CLI: Link State Mirroring
You can use the link-state command to configure link state mirroring. If link state mirroring is enabled, bridge port states will be synchronized. For example, if one port's link is down, the other port will be manually forced into the link down state. If link state mirroring is enabled, it applies to all bridge interfaces.
ipmi {enable|ip|dhcp|username|sel|seltime|power}
To enable link state mirroring:
[no] link-state enable
To set the delay in ms before an interface is forced into the down state or is returned to the up state:
link-state {down-delay|up-delay} <duration_ms>
To show the current link state configuration:
show link-state
