Most enterprise networks do not allow or desire Telnet to be used for terminal access to the switch. SSH is a more secure and flexible method to gain access to the switch remotely. The guide below shows a basic configuration to support SSH version 2 connections.
Global SSH Configuration
Switch>En Switch# Switch#conf t Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#aaa new-model Switch(config)#username AAAA privilege 15 secret Livewire Switch(config)#ip http authentication local Switch(config)#ip domain-name AXIA.LOC Switch(config)#crypto key generate rsa The name for the keys will be: Switch.AXIA.LOC Choose the size of the key modulus in the range of 360 to 4096 for your General Purpose Keys. Choosing a key modulus greater than 512 may take a few minutes.
How many bits in the modulus [512]: 1024 % Generating 1024 bit RSA keys, keys will be non-exportable... [OK] (elapsed time was 4 seconds)
The serial port can be treated as an emergency way to gain access to your switch. For this reason, you may find it appropriate to omit any password requirements
Switch#conf t Switch(config)#line con 0 Switch(config-line)#no password Switch(config-line)#end Switch#wr Building configuration... [OK]
