Parameters
track-entry-number: Specifies the track entry ID in the range of 1 to 1024.
interface interface-type interface-number: Specifies the output interface by its type and number of the BFD echo packets.
remote ip remote-ip: Specifies the destination IP address of the BFD echo packets.
local ip local-ip: Specifies the source IP address of the BFD echo packets.
delay: Specifies the delay before the Track module notifies the application modules of the track entry state change. If you do not specify this keyword, the Track module notifies the application modules immediately when the track entry state changes.
negative negative-time: Specifies the delay before the Track module notifies the application modules that the status of the track entry has changed to Negative. The negative-time argument represents the delay time in the range of 1 to 300 seconds.
positive positive-time: Specifies the delay before the Track module notifies the application modules that the status of the track entry has changed to Positive. The positive-time argument represents the delay time in the range of 1 to 300 seconds.
Usage guidelines
After a track entry is created, you can only use the track bfd delay command to modify its notification delay settings. To modify other settings, you must delete the entry and create a new one.
When you configure collaboration between Track and BFD, do not configure the virtual IP address of a VRRP group as the local or remote address of a BFD session.
Examples
# Create track entry 1, which uses BFD to monitor the link between local IP address 1.1.1.2 and remote IP address 1.1.1.1 by sending BFD echo packets out from the VLAN-interface 2.
<Sysname> system-view
[Sysname] track 1 bfd echo interface vlan-interface 2 remote ip 1.1.1.1 local ip 1.1.1.2

negative negative-time: Specifies the delay before the Track module notifies the application modules that the status of the track entry has changed to Negative. The negative-time argument represents the delay time in the range of 1 to 300 seconds.
positive positive-time: Specifies the delay before the Track module notifies the application modules that the status of the track entry has changed to Positive. The positive-time argument represents the delay time in the range of 1 to 300 seconds.
Usage guidelines
After a track entry is created, you can only use the track cfd delay command to modify its notification delay settings. To modify other settings, you must delete the entry and create a new one.
Examples
# Create track entry 1, and specify the CFD service instance ID as 2 and MEP ID as 3.

Parameters
track-entry-number: Specifies the track entry ID in the range of 1 to 1024.
interface-type interface-number: Specifies an interface by its type and number.
delay: Specifies the delay before the Track module notifies the application modules of the track entry state change. If you do not specify this keyword, the Track module notifies the application modules immediately when the track entry state changes.
negative negative-time: Specifies the delay before the Track module notifies the application modules that the state of the track entry has changed to Negative. The negative-time argument represents the delay time in the range of 1 to 300 seconds.
positive positive-time: Specifies the delay before the Track module notifies the application modules that the state of the track entry has changed to Positive. The positive-time argument represents the delay time in the range of 1 to 300 seconds.
Usage guidelines
When you create a track entry that is associated with the link state of a specific interface, the state of the track entry is Positive if the link state of the interface is up. The state of the track entry is Negative if the link state of the interface is down.
To display the link state of an interface, use the display ip interface brief command.
After you create a track entry, you can only use the track interface delay command to modify its notification delay settings. To modify other settings, you must delete the entry and create a new one.
Examples
# Create track entry 1, and associate it with the link state of VLAN-interface 10.
