Link dependency
Link dependency lets you enable or disable one or more interfaces based on the link
state of one or more
other interfaces. That is, if you enable link dependency on an
interface, the link state of that interface depends on the link state of another interface.
For example, if port 0/2 depends on port 0/4 and the switch detects a link loss on port
0/4, the switch can automatically bring down the link on port 0/2. When the link is
restored on port 0/4, the switch can automatically restore the link on port 0/2.
The other way around is also possible: If port 0/2 depends on port 0/4 and the switch
detects a link loss on port 0/4, the switch can automatically bring up the link on port
0/2. When the link is restored on port 0/4, the switch can automatically bring down the
link on port 0/2.
Configure a link dependency group
A link dependency group includes a list of upstream interfaces, a list of downstream
interfaces, and an action that is configured for the group. If all upstream interfaces in
the list go down, all downstream interfaces in the list are either brought down or brought
up, depending on the action that you configure for the link dependency group.
After you configure the link dependency group, configure the upstream and downstream
interfaces for the group (see Configure or display upstream and downstream interfaces
for a link dependency group on page 180).
To configure a link dependency group:
1. Launch a web browser.
2. In the address field of your web browser, enter the IP address of the switch.
The login page displays.
3. Click the Main UI Login button.
The main UI login page displays in a new tab.
4. Enter admin as the user name, enter your local device password, and click the Login
button.
