Chapter 10 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 the threshold high high-frames command to set
a high threshold for the number of frames received
with CRC errors. The range is 1 to 65535 frames.
• Enter the threshold high none command to disable the
high threshold.
• Enter the threshold low low-frames command to set a
low threshold in number of frames. The range is 0 to
65535. The default is 1.
• Enter the window milliseconds command 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 the threshold high high-symbols command to
set a high threshold in number of symbols. The range
is 1 to 65535.
• Enter the threshold high none command to disable the
high threshold.
• Enter the threshold low low-symbols command to set
a low threshold in number of symbols. The range is 0
to 65535. It must be lower than the high threshold.
• Enter the window symbols command to set the window
size (in number of symbols) of the polling period. The
range is 1 to 65535 symbols.
Step 5
ethernet oam link-monitor frame {threshold {high
{high-frames | none} | low {low-frames}} | window
milliseconds}
(Optional) Configure high and low thresholds for error
frames that trigger an error-frame link event.
• Enter the threshold high high-frames command to set
a high threshold in number of frames. The range is 1 to
65535. You must enter a high threshold.
• Enter the threshold high none command to disable the
high threshold.
• Enter the threshold low low-frames command to set a
low threshold in number of frames. The range is 0 to
65535. The default is 1.
• Enter the window milliseconds command to set the a
window and period of time during which error frames
are counted. The range is 10 to 600 and represents the
number of milliseconds in a multiple of 100. The
default is 100.
