Enabling hardware failure protection for interfaces
IMPORTANT:
Before enabling hardware failure protection on an interface, make sure a backup link is available for
service continuity.
After you enable hardware failure protection on an interface, the system automatically shuts down
the interface when it detects a hardware failure on the interface. An interface shut down this way is in
Protect Down state. After the failure on an interface is removed, bring the interface up by using the
undo shutdown command.
This feature does not take effect on an interface in the following situations:
•
Loopback testing is enabled (using the loopback { external | internal } command).
•
The interface is forcibly brought up (using the port up-mode command).
•
The interface is a physical IRF port.
To enable hardware failure protection for an interface:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Set the action to be taken in
response to failures on the
forwarding plane to
isolate .
hardware-failure-detection
forwarding isolate
By default, the system takes the
action of
warning (sending traps)
in response to forwarding-plane
failures.
3. Enter Ethernet interface
view.

4. Enable hardware failure
protection for the interface.

auto-down By default, hardware failure
protection is enabled.
Enabling hardware failure protection for aggregation groups
Hardware failure protection for aggregation groups uses the following rules upon detecting a
hardware failure on an aggregation group member interface:
•
Does not shut down the interface if the member interface is the only member in up state in the
group.
•
Shuts down the interface if the member interface is not the only member in up state in the
group.
This feature does not take effect on an interface in the following situations:
•
Loopback testing is enabled (by using the loopback { external | internal } command).
•
The interface is forcibly brought up (by using the port up-mode command).
•
The interface is a physical IRF port. For more information about physical IRF ports, see Virtual
Technologies Configuration Guide .
