Platforms Supported

Usage Guidelines
• Before issuing this command, the LINK OAM port has to be in active mode and discovery of peer
ports has to be completed.
• When loopback is started from a port towards a peer port which is configured to ignore the loopback
request, the loopback response timer will timeout and no error is displayed. In such case, verify the
loopback-state of two ports by using the command show efm-oam port remote detail.
• The maximum number of simultaneous loopback sessions supported per network interface is 2. If a
third loopback is started through CLI, an error will be displayed at the CLI prompt.
Examples
-> efm-oam port 1/1 remote-loopback start
