Chapter 20 Checking Status and Connectivity
To specify the OAM port mode on the specified ports, perform this task in privileged mode:
Task
Specify the OAM port mode on the specified
ports.
This example shows how to specify the OAM port mode to active on the specified port:
Console> (enable) set port ethernet-oam 3/1 mode active
Successfully updated OAM mode to active on port(s) 3/1.
Console> (enable)
Denying or Permitting Ethernet OAM Remote Loopback Tests
You can use the commands in this section to deny or permit an OAM remote loopback request on the
specified ports. The default is permit.
To deny or permit an OAM remote loopback request on the specified ports, perform this task in
privileged mode:
Task
Deny or permit an OAM remote loopback request
on the specified ports.
This example shows how to deny an OAM remote loopback request on the specified port:
Console> (enable) set port ethernet-oam 3/1 remote-loopback deny
Successfully updated OAM remote-loopback capability to deny on port(s) 3/1.
Console> (enable)
Enabling or Disabling the Ethernet OAM Remote Loopback Test
You can use the commands in this section to enable or disable the OAM remote loopback test on the
specified ports. The ports that you specify to run this test must be connected to a peer OAM device that
is capable of entering into the OAM remote loopback mode.
The commands in this section are not saved in your configuration file or NVRAM.
Note
Note During a remote loopback test operation, all packets including data packets are dropped at the port when
remote loopback is enabled. This behavior results in many protocols (such as STP, EtherChannel
protocols, and so on) resetting their state machines.
