What are the Exec and Virtual Exec Processes?
The Exec process in Cisco IOS software is responsible for communication on the tty lines (console, auxiliary, asynchronous) of the router. The Virtual Exec process is responsible for the vty lines (telnet sessions). The Exec and Virtual Exec processes are Medium-priority processes, so if there are other processes that have a higher priority (High or Critical), the higher priority processes get the CPU resources.
