LINK OAM Commands
OmniSwitch 6250 CLI Reference Guide November 2009 page 26-15
efm-oam port propagate-events
Configures whether or not the specified port or range of ports will propagate local event notifications to
the remote peer.
efm-oam port slot/port[-port2] propagate-events {critical-event | dying-gasp} {enable | disable}
Syntax Definitions
slot/port The slot number for the module and the physical port number on that
module (e.g. 3/1 specifies port 1 on slot 3).
-port2 Specifies the last port in the range of ports.
critical-event Configures the notification status for critical events.
dying-gasp Configures the notification status for dying gasp events.
enable Enables the notification of critical-event or dying-gasp events to the
peer.
disable Disables the notification of critical-event or dying-gasp events to the
peer.
Defaults
By default, the notification status for both critical-event and dying-gasp events is set to enabled.
Platforms Supported
OmniSwitch 6250.
Usage Guidelines
•
When the system is set for critical event or a dying-gasp event, the local OAM entity indicates the
event through the OAMPDU flags to its peer OAM entity.
•
In case of port admin down, the OAM IFU-PDU with dying-gasp bit set will be sent to peer as soon as
a failure is detected and transmission will continue till the specific port actually goes down.
•
In case of takeover or reload of the switch, the OAM IFU-PDU with dying-gasp bit set will be sent to
peer as soon as a failure is detected and transmission will continue till the specific device actually goes
down.
•
The information PDUs with dying gasp bit set is transmitted towards peer as soon as link-down is
detected at NI. However, if there is a link flap (i.e link comes again) before the expiry of link-flap
timer, then normal information PDU transmission with dying-gasp bit reset shall resume. This will
cause clearing of alarms or trap on the peer port.
