我有两个思科3850交换机(3850-1,3850-2).我有VLAN 1,2,3,4,5安装(192.168.1.0 - 192.168.5.0)，使用从3850到1构建的DHCP。

3850-1是192.168.1.3 3850-2是192.168.1.4

我在两个人之间设置了一个以太通道。目前，我已经将它们设置为允许所有VLAN(稍后将进行限制)。

每个VLAN都配置了HSRP，以便VIP作为每个VLAN子网的默认网关保持活动状态。

我有一个新的思科1852e WAP (MObility快速模式)。是192.168.1.5的流动快递经理。

如果我将一个设备(例如iPhone)连接到为VLAN3设置的SSID (Customer)，它的工作效果很好。该设备的IP地址为192.168.3.51，D/G 192.168.3.1。我可以平每一个IP，除了一个(我的3850-1交换机，ip 192.168.1.3).

如果我将设备连接到SSID员工，安装VLAN 2，则设备的IP地址为192.168.2.54d/g 192.168.2.1。除了192.168.1.3 (3850-1)，我什么都可以。

THe疯狂的东西: 192.168.1.3 (3850-1)可以对任一设备的给定IP进行平分，192.168.1.4 (3850-2)也可以。如果我将它们都放入SSH中，它们都可以在SSID/Subnet/VLAN上切换设备。

但这两种设备都不能平192.168.1.3 (3850-1)。

我想知道我的以太频道设置是否错了，怎么了？

快把我逼疯了。我不是这方面的专家。我们就把这个放那儿吧。到目前为止，我还不知道为什么每个交换机都可以在任何SSID上成功地平分任何设备，但是设备不能只切换192.168.1.3 (3850-1)。

这是我3850-1的待机信息：

代码语言：javascript
运行

3850-1#show standby br
                     P indicates configured to preempt.

Vl4         40   100 P Standby 192.168.4.3     local           192.168.4.1

这是3850-2号的：

Vl4         40   100 P Active  local           192.168.4.2     192.168.4.1

这是我3850-1的vlan集群信息：

代码语言：javascript
运行
复制
3850-1#show int trunk

从3850-2开始：

代码语言：javascript
运行
复制
3850-2#show int trunk

Port        Mode             Encapsulation  Status        Native vlan

Gi1/0/23    on               802.1q         trunking      1
Gi1/0/24    on               802.1q         trunking      1

Port        Vlans allowed on trunk
Gi1/0/11    1-4094
Gi1/0/23    1-4094
Gi1/0/24    1-4094

Port        Vlans allowed and active in management domain
Gi1/0/11    1-5,13
Gi1/0/23    1-5,13
Gi1/0/24    1-5,13

Port        Vlans in spanning tree forwarding state and not pruned
Gi1/0/11    1-5,13
Gi1/0/23    1-5,13
Gi1/0/24    1

我的1852e在3850-2G1/0/11上，根据思科的MObility快递文档，它被设置为一个主干端口，以便于在各种VLAN上使用SSID。

我的以太通道在每个交换机上配置为g1/0/23和g1/0/24。

这是我的心声(3850-1)：

Etherchannel并没有完全建立起来。从PAgP切换到LACP。THis链接提供了帮助。

本质上，我在一端有一个不完整的配置。在每个交换机上通过和重建int PO1，使用LACP而不是PAgP修复它。效果很好。
