當配置多個vlan時候，在鍵入exit或apply時候經(jīng)常會出現(xiàn)下面的出錯信息，使得無法創(chuàng)建新的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
解決辦法:出現(xiàn)錯誤時候，鍵入abort先退到特權模式，然后打入erase flash，點確定完，再進入vlan database配置vlan即可。
