Povolení SSH
- v Maintenance > Backup and Update Manager stáhnout (Backup) startovací konfiguraci (Startup configuration) - upravit jej v textovém editoru - před řádek s configure přidat řádek ip telnet server enable - soubor nahrát opět v Maintenance > Backup and Update Manager jako startovací konfiguraci (Startup configuration) - restartovat switch - přihlásit se do switche přes telnet a spustit následující příkazy pro povolení SSH a změnu hesla admina: enable configure crypto key generate rsa crypto key generate dsa exit ip ssh server enable ip ssh protocol 2 passwords min-length 0 username admin password NOVE-HESLO-ADMINA write memory confirm quit - přihlásit se do switche přes SSH a zakázat telnet: enable no ip telnet server enable write memory confirm quit
