c2960x-universalk9-mz.150-2.EX5
c2960x-universalk9-mz.152-4.E8.bin
以上这两个版本有何区别,2960X升级后配置是不是会有变化?

多了下面的特性:
IPv6 dACL: Supports IPv6 downloadable ACLs (dACL) for authentication and authorization into the network for end-point clients or devices. Cisco Identity Services Engine (ISE) pushed the dACL to the switch or controller, which in turn attaches it with the end-point.
Loop Detection: A new method to detect network loops in the absence of Spanning Tree Protocol (STP) is introduced. When an edge switch is connected to an unmanaged switch that does not understand STP or it is part of a network topology where STP is not usable, the loop-detect sub-system sends a frame to the interface, at configured intervals, and detects loops.
SFTP: The device supports SSH File Transfer Protocol (SFTP). The SFTP client functionality is provided as part of the SSH component and is always enabled on the corresponding device. Therefore, any SFTP server user with the appropriate permission can copy files to and from the device.
Private VLAN (PVLAN) support for Multicast Traffic: Multicast traffic is routed or bridged across PVLAN boundaries and within a single community VLAN. Multicast traffic is not forwarded between ports in the same isolated VLAN or between ports in different secondary VLANs.
其他的命令是一样的哦

楼主可以参考一下
了解Cisco IOS命名惯例
https://www.cisco.com/c/zh_cn/support/docs/ios-nx-os-software/ios-software-release-1513t/200095-Understanding-Cisco-IOS-Naming-Conventio.html
2960X各个IOS的release notes可以在下面的页面查到。

PS:c2960x-universalk9-mz.150-2.EX5没有.bin后缀,所以这个是IOS文件所在的文件夹。使用dir flash: c2960x-universalk9-mz.150-2.EX5来查看该文件夹内具体的IOS文件。

如果怕配置在升级后有变化的话,最好在升级之前先做个备份。

升级前备份之前能正常运行的IOS文件和文件名
因为现在假货泛滥,不管是思科思科,还是华为华三,自己多注意。
如果是假货机器,换完IOS就会报非思科授权告警,且端口之间无法交换数据。
祝你升级成功

IOS-XE系统变化挺大的,要注意。但可双命令共存。
