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
efm oam remote-loopback test command
( page 568 ) 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
Loopback operation is processing, please wait.
Enter loopback mode succeeded.
Console#
efm oam remote-loopback test
This command performs a remote loopback test, sending a specified number of packets.
