什么是Cisco ACI命令，相当于Cisco IOS的“显示版本”？

Question

基于这个链接，Cisco ACI实际上是基于Cisco Nexus 9000系列的。

它的硬件是基于思科Nexus 9000系列交换机。

但是当Cisco或IOS确实有show version命令时，为什么Cisco没有类似的命令呢？

我想知道更多关于这个设备，如型号，软件版本等。

思科ACI的正确命令是什么？可能是相当于思科IOS show version的东西？

Answer 1

每个ACI交换机都可以通过show version显示版本输出。

在APIC上执行的show version命令将显示fabric元素的软件版本：

APIC-1# show version

要从APIC远程在叶子/脊柱上运行命令，输入fabric NODE_ID <command>：

APIC-1# fabric 101 show version

APIC-1# fabric 104-106,202 show version
