R3303-HP HSR6800 Routers High Availability Configuration Guide

# Display the Ethernet OAM configuration on Router A.

[RouterA] display oam configuration

Configuration of the link event window/threshold :

--------------------------------------------------------------------------

Errored-symbol Event period(in seconds) : 1

Errored-symbol Event threshold : 1

Errored-frame Event period(in seconds) : 20

Errored-frame Event threshold : 10

Errored-frame-period Event period(in ms) : 1000

Errored-frame-period Event threshold : 1

Errored-frame-seconds Event period(in seconds) : 60

Errored-frame-seconds Event threshold : 1

Configuration of the timer :

--------------------------------------------------------------------------

Hello timer(in ms) : 1000

Keepalive timer(in ms) : 5000

The output shows that the detection period of errored frame events is 20 seconds, the detection

threshold is 10 seconds, and all the other parameters use the default values.

You can use the display oam critical-event command to display the statistics of Ethernet OAM

critical link events. For example:

# Display the statistics of Ethernet OAM critical link events on all the ports of Router A.

[RouterA] display oam critical-event

Port : GigabitEthernet3/0/1

Link Status : Up

Event statistic :

-------------------------------------------------------------------------

Link Fault :0 Dying Gasp : 0 Critical Event : 0

The output shows that no critical link event occurred on the link between Router A and Router B.

You can use the display oam link-event command to display the statistics of Ethernet OAM link

error events. For example:

# Display Ethernet OAM link event statistics of the remote end of Router B.

[RouterB] display oam link-event remote

Port :GigabitEthernet3/0/1

Link Status :Up

OAMRemoteErrFrameEvent : (ms = milliseconds)

---------------------------------------------------------------------

Event Time Stamp : 5789 Errored Frame Window : 10(100ms)

Errored Frame Threshold : 1 Errored Frame : 3

Error Running Total : 35 Event Running Total : 17

The output shows that 35 errors occurred since Ethernet OAM was enabled on Router A, 17 of

which were caused by error frames. The link is unstable.
