先配置DOT1Q,在接口下sw trunk en dot1q ,sw mode trunk
配置完TRUNK后。将两台设备的TRUNK口,全都SHUTDOWN。然后在配置tunnel,tunnel的类型要选择pagp,一端的tunnel的模式为auto,另一端的模式配置des,配置完成后两端接口再NO SHUT

Creates an 802.1Q tunnel on the port. The port will go down and reinitialize (port flap) when the interface
mode is changed. BPDU filtering is enabled and CDP is disabled on tunnel interfaces.
不同版本配置Configuring Q-in-Q VLAN Tunnels的手册,楼主可以参考一下

貌似 Cisco nexus3548不再支持QinQ(之前好像是支持的),在它的data_sheet页面中没找到相关的描述。
