I've read in multiple places that you can increase the number of virtual terminal lines by typing "line vty [some high number]". When I try on a 2511 with IOS 12.2 installed, it responds with an error: "Invalid input detected". When I try "line vty ?", it responds with "<0-4> First Line number". When I try "line vty 0 ?", it responds with "<1-4> Last Line number". How can I get more than 5 virtual terminal lines? Do I have to enable protocol translation or something? If so, how do I do that?
Thanks in advance,
