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

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.
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.
User EXEC
The show ip bfd interfaces command displays the following information:
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. |
The following example displays VLAN interface configuration information for BFD.
