升级 Arista 的可扩展操作系统 (EOS) 是一个简单的过程。简而言之,将软件镜像放到交换机上,配置交换机以查看新镜像,然后重启交换机。首先,让我们使用show version 命令查看 7280R-48C6 交换机上EOS 的当前版本:

Arista#sho ver
Arista DCS-7280SR-48C6-M-F
Hardware version:    21.05
Serial number:       SSJ17290598
System MAC address:  2899.3abe.9f92

Software image version: 4.19.5M
Architecture:           i386
Internal build version: 4.19.5M-7506183.4195M
Internal build ID:      ef83948c-6c45-4097-9d8b-a78a4722d49a

Uptime:                 3 minutes
Total memory:           32463792 kB
Free memory:            30178840 kB

从输出结果可以看出,交换机运行的是 EOS 4.19.5M 版本。

备注

再次查看第一行输出中的型号:DCS-7280SR-48C6-M-F。-F "表示该交换机出厂时配备的是前后风扇。如果型号后面加上"-R",风扇就会从后向前。酷吧?我想是的,不过,像这样的小东西让我很兴奋。-M "表示该交换机具有扩展内存(32 GB)。SR "表示这是一款基于小型可插拔(SFP)的 (S) 交换机,具有高级路由 (R) 功能。48C6 "表示有 48 个前面板 SFP 接口和 6 个 100 Gb (C) 接口。

如果我们想在不属于我们的地方再探个究竟(谁不想呢?),我们可以使用show version detail 命令,它会向我们提供一页又一页的进程名称及其必要的版本:
