3.在升级前检查Firmware version

Router# show platform
Chassis type: MCP4RU
Slot      Type                State                 Insert time (ago) 
--------- ------------------- --------------------- -----------------

 0/3      SPA-2X1GE-V2        ok                    00:00:37

R0        09081701            15.0(1r)S                           
F0        07051650            15.0(1r)S 

4.执行升级的操作

最后的选择，可以选择all，或者对应的模块，这里是all的方式，因为上面可以看到所有的firmware都需要升级。

5.重启和检查

重启并等待设备启动完成后，还是通过show plat来检查firmware升级情况。

Router# reload
Proceed with reload? [confirm]
<Reload bootup output removed for brevity. In this example, it is assumed that autoboot is enabled on the router.>
Press RETURN to get started!
Router> enable
