Configure a Network Serial Console Port
For a better console experience, you can configure a network serial port singly or attached to a virtual serial port concentrator (vSPC) for console access. See the VMware vSphere documentation for details about each method. On the ASAv, you must send the console output to a serial port instead of to the virtual console. This section describes how to enable the serial port console.
Procedure
1. Configure a network serial port in VMware vSphere. See the VMware vSphere documentation.
2. On the ASAv, create a file called “use_ttyS0” in the root directory of disk0. This file does not need to have any contents; it just needs to exist at this location:
	disk0:/use_ttyS0
–From ASDM, you can upload an empty text file by that name using the Tools > File Managementdialog box.
–At the vSphere console, you can copy an existing file (any file) in the file system to the new name. For example:
ciscoasa(config)# cd coredumpinfo
ciscoasa(config)# copy coredump.cfg disk0:/use_ttyS0
3. Reload the ASAv.
–From ASDM, choose Tools > System Reload.
–At the vSphere console, enter reload.
	The ASAv stops sending to the vSphere console, and instead sends to the serial console.
4. Telnet to the vSphere host IP address and the port number you specified when you added the serial port; or Telnet to the vSPC IP address and port.
