Command or Action
Step 4
ethernet oam link-monitor receive-crc {threshold {high
{high-frames | none} | low low-frames} | window milliseconds}
Example:
Device(config-template)# ethernet oam link-monitor
receive-crc window 99
Step 5 ethernet oam link-monitor transmit-crc {threshold {high
{high-frames | none} | low low-frames} | window milliseconds}
Example:
Device(config-template)# ethernet oam link-monitor
transmit-crc threshold low 199
Step 6 ethernet oam link-monitor symbol-period {threshold {high
{none | high-symbols} | low low-symbols} | window symbols}
Example:
Device(config-template)# ethernet oam link-monitor
symbol-period threshold high 299
Step 7 ethernet oam link-monitor frame {threshold {high {none |
high-frames} | low low-frames} | window milliseconds}
Example:
Device(config-template)# ethernet oam link-monitor
frame window 399
Step 8
ethernet oam link-monitor frame-period {threshold {high
{none | high-frames} | low low-frames} | window frames}
Example:
Device(config-template)# ethernet oam link-monitor
frame-period threshold high 599
Step 9 ethernet oam link-monitor frame-seconds {threshold {high
{none | high-frames} | low low-frames} | window milliseconds}
Example:
Device(config-template)# ethernet oam link-monitor
frame-seconds window 699
Step 10 exit
Example:
Device(config-template)# exit

Using Ethernet Operations Administration and Maintenance
Purpose
Configures an Ethernet OAM interface to monitor
ingress frames with CRC errors for a period of
time.
Configures an Ethernet OAM interface to monitor
egress frames with CRC errors for a period of time.
Configures a threshold or window for error
symbols, in number of symbols.
Configures a number for error frames that when
reached triggers an action.
Configures a number of frames to be polled.
Frame period is a user-defined parameter.
Configures a period of time in which error frames
are counted.
Returns to global configuration mode.
