le router cisco 887 VA-K9 ne diffuse pas les adresses IP au reseau local

Question

bonjours

j ai une question j ai achete un routeur cisco 887VA-k9 , je le configuré avec la configuration ci-
dessous

si je le lier avec mon pc portable sur l un de ses ports directement ça marche toute est bien ( la
connexion internet + mon pc portable à une addresse ip) , au contraire si je le lier avec le switch
(procurve 1700-24 ) de mon reseau local rien ne fonctionne (pas des adresse ip sur mes poste interne+pas
d internet aussi pas d'une connexion de mon pc lier au switch vers le routeur)

sachant que j ai pas pas des vlan

Merci

bonjour

si j'ai bien compris quand tu connectes l' une des interfaces Ethernet 0,1,2,3 sur le switch HP rien ne marche et si tu connecte ton PC sur ces interfaces ca marche bien.

si c le cas alors je pense q tu dois utiliser un cable reseau croise (coss cable) entre le routeur et le switch car tu es en train de relier switch a switch. dans ce cas un cable droit ne fonctionne pas si ton switch n est pas intelligent (fonction MDX)

si ca ne marche pas toujours, donne ton PC une adresse statique 192.168.2.20 par exemple et essaie de pinguer ton routeur .

merci pour tout vos efforts et tous vos réponses;

mais je fais les solution proposés , toujours reste le même problème , le routeur vers l extérieur ( l internet) ça marche ; mais vers le switch lier aux PC , le routeur ne diffuse pas les adresses ip

Merci

ohassairi · ‎04-15-2018

sur quel port tu as connecte le cable de casacde ? car je vois toutes les interfaces down:

FastEthernet0 unassigned YES unset down down

FastEthernet1 unassigned YES unset down down

FastEthernet2 unassigned YES unset down down

FastEthernet3 unassigned YES unset down down

**********************************************

mais je trouve que :

mes poste pc sans adresse ip

si je connecte mon pc avec une adresse statique directe avec mon routeur , j ai l accès à internet mais se déconnecte de temps en temps.

donc

est ce que ma config est juste?

pourquoi mon dhcp de mon routeur ne diffuse pas l adresses ip aux pc de mon reseau local

Merci
