Titolo: DHCP lento...

Salve ragazzi..ho postato un messaggio giorni fa.. ma senza nessuna
risposta..
Ho comprato un cisco 857..tutto va bene, ma quando collego un host in
DHCP,
questo ci mette più o meno un minuto per acquisire l indirizzo ip..
Quale può essere il problema..?
spero mi rispondiate,perchè se è un problema del router posso ancora
mandarlo indietro..
Grazie Vito

Aggiungi a tutte le FastEthernet questi due comandi:
no cdp enable
spanning-tree portfast
e dovrebbe dare l'indirizzo IP immediatamente
