Chapter 17 Configuring Ethernet OAM, CFM, and E-LMI
Configuring Ethernet OAM
Enter the no form of the commands to disable the configuration. Use the no form of each command to
disable the threshold setting.
Step 7
ethernet oam link-monitor frame-seconds
{threshold {high {high-frames | none} | low
{low-frames}} | window milliseconds}
Note Repeat this step to configure both high
and low thresholds.
(Optional) Configure high and low thresholds for the
frame-seconds error that triggers an
error-frame-seconds link event.
• Enter threshold high high-frames to set a high
error frame-seconds threshold in number of
seconds. The range is 1 to 900. The default is
none.
• Enter threshold high none to disable the high
threshold if it was set. This is the default.
• Enter threshold low low-frames to set a low
threshold in number of frames. The range is 1 to
900. The default is 1.
• Enter window frames to set the a polling
window size in number of milliseconds. The
range is 100 to 9000; each value is a multiple of
100 milliseconds. The default is 1000.
Step 8
ethernet oam link-monitor receive-crc
{threshold {high {high-frames | none} | low
{low-frames}} | window milliseconds}
Note Repeat this step to configure both high
and low thresholds.
(Optional) Configure 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.
Step 9
[no] ethernet link-monitor on (Optional) Start or stop (when the no keyword is
entered) link-monitoring operations on the interface.
Link monitoring operations start automatically when
support is enabled.
Step 10
end Return to privileged EXEC mode.
Step 11
show ethernet oam status [interface
interface-id]
Verify the configuration.
Step 12
copy running-config startup-config (Optional) Save your entries in the configuration
file.
