While using VMWare workstation as a platform in running vIOS/IOSv (Cisco Virtual IOS) we usually use the pipe method to access the Virtual Serial console with the devices but using undocumented feature we could access it with any telnet capable terminal software. We only need to edit the VMware vmx file (ref: vnetlabs.com/….) and add the following
serial0.fileType = "pipe" serial0.fileName = "\\.\pipe\com_1"
serial0.fileType = "network" serial0.fileName = "telnet://0.0.0.0:10000"
You will notice that serial port type indication report a “unrecognized type” but don’t worry about it since it is undocumented so it is expected. Now we will try to access the vIOS via Telnet 127.0.0.1 port 10000
With this setup we could now use our favorite Terminal Software without needing some specials sofwares or feature to access the console of vIOS routers.
