In this post we will learn how to configure telnet on cisco switch when working on ipv6 . Many of you might know how to configure telnet on cisco switch in ipv4 . But when it comes to ipv6 mostly will fail .
MultiLayer Switch (MLS) is a network device by Cisco that provides Layer 3 (L3) switching in conjunction with existing routers. It has the ability to operate at higher layers of the OSI reference model, unlike the Data Link Layer (DLL) which are traditionally used by switches.
In the diagram as you can see multilayer switch have been used to configure telnet on cisco switch . As you by default vlan id is 1 . So we will give ip by using vlan and then we will try to access switch through telnet . But this not for ipv4 . This lab is specially for ipv6 telnet configuration cisco switch .
MULTILAYER SWITCH CONFIGURATION
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#int vla 1
Switch(config-if)#ipv6 add 2001::1/64
%LINK-5-CHANGED: Interface Vlan1, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan1, changed state to up
Switch(config)#line vty 0 5
( 123 will be the password when i will access through telnet )
- Click on one of your laptop and go to DESKTOP > IPCONFIGURATION
- Give ip in ipv6 area .
- Same way give ip to all machine .
- Open command prompt and type telnet ipaddress
- Like in this lab , telnet 2001::1
When you are connected it will ask password to access switch . Type right answer and connect to switch through telnet .
