网络工程 - “lacp 端口优先级”在 Cisco Catalyst 3750 系列上不起作用吗？ - 吾爱随笔录

我有一个 CiscoWS-C3750G-12S交换机，分别与端口Gi1/0/1和Gi1/0/11CiscoWS-C3750G-24TS端口物理连接。端口具有不同的 LACP 端口优先级：Gi1/0/1Gi1/0/27

WS-C3750G-12S#sh lacp internal 
Flags:  S - Device is requesting Slow LACPDUs 
        F - Device is requesting Fast LACPDUs
        A - Device is in Active mode       P - Device is in Passive mode

如上所示，端口具有不同的 LACP 优先级，但仍处于捆绑状态。同样可以看到sh etherchannel 1 summary：

WS-C3750G-12S#sh etherchannel 1 summary 
Flags:  D - down        P - bundled in port-channel
        I - stand-alone s - suspended
        H - Hot-standby (LACP only)
        R - Layer3      S - Layer2
        U - in use      f - failed to allocate aggregator

        M - not in use, minimum links not met
        u - unsuitable for bundling
        w - waiting to be aggregated
        d - default port

请问lacp port-priority在Cisco Catalyst 3750系列不能正常工作？还是我做错了什么？
