Parameters

window-value: Specifies the errored symbol event detection window in the range of 1 to 65535. The value of this argument must be a multiple of 1000000.

Usage guidelines

The configuration in system view takes effect on all ports, but has a lower precedence than the configuration in port view.

Examples

# Set the errored symbol event detection window to 200000000.

oam global timer hello

Use oam global timer hello to configure the global Ethernet OAM handshake packet transmission interval.

Use undo oam global timer hello to restore the default.

Syntax

oam global timer hello interval

undo oam global timer hello

Default

The global Ethernet OAM handshake packet transmission interval is 1000 milliseconds.

Views

System view

Predefined user roles

network-admin

Parameters

interval: Specifies the Ethernet OAM handshake packet transmission interval, in steps of 100 (in milliseconds). The value range for this argument is 500 to 5000.

Usage guidelines

After the timeout timer of an Ethernet OAM connection expires, the local OAM entity ages out its connection with the peer OAM entity, causing the OAM connection to disconnect. To keep the Ethernet OAM connections stable, H3C recommends that you set the connection timeout timer to be at least five times the handshake packet transmission interval.

The configuration in system view takes effect on all ports, but has a lower precedence than the configuration in port view.

Examples

# Set the Ethernet OAM handshake packet transmission interval to 600 milliseconds.

Parameters

active: Specifies the active Ethernet OAM mode.

passive: Specifies the passive Ethernet OAM mode.

Usage guidelines

To change the Ethernet OAM mode of an Ethernet OAM-enabled Ethernet port, first disable Ethernet OAM on the port.

Examples

# Disable Ethernet OAM on FortyGigE 1/1/1, and then configure FortyGigE 1/1/1 to operate in passive Ethernet OAM mode.

Parameters

connection-expired: Specifies a connection timeout fault.

oam remote-loopback

Use oam remote-loopback start to enable Ethernet OAM remote loopback on the specified Ethernet port.

Use oam remote-loopback stop to disable Ethernet OAM remote loopback on the Ethernet port.

Syntax

oam remote-loopback start

oam remote-loopback stop

Default

Ethernet OAM remote loopback is disabled on the Ethernet port.

Usage guidelines

Ethernet OAM remote loopback is available only after the Ethernet OAM connection is established and can be performed only by the Ethernet OAM entities operating in active Ethernet OAM mode.

You can enable Ethernet OAM remote loopback on a specified port in user view or system view, or enable it on the current port in port view. The configurations have the same effect.

Examples

# Configure the active Ethernet OAM mode and enable Ethernet OAM on FortyGigE 1/1/1, and then enable Ethernet OAM remote loopback on FortyGigE 1/1/1 in Layer 2 Ethernet port view.
