S7606如何对外提供不同mac的三层接口

S76系列三层route接口或vlan-interface接口mac地址一致，此现象正常，如下：

[A-2F_Dis_10512-GigabitEthernet1/3/0/17]disp interface g1/3/0/17

GigabitEthernet1/3/0/17

Current state: UP

有些局点需我司提供不同mac的三层接口，S76系列无法通过mac-address修改接口的mac地址，需另行想办法解决。

路由子接口和路由口mac不一致，可一个接口改route口，另一个接口改子接口，具体如下：

[XXZX-1F-S10510-CR-1-1-GigabitEthernet2/2/0/37.100]dis int g 2/2/0/37

[XXZX-1F-S10510-CR-1-1-GigabitEthernet2/2/0/37.100]dis int g 2/2/0/38.100

注： 路由口，发送的报文不会携带vlan tag； 路由子接口发送的报文会携带tag，tag为子接口的编号，例如g 2/2/0/38.100，携带的tag就是100。
