How to Setup Link-Aggregation to Uplink Ports on Huawei OLT?

Abstract

This topic will guide you how to setup link-aggregation to uplink ports on Huawei OLT ?

 

Function

The link–aggregation command is used to create an Ethernet link aggregation group (LAG) and specify the master port in the group. Ethernet link aggregation means that two or more Ethernet ports of the same type are bound as a logical port. It improves link bandwidth without a hardware upgrade and effectively hardens link reliability using a link backup mechanism.

The undo link–aggregation command is used to delete an Ethernet LAG. After the master port in an Ethernet LAG is deleted, the Ethernet LAG is deleted and the protection and load sharing among ports in the Ethernet LAG are also canceled.

NOTE:

When adding a port to or deleting a port from a link aggregation group, if this port is already connected to the peer device, run the shutdown command for the port or remove the optical fiber to avoid a link loop.

 

Format

link–aggregation frameid/slotid port-list [ frameid/slotid port-list ] mode [ workmode lacp-static ]

undo link–aggregation { frameid/slotid/portid | all }

 

NOTE: If lacp mode is used, the uplinking suit is ZTE or Cisco suit, it must use :

Parameters

Parameter	Description	Value
frameid/slotid	Indicates the subrack ID and slot ID for member ports in an aggregation group. Enter a slash (/) between the subrack and slot IDs. For inter-board link aggregation, if two or more ports on two boards are added into an LAG, you must enter this parameter twice. The frameid/slotid values indicate where the two boards are installed. For intra-board link aggregation, if two or more ports on one board are added into an LAG, you only need to enter this parameter once. The frameid/slotid value indicates where the board is installed.	/
port-list	Indicates the aggregation port list. There is one port or multiple ports in the list. If there are multiple ports in the list, you can use “,” to divide different ports and “-” to connect the successive ports. For example, “0, 2-5, 7”. NOTE: The port with the smallest port ID is the master port. If you specify only one port, you need to run the link-aggregation add-member command to configure slave ports.	Character string type, a string of 1-255 characters.
mode	Indicates packet distribution mode of the aggregation group. To ensure that the peer ports correctly receive the packets carried over member links, and the traffic is evenly loaded by these member links, the device distributes packets in the following mode when performing load sharing: · ingress indicates that the member ports distribute packets based on the source MAC address. · egress-ingress indicates that the member ports distribute packets based on the source MAC address and destination MAC address. This mode is recommended when the device does not support the MPLS feature. · mpls-label indicates that the member ports distribute packets based on the MPLS label. This mode is recommended when the device supports the MPLS feature. · src-dst-ip indicates that the number ports distribute packets based on the source IP address and destination IP address. · ip-enhance indicates that the member ports distribute packets based on the IP address and protocol number.	Enumerated type. Options: ingress, egress-ingress, src-dst-ip, ip-enhance and mpls-label.
workmode lacp-static	Sets the aggregation group of the LACP static aggregation type. If this parameter is not specified, the aggregation group type is manual aggregation. · When the access device is interconnected with one that supports the LACP protocol, it is recommended that you specify this parameter. An LACP static LAG is manually created and the LACP protocol running at the interconnected devices controls link aggregation. (If aggregation type is static aggregation, the LACP protocol packets may be frequently exchanged, causing a system overload, when the access device cascades multiple lower-layer devices for aggregation.) · When the access device is interconnected with one that does not support the LACP protocol, the aggregation type must be set to manual aggregation. Users manually create and control an manual LAG. (If aggregation type is manual aggregation, the transmit device cannot detect a unidirectional fault on a link (for example, a fiber cut in one direction at an Ethernet optical port) or an incorrect physical line connection.)	–
frameid/slotid/portid	Indicates the master port in the aggregation group. Enter a slash (/) between the subrack and slot IDs. When you need to delete an LAG by deleting the master port in the LAG, use this parameter.	/
all	Deletes all LAGs.	–

 

Example

To add ports 0/9/0 and 0/9/1 into a LACP static aggregation group in ingress mode, do as follows:

huawei(config)#link-aggregation 0/9                                                 

{  port-list<S><Length 1-255> }:0-1

{ frameid/slotid<S><Length 3-15>|mode<E><ingress,egress-ingress,mpls-label,src-d

st-ip,ip-enhance}:ingress                  

{ <cr>|workmode<K> }:workmode                                                   

{ lacp-static<K> }:lacp-static                                                  

                                                                                

  Command:                                                                      

          link-aggregation 0/9 0-1 ingress workmode lacp-static  

To add ports 0/9/0 and 0/9/1 into a manual aggregation group in engress-ingress mode, do as follows:

huawei(config)#link-aggregation 0/9                                                 

{ port-list<S><Length 1-255> }:0

{ frameid/slotid<S><Length 3-15>|mode<E><ingress,egress-ingress,mpls-label,src-d

st-ip,ip-enhance}:0/9                     

{ port-list<S><Length 1-255> }:1                                                      

{ mode<E><ingress,egress-ingress,mpls-label,src-dst-ip,ip-enhance> }:egress-ingress                    

{ <cr>|workmode<K> }:

 

  Command:                                                                      

          link-aggregation 0/9 0 0/9 1 egress-ingress

To delete the aggregation group including port 0/9/1, do as follows:

huawei(config)#undo link–aggregation 0/9/1                               

  This operation will clear the configuration of slave port, and may cause service interruption of slave port, are you sure to continue? (y/n)[n]:y
