CISCO IOS的命名规则2010年01月07日 星期四 17:39IOS的命名规则是这样的,例如:
IOS有主版本号:11.0、11.1、11.2、11.3、12.0、12.1、12.2、12.3、12.4等,这些主版本号相当于windows的版本有win98、win2000、winxp、win2003。
当Cisco发布了某个主版本号的IOS以后,它会对它进行维护(仅修正bug,不添加新功能),每维护一次,维护版本号加1。例如c2500-is-l.121-27.bin中的“121-27”代表主版本号为12.1,维护了27次。
当一个主版本号的IOS发布一段时候后,Cisco会放出基于该主版本的下一版本IOS的测试版,IOS名字后面会加上“T”字,例如:c2500-is-l.122-15.T16.bin,当正式发布的时候,它将成为12.3版本。
