头一次对新的4506配置,遇到了一个奇怪的现象,终端设备,比如我自己的笔记本与4506中的48口的电口相连,配置好IP后,正常学到ARP,PING之类的都正常。+ ~# R5 M) ^* z: Z: m
问题来了: U% [7 v! q4 E: i Z1 c
笔记本只要重新插拔网线(不小心碰断也好,最终的结果都是重新插拔了网线)
" q6 ^6 \# s1 h7 Y8 D交换机中的对应的笔记本原本的IP的表项还在,但是匹配不上(MAC地址和IP都对应着笔记本)
, s* O, C$ o' n) c+ e3 I2 E笔记本就会探测到自己地址有冲突(静态指定,插拔后没变过)0 I Z7 W4 L1 |* X) ?
然后WINDOWS给自己分配了1699 W% R# h4 ^: z+ w/ c

然后交换机就只认169的IP,ARP表中就出现了2个笔记本MAC地址的表项(1个169的,1个原本指定的IP的)5 z1 o: W" ^0 M* z( e8 U1 F* ?

目前解决方法有2个,插拔后 手动清ARP表,或者再重新插拔次才能正常。' B4 g$ _8 j3 x% G" x# V
想知道这有什么更好的解决办法,或者是不是版本的BUG,万分感谢。- m& I; L7 z" \& m
