error-disabled state, or the switch is reloading. It can respond to but not 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.
To configure an Ethernet OAM template and to associate it with an interface, follow these steps:
Command Purpose
Step 1
Switch# configure terminal
Enters global configuration mode.
Step 2
Switch(config)# template template-name
Creates a template and enters template configuration mode.
Step 3
Switch(config-template)# ethernet oam
link-monitor receive-crc
{threshold {high
{high-frames | none} | low {low-frames}} | window
milliseconds
}
(Optional) Configures thresholds for monitoring ingress
frames received with cyclic redundancy code (CRC) errors
for a period of time.
• Enter threshold high high-frames to set a high
threshold for the number of frames received with CRC
errors. The range is 1 to 65535 frames.
• Enter threshold high none to disable the high
threshold.
• Enter threshold low low-frames to set a low threshold
in number of frames. The range is 0 to 65535. The
default is 1.
• Enter window milliseconds to set the a window and
period of time during which frames with CRC errors
are counted. The range is 10 to 1800 and represents the
number of milliseconds in multiples of 100. The
default is 100.
