Description
Feature
With OAM enabled, TLPT with automatic link
restoration is available for the copper ports on the local
and remote peer Devices. When a copper port goes
“down,” the information is passed to the other Device
and the copper port on that Device will go “down.”
When the link is restored, the link on the other port is
also restored—the fiber ports remain UP. When TLPT is
disabled, if the copper port link drops it does not affect
its peer’s copper port links.

Auto Link Restoration
Note: In the redundant
models (SFBRM1040-
1xx) this feature only
works when the Device
is in redundant mode.
Auto Link Restoration
will restore the broken link
automatically upon correcting the fault condition.
For TLPT disabled and enabled scenarios, see the
illustrations below.
The feature monitors the fiber Rx port for signal loss. If
the fiber Rx goes “down,” the copper port stops
transmitting. See illustration below.
