请看我的设置：
2600(config)#int s0/0
2600(config-if)#ip address 192.168.1.1 255.255.255.0
2600(config-if)#no shut
2600(config-if)#^Z
2600#
00:03:17: %SYS-5-CONFIG_I: Configured from console by console
00:03:19: %LINK-3-UPDOWN: Interface Serial0/0, changed state to down
00:03:44: %LINK-3-UPDOWN: Interface Serial0/0, changed state to up
00:03:45: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0, changed state to up
00:04:07: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0, changed state to down
请问，为什么先是changed state to up，然后马上有changed state to down了呢？

同问～～求解答！！！
