Configuring Link-State

The following procedure lists the steps to configure a Link-State entry. Refer to the S-, K-, and 7100 Series CLI Reference Guide for details about using the commands listed.

Configuring Link-State Entries

Step	Task	Command(s)
1	In configuration mode, create the tracked object for the desired uplink ports.	Refer to the “Tracked Object Manager Configuration” chapter.
2	Create the Link-State entry that associates the tracked object with the desired downstream ports.	set link-state track object-name downstream port-string
3	Optionally, display information about the Link-State entry.	show link-state [object-name [detail]]
4	Enable force link down on the switch.	set forcelinkdown enable

This example creates a port-group tracked object named ls_group, changes the defaults for up/down status message delays for the object, gives the tracked object a description and puts it in service, then configures the Link-State application to use that tracked object and associate it with downstream ports. Force link down is then enabled on the switch.
