AUX口如果没有在LAG的情况下,是可以用做LAN口的!默认它是用来和主端口做LAG的。

Cisco Aironet 1850, 2800, and 3800 Series APs' second Ethernet port, also called the AUX port如下图中的④, is used as a link aggregation (LAG) port, by default. It is possible to use this LAG port as a LAN port when LAG is disabled.

When the AUX port is configured as a LAN port, you can either use the AP group setting to configure the LAN port for a group of APs, or use the LAN override functionality to configure the LAN port for each AP separately. This Cisco Wave 2 AP AUX port to LAN port conversion feature is supported only in the following APs:

AUX口碑配置为LAN端口的时候,你可以用AP Group来为一组AP配置LAN端口,也可以使用LAN Override功能为每个AP单独配置LAN端口。

如下的AP型号,是可以支持AUX端口用做LAN端口特性的Wave2 AP

AP1852E、AP1852I、AP2802E、AP2802I、AP3802E、AP3802I、AP3802P

 

Note:

After global AP LAG is enabled, the CAPWAP connection with the AP is deleted; that is, the connection is deleted from the database in the controller. This results in AP disjoining and then rejoining the controller. Starting in Release 8.9, the change in functionality is that the connection is explicitly deleted from the database in the controller.

 

After global AP LAG is disabled, for the APs that do not have LAG enabled, their connection is deleted from the database in the controller. This results in APs to disjoin and rejoin the controller.

 

After global AP LAG is disabled, the APs that have LAG enabled are rebooted. This functionality remains unchanged.

 

关于配置

1、默认情况下,AP应该是在LAG模式,检查AP的LAG状态可以通过如下的命令。

 

(WLC)> show ap config general <ap-name>
  LAP# show configuration

 

2、如何关闭LAG模式?

 

(WLC)> config ap lag-mode support disable <ap-name>

 

3、创建Remote-LAN(RLAN)并开启它:

 

(WLC)> config remote-lan create <rlan-id> <rlan-name>
(WLC)> config remote-lan enable <rlan-id>

 

4、创建AP Group,并将RLAN和AP加入到对应的AP Group:

 

(WLC)> config wlan apgroup add <apgroup-name> <description>
(WLC)> config wlan apgroup interface-mapping add <apgroup-name> <rlan-id> <interface-name>
(WLC)> config wlan apgroup <apgroup-name> <ap-name>

 

注意:执行完如上命令之后,AP将重启!

AP重启之后,通过输入此命令,将RLAN分配给AP组中的LAN端口(LAN 1),对于AP1850AP2800AP3800也只能使用LAN 1.

 

(WLC)> config wlan apgroup port lan 1 <apgroup-name> remote-lan <rlan-id>

 

5通过输入以下命令,为AP组中的一组AP或单个AP启用LAN端口(LAN 1

针对AP

 

(WLC)> config wlan apgroup port lan 1 <apgroup-name> enable

 

 

针对单个AP

 

(WLC)> config ap lan over-ride enable <ap-name>
(WLC)> config ap lan port-id 1 enable

 

如此可以连接终端到AUX口!

 

如果要重新开启LAG的话,请参考如下操作:

Step 1

Disable the LAN port (LAN 1) in the AP group by entering this command:

config wlan apgroup port lan1 apgroup-name disable

Step 2

Disable the RLAN on the LAN port (LAN 1) in the AP group by entering this command:

config wlan apgroup port lan1 apgroup-name remote-lan none

Step 3

If LAN is enabled for an individual AP, disable the LAN override for the AP by entering this command:

config ap lan over-ride disable ap-name

Step 4

Enable LAG mode on the AP by entering this command:

config ap lag-mode support enable ap-name
