Huawei performed the following operations to address the problem:
1. Checked the packet transmission frequencies at the two ends.
They were different.
2. Checked configurations at the two ends.
The configurations were default configurations. Devices from different vendors process protocols differently.
According to IEEE 802.3ad, the timeout field in an LACP packet can control the LACP packet transmission frequency of the remote end as follows:
1. If the short timeout is configured at the local end, the remote end transmits one LACP packet every second.2. If the long timeout is configured at the local end, the remote end transmits one LACP packet every 30 seconds.
