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

By default, the errored frame period event detection interval is 1000 milliseconds.

For errored frame period event detection, the system first uses the following expression to convert the errored frame period event detection interval to the maximum number of 64-byte frames that can be transmitted through an Ethernet port in the period:

bandwidth * period / (64 * 8 * 1000),

where bandwidth is the port bandwidth (in bps) and “period” is the configured period (in milliseconds).

oam timer hello

Syntax

View

System view

Default level

2: System level

Parameters

interval: Ethernet OAM handshake packet transmission interval, in milliseconds. The value of this argument must be a multiple of 100, it ranges from 500 to 5000.

Description

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

Use the undo oam timer hello command to restore the default.

By default, the Ethernet OAM handshake packet transmission interval is 1000 milliseconds.

After the timeout timer for an Ethernet OAM connection expires, the local OAM entity ages out its connection with the peer OAM entity, causing the OAM connection to be disconnected. HP recommends that you set the connection timeout timer at least five times the handshake packet transmission interval, ensuring the stability of Ethernet OAM connections.

• Disable STP on the ports you want to add to the smart link group, and make sure that the ports are no

member ports of any aggregation group. On the other hand, you cannot enable STP on a smart link group member port or assign a smart link group member port to an aggregation group.

• You can assign a port to a smart link group with the port command in smart link group view.

Related commands: port.

Examples

# Configure Ethernet 1/0/1 as the master port of smart link group 1.

<Sysname> system-view [Sysname] smart-link group 1 [Sysname-smlk-group1] protected-vlan reference-instance 0 [Sysname-smlk-group1] quit [Sysname] interface ethernet 1/0/1 [Sysname-Ethernet1/0/1] undo stp enable [Sysname-Ethernet1/0/1] port smart-link group 1 master

# Configure Layer 2 aggregate interface 1 as the master port of smart link group 1.

preemption delay

Syntax

preemption delay delay-time

undo preemption delay

View

Smart link group view

Default level

2: System level

Parameters

delay-time: Preemption delay (in seconds), in the range of 0 to 300.

Description

Use the preemption delay command to set the preemption delay. When role preemption is enabled, after the preemption delay is set, the master port waits for some time before taking over, so as to collaborate with the switchover of upstream devices.

Use the undo preemption delay command to restore the default.

By default, the preemption delay is 1 second.

The preemption delay configuration takes effect only after role preemption is enabled.

Related commands: preemption mode.

Examples

# Enable role preemption and set the preemption delay to 10 seconds.

<Sysname> system-view [Sysname] smart-link group 1 [Sysname-smlk-group1] preemption mode role [Sysname-smlk-group1] preemption delay 10

preemption mode

Syntax

preemption mode role

undo preemption mode

View

Smart link group view

Default level

2: System level

Parameters

role: Configures the role preemption mode, which enables the master port to preempt the slave port in

active state.

Description

Use the preemption mode command to enable role preemption.

Use the undo preemption mode command to disable role preemption.

Role preemption is disabled by default.

Examples

# Enable the role preemption mode.

<Sysname> system-view [Sysname] smart-link group 1 [Sysname-smlk-group1] preemption mode role

protected-vlan

Syntax

protected-vlan reference-instance instance-id-list

undo protected-vlan [ reference-instance instance-id-list ]

View

Smart link group view

Default level

2: System level

Parameters

reference-instance instance-id-list: Specifies the MSTIs to be referenced in the form of instance-id-list =

{ instance-id [ to instance-id ] }&<1-10>, where the range of the instance-id argument is as specified in the command configuring MSTIs and &<1-10> indicates that you can provide up to ten MSTIs or MSTI lists.

Description

Use the protected-vlan command to configure protected VLANs for a smart link group by referencing MSTIs. You can use the display stp region-configuration command to view the VLANs mapped to the referenced MSTIs.

Use the undo protected-vlan command to remove the specified protected VLANs from a smart link group by referencing the specified MSTIs. If no MSTI is specified, all the protected VLANs of the smart link group are removed.

By default, no protected VLAN is configured for a smart link group.

NOTE:

• Before assigning ports to a smart link group, configure protected VLANs for the smart link group.

• You can remove all protected VLANs from a smart link

roup when the group is empty but not after a

member port is assigned to it.

• Removing a smart link group also removes its protected VLAN configuration.

• If the VLAN(s) mapped to a referenced MSTI changes, the protected VLAN(s) also change.

• The VLANs that the member ports of a smart link group belong to must be configured as the protected

VLANs of the smart link group.

Related commands: smart-link group; display stp region-configuration (Layer 2—LAN Switching Command Reference).

Examples

# Configure the VLANs mapped to MSTIs 1 through 10 and MSTI 12 as the protected VLANs of smart link group 1.

<Sysname> system-view [Sysname] smart-link group 1 [Sysname-smlk-group1] protected-vlan reference-instance 1 to 10 12

Parameters

control-vlan vlan-id-list: Specifies the control VLANs used for receiving flush messages. The vlan-id-list is

expressed in the form of vlan-id-list = { vlan-id [ to vlan-id ] }&<1-10>, where the vlan-id argument represents the ID of a control VLAN which ranges from 1 to 4094. &<1-10> indicates that you can provide up to ten VLAN IDs or VLAN ID lists.

Description

Use the smart-link flush enable command to configure a receive control VLAN (a VLAN for receiving flush messages).

Use the undo smart-link flush enable command to disable flush message processing.

By default, flush messages are not processed.

If no VLAN is specified, VLAN 1 applies.

This command cannot be used on member port of an aggregation group.

Related commands: flush enable.
