Configuring Ethernet OAM
Step 3
ethernet oam link-monitor receive-crc
{threshold {high {high-frames | none} | low
{low-frames}} | window milliseconds}
(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 4
ethernet oam link-monitor symbol-period
{threshold {high {high symbols | none} | low
{low-symbols}} | window symbols}
(Optional) Configure high and low thresholds for an
error-symbol period that triggers an error-symbol
period link event.
• Enter threshold high high-symbols to set a high
threshold in number of symbols. The range is 1
to 65535.
• Enter threshold high none to disable the high
threshold.
• Enter threshold low low-symbols to set a low
threshold in number of symbols. The range is 0
to 65535. It must be lower than the high
threshold.
• Enter window symbols to set the window size
(in number of symbols) of the polling period.
The range is 1 to 65535 symbols.
