Do member interfaces of a link aggregation group require contiguous interface numbers

0

For S series switches (except the S1700), the member interface numbers of a link aggregation group are not necessarily contiguous. The configuration command determines whether member interface numbers are contiguous:
1. If you run the trunkport command to configure link aggregation, you must specify contiguous interface numbers.
2. If you run the interface eth-trunk command to create a link aggregation group, and then add member interfaces to the group in the interface view, the member interfaces can have discontiguous numbers.

How many member interfaces does an aggregation group of the switch support
An aggregation group of the switch supports a maximum of eight member interfaces. NOTE: An aggregation group of the S2700SI supports a maximum of four member interfaces.

Configure Eth-Trunk on the S1700-FR or S1700-GFR switch
Configure an Eth-Trunk on an S1700-FR or S1700-GFR switch as follows: 1. Add a trunk. a. Choose Interface Management > Eth-Trunk. b. Click New to create a trunk group. c. On the page displayed, configure trunk parameters and add member interfaces to the trunk group. d. Click Apply. 2. Set trunk properties. a. Choose Interface Management > Eth-Trunk. b. Click the editing icon on the right of the trunk to be configured. c. Configure trunk parameters. d. Click Apply.

How to check member interfaces in a port group
You can run the display port-group [ all | port-group-name ] command to check member interfaces in a permanent port group. The port group function allows you to configure interfaces in a batch. However, the device does not support query or saving of the port group configuration. You can run the display this command in the interface view of a member interface to check the configuration that takes effect on the interface. # Check member interfaces in all permanent port groups. display port-group all Portgroup: 1 GigabitEthernet0/0/1 GigabitEthernet0/0/2 GigabitEthernet0/0/3 Portgroup: 2 GigabitEthernet0/0/4 GigabitEthernet0/0/5 GigabitEthernet0/0/6

Can a converted interface be added to an Eth-Trunk
Converted interfaces can be added to an Eth-Trunk. The configuration method is the same as that for adding a physical interface to an Eth-Trunk. # Add converted interface 40GE1/0/1:1 to Eth-Trunk2. system-view [~HUAWEI] interface eth-trunk 2 [*HUAWEI-Eth-Trunk2] trunkport 40ge 1/0/1:1 [*HUAWEI-Eth-Trunk2] commit

What is the difference between the link aggregation group in LACP mode and in manually configured link aggregation group in terms of forwarding performance
For S series switches (except the S1700), there is no difference between an LACP aggregation group and a manually configured link aggregation group in terms of forwarding performance.
