Chapter 75 Configuring Ethernet OAM and CFM
Enabling and Configuring Ethernet OAM
To configure Ethernet OAM link monitoring on an interface, perform this task:
Command Purpose
Step 1
Switch# configure terminal
Enters global configuration mode.
Step 2
Switch(config)# interface interface-id
Defines an interface, and enters interface configuration
mode.
Step 3
Switch(config-if)# ethernet oam link-monitor
supported
Enables the interface to support link monitoring. it 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
Switch(config-if)# ethernet oam link-monitor
symbol-period
{threshold {high {high symbols |
none} | low {low-symbols}} | window symbols}
Repeat this step to configure both high and low
thresholds.
(Optional) Configures 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. it 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.
Step 5
Switch(config-if)# ethernet oam link-monitor
frame
{threshold {high {high-frames | none} |
low
{low-frames}} | window milliseconds}
Repeat this step to configure both high and low
thresholds.
(Optional) Configures high and low thresholds for error
frames that trigger an error-frame link event.
• Enter threshold high high-frames to set a high
threshold in number of frames. The range is 1 to
65535. The default is none.
• Enter threshold high none to disable the high
threshold if it was set. it is the default.
• 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 error frames are counted.
The range is 10 to 600 and represents the number of
milliseconds in multiples of 100. The default is 100.
