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。\r\n原IOS版本：c831-k9o3y6-mz.123-2.XC2.bin\r\n新IOS版本：c831-k9o3sy6-mz.124-12c.bin\r\n\r\n问题：\r\n原版本软件show interface显示：\r\nCISCO C831 (MPC857DSL) processor (revision 0x500) with 58983K/6553K bytes of mem\r\nory.\r\nProcessor board ID FHK092021FZ (2559971634), with hardware revision 0000\r\nCPU rev number 7\r\nBridging software.\r\n2 Ethernet/IEEE 802.3 interface(s)\r\n4 FastEthernet/IEEE 802.3 interface(s)\r\n128K bytes of non-volatile configuration memory.\r\n12288K bytes of processor board System flash (Read/Write)\r\n2048K bytes of processor board Web flash (Read/Write)\r\n\r\nConfiguration register is 0x2102\r\n\r\n新版本软件show interface显示：\r\nCisco C831 (MPC857DSL) processor (revision 0x500) with 58983K/6553K bytes of mem\r\nory.\r\nProcessor board ID FHK092021FZ, with hardware revision 0000\r\nCPU rev number 7\r\n3 Ethernet interfaces\r\n4 FastEthernet interfaces\r\n128K bytes of NVRAM.\r\n12288K bytes of processor board System flash (Read/Write)\r\n2048K bytes of processor board Web flash (Read/Write)\r\n\r\nConfiguration register is 0x2102\r\n\r\n怎么会多出一个Ethernet interface？
