Purpose Command or Action
Enables Ethernet OAM. ethernet oam [ max-rate oampdus | min-rate num-seconds | mode
{ active | passive } | timeout seconds ]
Step 4
Example:
Device(config-if)# ethernet oam
Configures a number for error frames that when
reached triggers an action.
ethernet oam link-monitor frame
{
threshold
{
high
{
none
|
high-frames } | low low-frames } | window milliseconds }
Step 5
Example:
Device(config-if)# ethernet oam link-monitor frame window
399
Configures a number of frames to be polled. ethernet oam link-monitor frame-period { threshold { high { none
| high-frames } |
low low-frames
} |
window frames
}
Step 6
Frame period is a user-defined parameter.
Example:
Device(config-if)# ethernet oam link-monitor frame-period
threshold high 599
Configures a period of time in which error frames
are counted. ethernet oam link-monitor frame-seconds { threshold { high
{ none | high-frames } | low low-frames } | window milliseconds }
Step 7
Example:
Device(config-if)# ethernet oam link-monitor frame-seconds
window 699
Configures an Ethernet OAM interface to monitor
ingress frames with cyclic redundancy check
(CRC) errors for a period of time.
ethernet oam link-monitor receive-crc
{
threshold
{
high
{ high-frames | none } | low low-frames } | window milliseconds }
Example:
Device(config-if)# ethernet oam link-monitor receive-crc
window 99
Step 8
Configures an Ethernet OAM interface to monitor
egress frames with CRC errors for a period of
time. ethernet oam link-monitor transmit-crc { threshold { high
{ high-frames | none } | low low-frames } | window milliseconds }
Example:
Device(config-if)# ethernet oam link-monitor transmit-crc
threshold low 199
