为了提高可用的网络带宽和容错能力，可以聚合为 NSX Advanced Load Balancer SE 分配的多个虚拟功能 (VF) 网络接口以形成端口通道或绑定接口。
必备条件
交换机上不需要特定于端口通道的配置。
为了获得预期优势，端口通道成员接口应与不同的物理功能 (Physical Function, PF) 设备或 pNIC 相关联。
CSP 配置
应该在所使用的 CSP pNIC 上启用 SRIOV。以下 CSP 命令可用于实现此目的。
avinet-1(config)# pnic enp7s0f0 sr-iov numvfs 32 switchmode vep
配置
可以使用 NSX Advanced Load Balancer SE 元数据 (yml) 文件配置要绑定在一起以形成端口通道（绑定）的成员（辅助）接口，如下所示：
avi.bond-ifs.SE: '1,2'
上述配置指示 SE 绑定接口 1 和 2 以形成端口通道。
如果需要多个端口通道，则应指定不同端口通道的成员接口索引，索引之间用空格隔开，如下所示：
avi.bond-ifs.SE: '1,2 3,4'
上述配置可让 SE 创建两个端口通道 - 一个具有接口 1 和 2，另一个具有接口 3 和 4。
在 SE 启动后，NSX Advanced Load Balancer UI 中的编辑服务引擎窗口将显示有关绑定接口和辅助接口的信息。
运行 CLI 命令 show serviceengine <SE_IP_Address> interface 以查看接口配置。
