升级IOS后，Router的端口增加了，怎么回事？

biner

好不容易找到一台C831练手，刚拿到就升级了一下IOS，原来的版本太低了，升级后发现一些问题请教一下大家。
原IOS版本：c831-k9o3y6-mz.123-2.XC2.bin
新IOS版本：c831-k9o3sy6-mz.124-12c.bin

问题：
原版本软件show interface显示：
CISCO C831 (MPC857DSL) processor (revision 0x500) with 58983K/6553K bytes of mem
ory.
Processor board ID FHK092021FZ (2559971634), with hardware revision 0000
CPU rev number 7
Bridging software.
2 Ethernet/IEEE 802.3 interface(s)
4 FastEthernet/IEEE 802.3 interface(s)
128K bytes of non-volatile configuration memory.
12288K bytes of processor board System flash (Read/Write)
2048K bytes of processor board Web flash (Read/Write)

Configuration register is 0x2102

怎么会多出一个Ethernet interface？

实际是多少个以太口

加上管理端口和WAN口，一共6个端口。

实际可以使用的只有4个。

eth0-eth4

呵呵，这就对了吧。2个10M的以太口。

呵呵，这就对了吧。2个10M的以太口。

但是路由器上只有1个10M的接口 1个管理口 4个100M的以太网口。

难道那个管理口也可以配置成10M接口，高级点的IOS里面的东西真多。
