Syntax
track ip interface
To remove the tracking feature from the VLAN, use the no track ip interface command.
Parameters
interface Enter the following keywords and slot/port or number information:
• For a Port Channel interface, enter the keywords port-channel then a number.
The range is from 1 to 128.
• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then

Command History
Version Description
9.9(0.0) Introduced on the FN IOM.
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information
When this command is congured, the VLAN is operationally UP if any of the interfaces specied in the track
ip command are operationally UP, and the VLAN is operationally DOWN if none of the tracking interfaces are
operationally UP.
If the track ip command is not congured, the VLAN's Layer 3 operational state depends on all the members of
the VLAN.
The Layer 2 state of the VLAN, and hence the Layer 2 trac, is not aected by the track ip command
conguration.
