LACP Link Aggregation Interworking or Replacement Guidance
Introduction to LACP Link Aggregation
The link aggregation modes and configurations of devices from different vendors are different. How is link aggregation implemented between devices from different vendors?
The Link Aggregation Control Protocol (LACP) is a public protocol and LACP Data Units (LACPDUs) are the same, so Huawei devices can interwork with or replace third-party devices that support LACP. The following describes interworking of LACP link aggregation between Huawei device and Cisco, H3C, and Juniper devices, as described in Table 3-1.
Table 3-1 Interworking of LACP link aggregation
Vendor |
LACP Link Aggregation Mode and Command |
|---|---|
Huawei |
Static LACP mode mode lacp-static |
Cisco |
Static LACP mode channel-group number mode active channel-group number mode passive |
H3C |
Dynamic LACP mode link-aggregation mode dynamic |
Juniper |
LACP mode [edit interfaces interface-name aggregated-ether-options]
lacp {
active;
}
[edit interfaces interface-name aggregated-ether-options]
lacp {
passive;
}
|
Typical Networking
Before connecting or replacing the devices, ensure that the link aggregation modes at both ends are the same and the numbers of physical member interfaces at both ends are the same. The following provides examples for using the Huawei device in LACP mode to interwork with or replace devices from Cisco, H3C, or Juniper.
Note: The following interface names are just used as examples and may be different from actual interface names on devices.
Case 1: A Huawei device interworks with or replace a Cisco device
- NetworkingFigure 3-1 A Huawei device interworks with or replace a Cisco device
- Procedure
Create a link aggregation group (LAG), configure an LACP mode, and add interfaces to an Eth-Trunk.
