It can support bonding technology, which combines two 400G ports into one 800G port, increasing bandwidth and redundancy. However, to achieve the effect of reaching 800G after bonding, the following conditions need to be met:<\/span><\/p><p><span style=\"font-size: 14pt;\">1. Use OSFP connectors and NDR cables, which can provide 400 Gb\/s of bandwidth.<\/span><\/p><p><span style=\"font-size: 14pt;\">2. Use switches that support 800G, such as the Cisco Nexus 9800 Series or Cisco Nexus 9232E.<\/span><\/p><p><span style=\"font-size: 14pt;\">3. Configure the correct bonding mode and parameters, such as LACP, load balancing, failover, etc.<\/span><\/p><p><span style=\"font-size: 14pt;\">If you use QSFP connectors or HDR\/EDR cables, then the bandwidth after bonding will be limited, because the maximum bandwidth of QSFP connectors and HDR\/EDR cables are 200 Gb\/s and 100 Gb\/s respectively.
