in output for VLAN interfaces.

PORT

Specifies the port number. This field appears only in output for GigabitEthernet interfaces.

INTF ID

Specifies the loopback interface ID. This field appears only in output for Loopback interfaces.

This parameter does not apply to all hardware platforms.

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.
