Configuring virtual terminals.

Virtual Terminal lines are configured so more than 1 session can take place, say for example a switch needs a lot of configuration applied to it, maybe we need to 3 of 4 people to login and share the configuration work. On a CISCO 1841 we can have up to 808 virtual lines , why ? Well if we have 2 possibilities to connect via the AUX or Console port this allows only 2 and we need to be standing near the router because of the serial cable, so if we wanted the 4 or 5 admins to configure the router then we need another method this is where the line line vty command is useful.

Use the following command line vty 0 4 this will allow us to connect to the router at distance of the network and allow 5 connections.
