Configuration Example

Configuration Example

This section describes the service networking and planning information about a LAG configured to provide protection for Ethernet links.

Networking Diagram

As shown in Figure 5-2, a load non-sharing LAG solution will apply. In this solution, two GE links are bundled as a LAG to provide 1+1 link backup and to ensure reliable transmission of the service between the PowerCube 500 and Router.

Service Planning

The service planning information contains the information about all the parameters required for configuring the NE data.

Creating a LAG

LAG No.

LAG Name

LAG1

LAG Type

Static (default value)

  • Static: In static link aggregation, a user creates a LAG and Link Aggregation Control Protocol (LACP) is started if a member port is added or deleted.
  • Manual: In manual link aggregation, a user creates a LAG and LACP is not started if a member port is added or deleted.

The devices at both ends of a LAG must use the same link aggregation mode.

It is recommended that you set this parameter to Static because a static LAG provides higher link reliability than a manual LAG. Set this parameter to Manual when the equipment is interconnected with equipment that does not support LACP. For a manual LAG, it is recommended that you configure IEEE 802.3ah OAM to monitor the link status and enable both ends to perform a LAG switchover once a unidirectional fiber cut is detected.

Link Detection Protocol

Null (default value)

  • Null: No link monitoring protocol is used for a manual LAG.
  • 3ah: IEEE 802.3ah is used as a link monitoring protocol for a manual LAG.

The value 3ah is recommended if the interconnected device supports IEEE 802.3ah. This ensures that services are switched to the same link at both ends.

Revertive

Revertive (default value)

  • Revertive: Services will be switched back to the member link with a higher priority after the link recovers from faults.
  • Non-Revertive: Services will not be switched back to the member link with a higher priority after the link recovers from faults. Services will be switched back only after the member link that is carrying the services fails.

This parameter value must be the same at both ends of a LAG.

This parameter can be set only after Load Sharing is set to Non-Sharing.

Load Sharing

Non-Sharing

  • Sharing: Each member link in a LAG carries traffic. That is, the member links in the LAG share the load. The sharing mode increases Ethernet link bandwidth. When a member in a LAG changes or a link fails, the traffic is re-allocated automatically.
  • Non-Sharing: Only one member link of a LAG carries traffic and the other member link is in standby state. In this case, a link hot backup mechanism is provided. When the active link of a LAG is faulty, the system activates the standby link to transmit service traffic.

It is recommended that you set this parameter to Non-Sharing when a LAG is expected to provide link protection. It is recommended that you set this parameter to Sharing when a LAG is expected to increase link bandwidth.

For a manual LAG, both ends must use the same load sharing mode; otherwise, services will be interrupted.

System Priority

32768 (default value)

The smaller the value, the higher the system priority.

WTR Time (min)

10 (default value)

This parameter can be set only after Revertive is set to Revertive.

Packet Receive Timeout Period

Long period (default value)

This parameter specifies the timeout duration for a port to receive LACP Packets.
  • Short period: The interval at which LACP packets are sent is 1s. The timeout duration of receiving LACP packets is 3s.
  • Long period: The interval at which LACP packets are sent is 30s. The timeout duration of receiving LACP packets is 90s.

Main Board

2-EG6P

Set this parameter according to the plan.

Main Port

1(PORT-1)

Set this parameter according to the plan.

Board

2-EG6P

Set this parameter according to the plan.

Selected Standby Ports

2-EG6P-2(PORT-2)

Set this parameter according to the plan.

Procedure
