Chapter 39 Configuring Ethernet OAM, CFM, and E-LMI
Setting Up and Configuring Ethernet OAM
Beginning in privileged EXEC mode, follow these steps to configure an Ethernet OAM template and to
associate it with an interface:
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 template template-name Create a template, and enter template configuration mode.
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.
