WLC5520分布式端口(数据口)使用1G模块!
思科WLC5520有两个分布式端口。
在 10G 模式和 1G 模式之间切换
•如果在端口 1 上未安装任何内容,则默认情况下主板配置为 10G 模式。因此,要切换到 1G 模式,则必须在端口 1上安装 SFP 模块,并需要重启系统。
•反之,如果安装了SFP模块,并且用户希望切换到 4 x 10G 模式,则必须在端口 1 中安装 SFP+ 模块,并且重启 WLC。
•因此,在 10G 模式和 1G 模式之间,无法进行 SFP 和 SFP+ 的在线插拔 (OIR)。
•但是在 10G 模式之间以及 1G 模式之间,可以进行 OIR。
英文的文档看起来好理解些:
Switching Between 10 G and 1 G
-
If there is nothing installed in port 1, the board will be configured for 10 G mode by default. Therefore, to switch to 1 G mode, an SFP module must be installed in port 1 and the system needs to be rebooted.
-
Conversely, if an SFP module is installed and the user wants to switch to 4 x 10 G mode, then an SFP+ module must be installed in port 1 and the WLC rebooted.
-
Thus, Online Insertion and Removal (OIR) of SFP and SFP+ between 10 G and 1 G is not possible.
-
OIR of 10 G to 10 G and 1 G and 1 G is possible.
Note:It is recommended to have all ports as either 10 G or 1 G. In case they are different, port 1 SFP determines the mode of operation and functionality on the other SFPs may not work.
Port1是来决定端口运作为1G还是10G的模式下的。
SFP Support
Network ports for 5520 WLC support the following Cisco SFP/SFP+ modules:
-
GLC-T
-
GLC-TE
-

-
SFP-10G-LR
-
SFP-10G-LRM
-
SFP-H10GB-CU1M

SFP-10G-SR-S
-
SFP-10G-LR-S
Note:*Needs GLC-T on Port 1.
这里已经提到了这些打“*”的模块,需要再Port1安装GLC-T的模块。所以在实施的时候,很容易遇到这样的情况,如果Port在使用这些模块的时候,如果接口1没有安装GLC-T的模块,接口起不来,且10G的等一直琥珀色亮着。所以,注意!!!WLC5520默认的两个10G的数据口如果使用千兆模块时,Port 1必须为GLC-T模块(或许GLC-TE也可以,但最好还是根据思科建议来)。
