CIsco 3850 IOS 升级和license的问题

我这边有两台3850-24T-E的机器做堆叠,安装了ipservices的license,IOS的版本比较低,打算升级,但是我发现有个问题,在flash里没有发现XXX.lic文件,请问各位大神,如果我升级了IOS那么需要重新安装license吗?因为我知道如果要向Cisco申请license需要SN和PAK文件,但是那个PAK早就找不到了,另外,我没有在3850里发现config.text文件,那么升级前如何备份?

这个应该是image-base的license吧?
The three feature sets available with all Cisco Catalyst 3850 Series Switches are:
● LAN Base: Enterprise access Layer 2 switching features
● IP Base: Enterprise access Layer 3 switching features
● IP Services: Advanced enterprise Layer 3 switching (IPv4 and IPv6) features
升级不需要重新安装license,升级之前可以保存运行的配置到flash,你的flash里面应该是startup config吧。
没有也可以copy run start 然后到处到tftp server备份吧。

license 应该是ipservices:
#show license right-to-use
Slot# License name Type Count Period left
----------------------------------------------------------
1 ipservices permanent N/A Lifetime
License Level on Reboot: ipservices
Slot# License name Type Count Period left
----------------------------------------------------------
2 ipservices permanent N/A Lifetime
License Level on Reboot: ipservice
系统配置信息是不是在nvram_config这个文件里呢?

默认的启动配置文件通常存储在NVRAM中。
你可以通过如下命令查看:
Device# show startup-config
Displays the contents of the startup configuration file. (Command alias for the more nvram:startup-config command.)
On all platforms except the Class A Flash file system platforms, the default startup-config file usually is stored in NVRAM. On the Class A Flash file system platforms, the CONFIG_FILE environment variable points to the default startup-config file. The CONFIG_FILE variable defaults to NVRAM.
nvram_config和startup-config对比一下看看,就知道是不是了

升级IOS不需要序列号,但你升级完成后,需要设置这个升级后IOS为启动的IOS。

如果有额外购买的license的话,升级IOS需要考虑license的事吗?例如升级IOS后license就没了或者其他情况。我这目前有台ASA 5520有这个情况,所以想咨询下:lol

例如3850要参与SD-Access网络,这个应该就就需要购买license了。但是一般升级都不会导致license丢失的,除非出现了故障。

不好意思,没注意你说的是ASA5520,ASA升级也类似,不过需要注意一下一些升级的注意事项或升级路径(如是否需要有中间版本)是否有所要求。
具体可以查看思科的官方文档,例如如下两个,你可根据需求找一下对应文档完成:
