Etape 1 : Donner une adresse IP au switch
switch>ena
switch#conf t
switch(config)#inter vlan1
switch(config)#ip address 192.168.1.10 255.255.255.0
switch(config)#no shut
switch(config)#exit
switch#sh ip int brief
Interface              IP-Address      OK? Method Status                Protocol

Etape 2 : Envoyer le fichier via TFTP

Dans cet exemple mon fichier se nomme : c3750me-i5-mz.122-35.SE5.bin

Une fois votre serveur TFTP prêt, nous pouvons envoyer le ficher

switch#copy tftp flash
Address or name of remote host[]? 192.168.1.100
Source filename[]? c3750me-i5-mz.122-35.SE5.bin
Destination filename [c3750me-i5-mz.122-35.SE5.bin]?
