Feature Description
Last Gasp/Dying
Gasp(OAM, IEEE
802.3ah-2004 standard)
All FBRM/BFFG Devices come equipped with a Last
Gasp/OAM Dying Gasp feature. This feature enables
the Device to store a small amount of power to enable
sending an SNMP trap to alert the management console
of a power failure. Feature benefits are the following:
• Notification of an impending power loss before it
happens
• Allows for quicker resolution of the power loss
The default action for last gasp/OAM dying gasp is to
send an SNMP Trap. If the desire is to send a dying
gasp through OAM, it must be configured through the
SNMP/Web interface. It requires choosing the port on
which to send the Dying Gasp command since both
ports are OAM capable. This feature helps
communicate with OAM peers that are not TN Devices.
Remote Loop Back
(OAM, IEEE 802.3ah-
2004 standard)
OAM remote loop back can be used to test link health
by sending a loop back request from the active peer
Device to the remote passive peer Device. Once the
remote passive peer enters loop back mode, all frames
coming into that port are looped back, yet not forwarded
to other ports.
The OAM frames are still exchanged between the local
and remote peer Devices—only OAM frames get
through. The active peer Device discards the frames
coming out of its remote peer Device to prevent
flooding the network. See the illustration below.
Alternate Loop back This feature can be used to verify end-to-end
connectivity.
