下载和部署 OVF

知识兔下载链接如上所述,或者去 Cisco 软件下载 页面,搜索 “Nexus 9000v”,登录 Cisco 账号,开始下载,该软件不需要服务合同,可以使用一般账号下载。

VMware Workstation “Open a Virtual Machine”,导入 ova 文件,默认导入到用户主目录下的 vmware 文件夹下。

配置串口

添加串口

知识兔

编辑虚机设置,出现 “设置” 页面如下,点击 “Add…”

img

选择 “串行端口”,点击 “Finish”

img

回到 “设置” 页面,编辑串口属性如下:

Use socket (named pipe),名称没有固定要求,本例使用 /tmp/serial0,连接串口需要使用该名称。

From:Server To:An Application(必须)

编辑 vmx

知识兔

打开虚拟机目录,默认为用户主目录下的 vmware 文件夹下即 ~/vmware,找到 nexus9500v64.10.1.2,用文本编辑器打开 nexus9300v.10.1.2.vmx,将 serial0.fileType = "file" 修改为 serial0.fileType = "pipe"

连接串口

(1)安装 socat:

# for Debian、Ubuntu
sudo apt install socat
# for Redhat、CentOS
yum install socat

socat - Multipurpose relay
socat 是 Unix 下的一个多功能的网络工具,名字来由是 “Socket CAT”。其功能与有瑞士军刀之称的 Netcat 类似,可以看做是 Netcat 的加强版。
Socat 的主要特点就是在两个数据流之间建立通道,且支持众多协议和链接方式。如 IP、TCP、UDP、IPv6、PIPE、EXEC、System、Open、Proxy、Openssl、Socket 等。

(2)开启虚机,出现了启动画面(截图略):

(3)连接串口 serial0:

1
socat -d -d unix-connect:/tmp/serial0 stdio

-d 参数最多可以用 4 个,表示输出的信息级别越多,参看 man socat
unix-connect: 后面跟串口文件的实际路径,比如:$HOME/vmware/serial0
stdio = stdin,客户端只进行标准输入

(4)画面出现大量字符:

(5)按回车键可以看到如下提示:

1
- Abort Power On Auto Provisioning [yes - continue with normal setup, skip - bypass password and basic configuration, no - continue with Power On Auto Provisioning] (yes/skip/no)[no]:

输入 yes 停止 POAP(Cisco NX-OS PowerOn Auto Provisioning)

(6)出现初始化配置界面:

## 配置管理 IP
switch# conf t
Enter configuration commands, one per line. End with CNTL/Z.
switch(config)# interface mgmt0
switch(config-if)# ip address 10.0.2.15/24
# <--- NOTE: can use "ip address dhcp" here instead
switch(config-if)# no shut
switch(config-if)# end
# 此时可以通过 ssh 访问管理口,默认 ssh 服务开启。

# 配置管理口路由
switch(config)#vrf context management
switch(config-vrf)# ip route 0.0.0.0/0 10.0.2.1

## 配置引导镜像 (sysin)
switch# conf t
Enter configuration commands, one per line. End with CNTL/Z.
switch(config)# boot nxos bootflash:nxos.10.1.2.bin
# 或者直接 boot nxos nxos.10.1.2.bin
# <--- Note: use correct imagename from "dir" command output
switch(config)# copy r s
[########################################] 100%
Copy complete.
switch(config)#
# 运行 show boot 命令确认
switch(config)# show boot
show boot
Current Boot Variables:
sup-1
NXOS variable = bootflash:/nxos.10.1.2.bin
Boot POAP Disabled

Boot Variables on next reload:
sup-1
NXOS variable not set
Boot POAP Disabled
switch#

## 添加一个用户(可选)
switch(config)# username sysin password vagrant role network-admin
switch(config)# username sysin shell bash
switch(config)# copy r s

下一步

以后可以直接使用 SSH 访问,串口可用于 SSH 无法访问时候问题排查。
