Use the undo oam ethernet errored-frame-period threshold command to restore the default value.

If the number of error frames detected on a port over a detection interval is equal to or greater than the error threshold, an error frame period event is created. The default detection interval equals the maximum number of the minimum-length frames that can be received by the switch within 1000 milliseconds.

After the OAM connection is established, the configured values take effect on all the Ethernet ports automatically.

1.1.21 oam ethernet loopback

Syntax

oam ethernet loopback

undo oam ethernet loopback

View

Ethernet port view

Parameters

None

Description

Use the oam ethernet loopback command to trigger remote loopback control on an Ethernet port.

Use the undo oam ethernet loopback command to remove the configuration.

Once the oam ethernet loopback command is executed, the local endpoint sends the remote loopback command to the remote endpoint. OAM loopback of the local endpoint enters the LB_EN_DISCARD state. If remote loopback succeeds, the remote endpoint returns the acknowledgment message and enters the LB_UNDERCTL state. After receiving the acknowledgment message, the local endpoint enters the LB_CTL state. If loopback fails, the local endpoint enters the normal state and cancels loopback settings. The undo oam ethernet loopback command enables the local endpoint to send the command for canceling remote loopback. After remote loopback succeeds, the local endpoint and the remote endpoint enter the LB_DISABLE state.

You can perform remote loopback only after the establishment of the OAM connection. If the connection is interrupted during loopback, remote loopback will be cancelled automatically. The port enters the LB_DISABLE state.

Related commands: display oam ethernet loopback status.

Examples

# Enable remote loopback on the peer endpoint of Ethernet 1/1/1.

1.1.22 oam ethernet mode

Parameters

active: Active mode

passive: Passive mode

Description

Use the oam ethernet mode command to set the OAM mode on the current Ethernet port.

Use the undo oam ethernet mode command to restore the default value, that is, active mode.

By default, OAM is set to the active mode.

The OAM connection cannot be established between two ports in the passive mode.

After the OAM function is enabled, that is, after the oam ethernet enable command is input, you are not allowed to change the OAM mode. If you need to change the OAM mode, you can disable the OAM function first, and then change the OAM mode.

Related commands: oam ethernet enable.

Parameters

interval: Interval of sending Ethernet OAM hello PDUs (in milliseconds). This argument ranges from 500 to 5000 and must be a multiple of 500.

Description

Use the oam ethernet timer hello command to set the interval of sending Ethernet OAM hello PDUs, which are used to maintain OAM connections.

Use the undo oam ethernet timer hello command to restore the interval of sending Ethernet OAM hello PDUs to the default value.

By default, the interval of sending Ethernet OAM hello PDUs is 1,000 ms.

Examples

# Set the interval of sending Ethernet OAM hello PDUs to 3000 milliseconds.

1.1.24 oam ethernet timer keepalive

Syntax

undo oam ethernet timer keepalive

View

Parameters

interval: Ethernet OAM link timeout time. This argument ranges from 500 to 25000 (in milliseconds) and must be a multiple of 500.

Description

Use the oam ethernet timer keepalive command to set the Ethernet OAM link timeout time.

Use the undo oam ethernet timer keepalive command to restore the Ethernet OAM link timeout time to the default value.

By default, the Ethernet OAM link timeout time is 5000 ms.

Examples

# Set the Ethernet OAM link timeout time to 2000 milliseconds.

<H3C> system-view

[H3C] oam ethernet timer keepalive 2000

& Note:

After an Ethernet OAM link times out, the local end of the Ethernet OAM will age its connection to the remote OAM entity. Consequently, the OAM link disconnects. In normal conditions, you are recommended to set the timeout time to be longer than the interval of sending Ethernet OAM hello PDUs. Otherwise, a link may disconnect before Ethernet OAM hello PDUs are received, thus causing link instability.
