Configuring Ethernet OAM
EXAMPLE
Switch(config)# interface gigabitEthernet 3/8
Switch(config-if)#
Switch(config-if)# ethernet oam
Switch(config-if)# ethernet oam link-monitor symbol-period threshold high 299
Switch(config-if)# ethernet oam link-monitor frame window 399
Switch(config-if)# ethernet oam link-monitor frame-period threshold high 599
Switch(config-if)# ethernet oam link-monitor frame-seconds window 699
Switch(config-if)# ethernet oam link-monitor receive-crc window 99
Switch(config-if)# exit
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.
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. The switch can also respond to and generate
Dying Gasp PDUs based on loss of power.
BEFORE YOU BEGIN
Review the “Information About the Ethernet OAM Protocol” section on page 17-34.
DETAILED STEPS
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface interface-id Define an interface, and enter interface
configuration mode.
Step 3
ethernet oam remote-failure {critical-event |
dying-gasp | link-fault} action
error-disable-interface
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.
Step 4
end Return to privileged EXEC mode.
