Configuring Ethernet OAM
Configuring Ethernet OAM Link Monitoring
You can configure high and low thresholds for link-monitoring features. If no high threshold is
configured, the default is none —no high threshold is set. If you do not set a low threshold, it defaults
to a value lower than the high threshold.
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.
BEFORE YOU BEGIN
Review the “Information About the Ethernet OAM Protocol” section on page 17-34.
DETAILED STEPS
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface interface-id Define an interface, and enter interface
configuration mode.
Step 3
ethernet oam link-monitor supported Enable the interface to support link monitoring. This
is the default.
You need to enter this command only if it has been
disabled by previously entering the no ethernet oam
link-monitor supported command.
Step 4
ethernet oam link-monitor symbol-period
{threshold {high {high symbols | none} | low
{low-symbols}} | window symbols}
Note Repeat this step to configure both high
and low thresholds.
(Optional) Configure high and low thresholds for an
error-symbol period that trigger 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. 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-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.
