Huawei quidway s7700 - Optional) Limiting the Number of Active Interfaces

interface information to perform the Exclusive-OR calculation, and then selects the outgoing
interface from the Eth-Trunk table according to the calculation result.
l Enhanced load balancing: The S7700 selects interfaces to forward packets according to the
load balancing mode defined for different packets by the enhanced load balancing profile.
Member interfaces of an Eth-Trunk perform per-flow load balancing. The local end and the
remote end can use different load balancing modes, and the load balancing mode on one end
does not affect load balancing on the other end.

2.4.5 (Optional) Limiting the Number of Active Interfaces
Context
Do as follows on the S7700 where you need to limit the number of active interfaces.
Procedure
l Setting the upper threshold of the number of active interfaces
1. Run:
system-view
The system view is displayed.
2. Run:
interface eth-trunk trunk-id
The Eth-Trunk view is displayed.
3. Run:
max active-linknumber link-number
The upper threshold of the number of active interfaces is set.
By default, the upper threshold of the number of active interfaces is 8.
In static LACP mode, you can limit the maximum number (M) of active interfaces in the
Eth-Trunk by setting the upper threshold. The other member interfaces function as backup.
If the upper threshold is not set, up to eight interfaces in the Eth-Trunk can be active.
NOTE
l The upper threshold of the number of active interfaces should not be smaller the lower threshold
for the number of active interfaces.
l The upper threshold of the number of active interfaces of the local S7700 and that of the remote
S7700 can be different. If the upper thresholds at two ends are different, the smaller one is used.
l Setting the lower threshold of the number of active interfaces
1. Run:
system-view
The system view is displayed.
2. Run:
interface eth-trunk trunk-id
