To make ports FastEthernet 1/1 to 1/4 part of a new VLAN, number 2:

• Telnet to the Catalyst.
• Login and then enable.

Before doing anything, do a write mem so you can easily recover from any mistakes you make (reload).

vlan database
vlan 2
quit
vlan database
vlan 2 name The New Vlan!
quit
conf t
interface range fastethernet 1/1 - 4
switchport access vlan 2
end

1. Power cycle the router.
2. Send a BREAK within 60 seconds.
3. From ROM mode, change config register to 2142. (confreg 0×2142)
4. Reboot router.
5. Get into Priv Exec (enable) mode.
6. Load up config with “copy start run”.
7. Change password and reset config-register to 2102. (config-reg 0×2102)
8. Save config with “copy run start” and reload.

Done!

We will be creating a reverse telnet session on the console port.

• Connect a 9600/8/N/1 terminal to the Cisco router console port.

conf t
Line AUX 0
Speed 9600
Modem inout
Modem DTR
Flowcontrol Hardware
Transport input all
Transport output all
WR
CTRL-Z
exit

You should now be able to telnet to the AUX port.
