Configuring Virtual Terminal Lines for Remote Console Access
Virtual terminal (vty) lines are used to allow remote access to the router. This section shows you how to
configure the virtual terminal lines with a password, so that only authorized users can remotely access
the router.
The router has five virtual terminal lines by default. However, you can create additional virtual terminal
lines as described in
Cisco IOS Terminal Services Configuration Guide, Release 12.4
. See
Line passwords and password encryption is described in the
Cisco IOS Security Configuration Guide,
Release 12.4
. See
http://www.cisco.com/en/US/docs/ios/security/configuration/guide/12_4/sec_12_4_book.pdf
.
Note
To secure the vty lines with an access list, see
