"lacp端口优先“不适用于Cisco催化剂3750系列吗？

Question

我有一个思科WS-C3750G-12S交换机物理连接端口Gi1/0/1和Gi1/0/11到思科WS-C3750G-24TS端口Gi1/0/1和Gi1/0/27。端口有不同的LACP端口-优先级：

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     

Channel group 1
                            LACP port     Admin     Oper    Port        Port
Port      Flags   State     Priority      Key       Key     Number      State
Gi1/0/1   SA      bndl      1             0x1       0x1     0x102       0x3D  
Gi1/0/11  SA      bndl      2             0x1       0x1     0x10C       0x3D

        F - Device is requesting Fast LACPDUs
        A - Device is in Active mode       P - Device is in Passive mode

Channel group 1
                            LACP port     Admin     Oper    Port        Port
Port      Flags   State     Priority      Key       Key     Number      State
Gi1/0/1   SA      bndl      1             0x1       0x1     0x102       0x3D
Gi1/0/27  SA      bndl      2             0x1       0x1     0x11C       0x3D
WS-C3750G-24TS#

如上文所示，端口有不同的LACP优先级，但仍然捆绑在一起。在sh etherchannel 1 summary中也可以看到：

WS-C3750G-12S#sh etherchannel 1 summary 
Flags:  D - down        P - bundled in port-channel
        I - stand-alone s - suspended

        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

lacp port-priority不工作在思科催化剂3750系列？还是我做错什么了？

Answer 1

我觉得这很正常。我想你可能对这个命令的性质有误解。

这应该会有所帮助，来自思科文档：

当一个lacp信道组中有8个以上端口时，LACP端口优先级接口配置命令确定哪些端口被捆绑，哪些端口处于热待机模式。
