I just finished taking a Cisco exam and one of the questions on the exam had to do with the number of default Telnet session allowed to a Cisco switch. I know you only set or configure the "line vty 0 15" interfaces/session to allowed a total of 16 but that was not one of the answers. I choose six because of the my experience seeing the "line vty 0 5" command configured on many a switches.

Any feedback would be greatly appreciated.

-P.S.

That is the standard for most switches, 0 15. I have seen 'line vty 0 4' on a lot of routers and equipment. perhaps 5?

I thought the default is "line vty 0 4"

I believe that is the case. I put "5" as my answer due to the fact that the # starts at 0.

Thanks!

Was one of the options 0? By default you can't telnet to a Cisco switch until you set a password on the vty lines either directly or via AAA.

is 5 lines, 0-4

you can not get any connections unless passwords are set. So if the question was how many connections can be made, unless passwords are set, the # is 0. A telnet request to a router with no passwords set will be refused.

Enterprise, depending on IOS ver is, I believe, 1180. Still 0 connections unless passwords are set.
