Chapter 41 Configuring Ethernet OAM, CFM, and E-LMI
Setting Up and Configuring Ethernet OAM
The ethernet oam link-monitor transmit-crc {threshold {high {high-frames | none} | low
{low-frames}} | window milliseconds} command is visible on the switch and you are allowed to enter
it, but it is not supported.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.
