当配置多个vlan时候在键入exit或apply时候经常会出现下面出错信息使得无法创建新vlan

　　SW1(vlan)#exit

　　% not enough space on flash to store vlan database. trying s queeze...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
