Chapter 66 Configuring Ethernet OAM and CFM
To configure Ethernet OAM link monitoring on an interface, perform this task:
Command
Step 1
Switch# configure terminal
Step 2
Switch(config)# interface interface-id
Step 3
Switch(config-if)# ethernet oam link-monitor
supported
Step 4
Switch(config-if)# ethernet oam link-monitor

} | {
none low low-symbols
Repeat this step to configure both high and low
thresholds.
Step 5
Switch(config-if)# ethernet oam link-monitor
{
frame threshold
{
low low-frames
Repeat this step to configure both high and low
thresholds.

Purpose
Enters global configuration mode.
Defines an interface, and enters interface configuration
mode.
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.
(Optional) Configures high and low thresholds for an

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.
(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.
