OAM Commands
efm oam remote-loopback
This command starts or stops OAM loopback test mode to the attached CPE.
Syntax
efm oam remote-loopback {start | stop} interface
start - Starts remote loopback test mode.
stop - Stops remote loopback test mode.
interface - unit/port
unit - Unit identifier. (Range: 1)
port - Port number. (Range: 1-12)
Default Setting
None
Command Mode
Privileged Exec
Command Usage
• OAM remote loop back can be used for fault localization and link performance testing.
Statistics from both the local and remote DTE can be queried and compared at any time during
loop back testing.
• Use the efm oam remote-loopback start command to start OAM remote loop back test mode
on the specified port. Afterwards, use the command
“efm oam remote-loopback test” on
page 575 to start sending test packets. Then use the efm oam remote loopback stop
command to terminate testing (if test packets are still being sent) and to terminate loop back
test mode.
• The port that you specify to run this test must be connected to a peer OAM device capable of
entering into OAM remote loopback mode. During a remote loopback test, the remote OAM
entity loops back every frame except for OAMPDUs and pause frames.
• During loopback testing, both the switch and remote device are permitted to send OAMPDUs to
the peer device and to process any OAMPDUs received from the peer.
Example
Console#efm oam remote-loopback start 1/1
