efm oam
This command enables OAM functions on the specified port. Use the no form to
disable this function.
Syntax
[ no ] efm oam
Default Setting
Disabled
Command Mode
Interface Configuration
Command Usage
◆
If the remote device also supports OAM, both exchange Information OAMPDUs
to establish an OAM link.
◆
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
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.
Default Setting
Enabled
Command Mode
Interface Configuration
Command Usage
◆
Critical events are vendor-specific and may include various failures, such as
abnormal voltage fluctuations, out-of-range temperature detected, fan failure,
CRC error in flash memory, insufficient memory, or other hardware faults.
