Command Doubts

[BlackJackiv2008]

Hi Mr Todd Lammle,

I have doubt on this IOS command line as mentioned in Chapter 4 while i m working on RouterSim Lab:

router(config)#line vty 0 4
(what is meant by the '4'?)

router(config)#encrypto key generate rsa modulus 380
(the 'modulus' does not work in RouterSim, also,what is meant by key modulus here?)


Thanks.

When you generate RSA keys, you will be prompted to enter a modulus length. A longer modulus could offer stronger security but takes longer to generate and takes longer to use. A length of less than 512 bits is normally not recommended. (In certain situations, the shorter modulus may not function properly with IKE, so Cisco recommends using a minimum modulus of 1024 bits, that is the default.)
The range is 360 bits 512 bits 1024 bits and 2048 bits.


Virtual terminal lines are used to allow remote access to a router. A virtual terminal line is not associated with either the auxiliary or console port; instead, it is a "virtual port" on the router. The router has five virtual terminal lines, by default. (0-4)

Has anyone here used the spanning-tree portfast trunk command on a blade chassis switch for a virtual port-channel trunk to a virtual server?Dave
