OcNOS-SP : Layer 3 Guide : Bidirectional Forwarding Detection Command Reference : Bidirectional Forwarding Commands : show bfd interface
show bfd interface
Use this command to display details for an interface running BFD or for all interfaces configured for BFD.
Command Syntax
show bfd interface (ifindex <0-4294967295>|all|)
Parameters
all
Display all interfaces.
ifindex
Display an interface index.
<0-4294967295>
 
Display an ID of an interface in this range.
Command Mode
Exec mode and Privileged Exec mode
Applicability
This command was introduced before OcNOS version 1.3.
Example
The example below displays the command syntax and sample output from the command.
#show bfd interface all

Table 1-86: show BFD interface fields
Entry
Description
interface
Interface on which BFD is running
ifindex
Interface index number
state
State of the BFD session for the interface:
 
UP: session is up.
DOWN: session is down
Interface level configuration
State of interface-level properties:
 
echo on or off
slow-timer (timer dampening) on or off
Min Tx
The minimum interval that the local device would like to use when transmitting BFD control packets.
Min Rx
The minimum interval between received BFD control packets that this device is capable of supporting
Multiplier
The negotiated transmit interval, multiplied by this value, provides the detection time for the receiving device in asynchronous mode.
