Ethernet Interface Configuration Mode Commands

Mode

The Ethernet Interface Configuration Mode is used to create and manage Ethernet IP interface parameters within a specified context.

Exec > Global Configuration > Context Configuration > Ethernet Interface Configuration

configure > context context_name > interface interface_name broadcast

Entering the above command sequence results in the following prompt:

Mode

Exec > Global Configuration > Context Configuration > Ethernet Interface Configuration

configure > context context_name > interface interface_name broadcast

Entering the above command sequence results in the following prompt: 

[context_name]host_name(config-if-eth)#

Syntax

[no ] bfd  { echo  [echo-interval  interval_num] | interval  interval_num } 
    min_rx  milliseconds multiplier  value

no

Disables the specified option on this interface.

echo

Enables BFD echo mode.

BFD echo mode works with asynchronous BFD. Echo packets are sent by the forwarding engine and forwarded back along the same path in order to perform detection—the BFD session at the other end does not participate in the actual forwarding of the echo packets. The echo function and the forwarding engine are responsible for the detection process, therefore the number of BFD control packets that are sent out between two BFD neighbors is reduced.

Since the forwarding engine is testing the forwarding path on the remote (neighbor) system without involving the remote system, there is an opportunity to improve the interpacket delay variance, thereby achieving quicker failure detection times than when using BFD Version 0 with BFD control packets for the BFD session.

echo-interval interval_num

Specifies the transmit interval between BFD echo packets. The default interval is 150 ms. The range is from 0 to 999 ms. (VPC only)

interval interval_num

Specifies the transmit interval (in milliseconds) between BFD packets.

  • For releases prior to 17.0, interval_num is an integer from 50 through 999. (Default 50)

  • For release 17.0 onwards, interval_num is an integer from 50 through 10000. (Default 50)

min_rx milliseconds

Specifies the receive interval in milliseconds for control packets.

  • For releases prior to 17.0, milliseconds is an integer from 50 through 999. (Default 50)

  • For release 17.0 onwards, milliseconds is an integer from 50 through 10000. (Default 50)

multiplier value

Specifies the value used to compute the hold-down time as a number from 3 to 50.

Usage Guidelines

Specify BFD parameters including echo mode and the transmit interval between BFD packets.

Example

To apply enable echo mode on this interface, use the following command: 
bfd echo
The following command sets BFD interval parameters: 
bfd interval 3000 min_rx 300 multiplier 3
