When the hash algorithm is set to random, symmetric load balancing does not take effect.

NetEngine 8000 F

NetEngine 8000 F2A/NetEngine 8000 F1A

Symmetric load balancing does not support CE dual-homing scenarios.

NetEngine 8000 F

NetEngine 8000 F2A/NetEngine 8000 F1A

Symmetric load balancing does not support E-Trunk scenarios.

NetEngine 8000 F

NetEngine 8000 F2A/NetEngine 8000 F1A

Symmetric load balancing does not support trunk localization scenarios.

NetEngine 8000 F

NetEngine 8000 F2A/NetEngine 8000 F1A

Symmetric load balancing does not support multi-level load balancing scenarios.

NetEngine 8000 F

NetEngine 8000 F2A/NetEngine 8000 F1A

Symmetric load balancing does not support multicast scenarios.

NetEngine 8000 F

NetEngine 8000 F2A/NetEngine 8000 F1A

Symmetric load balancing cannot work with MAC address- or label-based load balancing.

You are advised to properly plan services.

NetEngine 8000 F

NetEngine 8000 F2A/NetEngine 8000 F1A

Symmetric load balancing supports data traffic packets instead of protocol packets between two devices.

NetEngine 8000 F

NetEngine 8000 F2A/NetEngine 8000 F1A

For symmetric load balancing:

1. If the device connects to a non-Huawei device, upstream and downstream traffic may not be hashed to the same link due to different load balancing algorithms.

2. If the device connects to a Huawei device that does not support symmetric load balancing, upstream and downstream traffic may not be hashed to the same link.

NetEngine 8000 F

NetEngine 8000 F2A/NetEngine 8000 F1A

Fragmented and non-fragmented packets of the same flow are transmitted through different paths. The first fragment and subsequent fragments are transmitted through the same path.
