disable this function.
Syntax

Default Setting
Disabled

Command Usage
â—† If the remote device also supports OAM, both exchange Information OAMPDUs
to establish an OAM link.
â—† Not all CPEs support OAM functions, and OAM is therefore disabled by default.
If the CPE attached to a port supports OAM, then this functionality must first be
enabled by the efm oam command to gain access to other remote
configuration functions.
Example
Console(config)#interface ethernet 1/1
Console(config-if)#efm oam
Console(config-if)#
efm oam
critical-link-event
This command enables reporting of critical event or dying gasp. Use the no form to
disable this function.
Syntax
[no] efm oam critical-link-event {critical-event | dying-gasp}
critical-event - If a critical event occurs, the local OAM entity (this switch)
indicates this to its peer by setting the appropriate flag in the next
OAMPDU to be sent and stores this information in its OAM event log.
dying-gasp - If an unrecoverable condition occurs, the local OAM entity
indicates this by immediately sending a trap message.
