Appunti sull’upgrade di una IOS Cisco

Appunti sull’upgrade di una IOS Cisco

In questo esempio vi mostrerò come effettuare l’upgrade su uno Switch Cisco 2970.

Installiamo Tftpd32 su un PC Windows e nella home directory del demone TFTP Copiamo il file della IOS che in questo caso è c2970-lanbase-mz.122-44.SE6.bin.
Dopo impostiamo sulla scheda di rete l’ip 192.168.2.2/24 e subito dopo inseriamo in console i seguenti comandi:

Sw1#conf t
Sw1(config)#int vlan 1
Sw1(config-if)#ip address 192.168.2.1 255.255.255.0
Sw1(config-if)#no shut
Sw1(config-if)#exit
Sw1(config)#end
Sw1#
Sw1#ping 20.20.20.2
 
Sw1#show flash
