track
To configure an interface to be tracked where the Gateway Load Balancing Protocol (GLBP) weighting
changes based on the state of the interface, use the
track
command in global configuration mode. To remove
the tracking, use the
no
form of this command.

Syntax Description
Object number in the range from 1 to 1000
representing the interface to be tracked.
object-number
Interface type and number to be tracked.
interface type number
Tracks whether the interface is up.
line-protocol
Tracks whether IP routing is enabled, an IP address
is configured on the interface, and the interface state
is up, before reporting to GLBP that the interface is
up.
ip routing
Tracks whether IPv6 routing is enabled, an IP address
is configured on the interface, and the interface state
is up, before reporting to GLBP that the interface is
up.
ipv6 routing
Command Default
The state of the interfaces is not tracked.
Command Modes
Global configuration (config)
Usage Guidelines
Use the
track
command in conjunction with the
glbp weighting
and
glbp weighting track
commands to
configure parameters for an interface to be tracked. If a tracked interface on a GLBP device goes down, the
weighting for that device is reduced. If the weighting falls below a specified minimum, the device will lose
its ability to act as an active GLBP virtual forwarder.
A maximum of 1000 objects can be tracked. Although 1000 tracked objects can be configured, each tracked
object uses CPU resources. The amount of available CPU resources on a device is dependent upon variables
such as traffic load and how other protocols are configured and run. The ability to use 1000 tracked objects
is dependent upon the available CPU. Testing should be conducted on site to ensure that the service works
under the specific site traffic conditions.
Examples
In the following example, TenGigabitEthernet interface 0/0/1 tracks whether GigabitEthernet interfaces 1/0/1
and 1/0/3 are up. If either of the GigabitEthernet interface goes down, the GLBP weighting is reduced by the
