Default Link-State Tracking Configuration

There are no link-state groups defined, and link-state tracking is not enabled for any group.

Configuring Link-State Tracking
Beginning in privileged EXEC mode, follow these steps to configure a link-state group and to assign an
interface to a group:
Command
Step 1 configure terminal
Step 2 link state track number
Step 3 interface interface-id
Step 4 link state group [number] {upstream |
downstream}
Step 5
end
Step 6 show running-config
Step 7 copy running-config startup-config

An interface that is defined as an upstream interface cannot also be defined as a downstream
interface in the same or a different link-state group. The reverse is also true.
An interface cannot be a member of more than one link-state group.
You can configure only two link-state groups per switch.
Purpose
Enter global configuration mode.
Create a link-state group, and enable link-state tracking. The
group number can be 1 to 2. The default is 1.
Specify a physical interface or range of interfaces to configure,
and enter interface configuration mode.
Valid interfaces include switch ports in access or trunk mode
(IEEE 802.1q), routed ports, or multiple ports bundled into an
EtherChannel interface (static or LACP) that is also in trunk
mode.
Specify a link-state group, and configure the interface as either
an upstream or downstream interface in the group. The group
number can be 1 to 2. The default is 1.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
