当配置多个vlan时候，在鍵入exit或apply时候经常会出现下面的出错信息，使得无法创建新的vlan SW1(vlan)#exit % not enough space on flash to store vlan database. trying squeeze...First create squeeze log by erasing the entire device
% error squeezing flash - (Missing Ｏr corrupted log) Error on database apply 40: NV storage failure Use \'abort\' command to exit SW1(vlan)#
sw1#erase flash: Erasing the flash filesystem will remove all files! Continue? [confirm] Erasing device... eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee ...erased Erase of flash: complete 解决办法:出现错误时候，鍵入abort先退到特权模式，然后打入erase flash，点确定完，再进入vlan database配置vlan即可。
