| Well, just in case you are new to the word | | | | Defines a static host name-to-address mapping in |
| "telnet"; telnet is an Application Layer protocol that | | | | the host name cache. |
| can be used to make direct connections (using | | | | Step #4 |
| telnet sessions) to a Cisco router or from a Cisco | | | | |
| router. It doesn't matter whether you're using the | | | | 4. Router(config)#line vty 0 4 |
| IPv4 protocol or the IPv6 protocol, "telnet" | | | | Creates a vty interface and places router into |
| performs in the same manner. | | | | Line configuration mode. |
| A network administrator can use "telnet" to make | | | | Step #5 |
| the following different types of direct connections | | | | |
| (telnet sessions): | | | | 5. Router(config-line)#password ittechtips |
| - Host to Router | | | | Creates a (ittechtips) password that enables |
| - Router to Router | | | | Telnet. |
| - Router to Host | | | | Step #6 |
| In this article, I'm going to show you how to | | | | 6. Router(config-line)#login tacacs |
| enable "telnet" on a Cisco IPv6 router, so you'll be | | | | Informs the router to use the tacacs server for |
| able to directly connect to it via telnet sessions | | | | password checking at login. |
| and I'm also going to show you how you can | | | | Step #7 |
| initiate a "telnet" session from a Cisco IPv6 | | | | |
| Router. | | | | 7. Router(config-line)#ipv6 access-class vty-acl in |
| Here are the steps needed to enable "telnet" on a | | | | Adds an IPv6 access list named vty-acl to the line |
