Configuring Ethernet OAM, CFM, and E-LMI
Configuring Ethernet OAM Remote Failure Indications
You can configure an error-disable action to occur on an interface if one of the high thresholds is
exceeded, if the remote link goes down, if the remote device is rebooted, or if the remote device disables
Ethernet OAM on the interface.
Beginning in privileged EXEC mode, follow these steps to enable Ethernet OAM remote-failure
indication actions on an interface:
Command
Step 1
configure terminal
Step 2
interface interface-id
Step 3
ethernet oam remote-failure {critical-event |
dying-gasp | link-fault} action
error-disable-interface
Step 4
end
Step 5
show ethernet oam status [interface interface-id]
Step 6
copy running-config startup-config
The switch does not generate Link Fault or Critical Event OAM PDUs. However, if these PDUs are
received from a link partner, they are processed. The switch supports sending and receiving Dying Gasp
OAM PDUs with reason codes when Ethernet OAM is disabled, the interface is shut down, the interface
enters the error-disabled state, or the switch is reloading. It can also respond to and generate, Dying Gasp
PDUs based on loss of power. Enter the no ethernet remote-failure {critical-event | dying-gasp |
link-fault} action command to disable the remote failure indication action.
Configuring Ethernet OAM Templates
You can create a template for configuring a common set of options on multiple Ethernet OAM interfaces.
The template can be configured to monitor frame errors, frame-period errors, frame-second errors,
received CRS errors, and symbol-period errors and thresholds. You can also set the template to put the
interface in error-disabled state if any high thresholds are exceeded. These steps are optional and can be
performed in any sequence or repeated to configure different options.
OL-23400-01
Purpose
Enter global configuration mode.
Define an interface, and enter interface configuration
mode.
Configure the Ethernet OAM remote-failure action on the
interface. You can configure disabling the interface for one
of these conditions:
Select critical-event to shut down the interface when
•
an unspecified critical event has occurred.
Select dying-gasp to shut down the interface when
•
Ethernet OAM is disabled or the interface enters the
error-disabled state.
•
Select link-fault to shut down the interface when the
receiver detects a loss of signal.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save your entries in the configuration file.
