- 5. 1.2 Jeimaršrutizatoriaus konfigūraciją reikęs keisti, tai reikia pereiti į administratoriaus (privilegijuotą) režimą. Naudokite šita komanda: Router> enable Password: Router# ( Privileged mode prompt )
- 6. 1.3 Dabargalima keisti maršrutizatoriaus konfigūracija. Kad tai padaryti reikia įvesti komanda: configure terminal arba conf t Šita komanda galima įvesti jeigu Jūs esate privilegijuotame režime. Router# configureterminal Enter configuration commands,one per line.End with Ctrl-Z Router(config)# ( Konfigūravimorežimas)
- 7. 1.4 Kadišeiti iš konfigūravimo režimo, Jūs galite pasinaudoti komanda exit (ex) arba klavišų kombi-nacija Ctrl-Z . Kad išeiti iš privilegijuoto režimo galima pasinaudoti disable komanda. Router(config)#exit Router#disable Router>
