SNMP down !!!!

salut,
il y a beaucoup de chose qui peuvent faire que snmp ne fonctionne pas.
la première c'est de vérifier tcpip en faisant un ping vers l'équipement.
la seconde c'est de vérifier la chaines de communauté (genre de mot de passe) sur le manager et sur l'agent.
Après, si c'est snmp V3, il y a encore d'autres choses, le cryptage.

saluuut tt l monde,
merci brupala sur ta reponse!!
concernant tcpip j'ai fait un ping et ça marche nichel..
et aussi j'ai un snmp v2c..
mais ce truc de communauté je sais pas quoi faire dessus !!
svp vous pouvez m'expliquez mieux !! je suis encore coincé et je suis debutant !!!
merciiiiiiiiiiiiiiiiiiiiiii

Merci de continuer et de rester sur cette discussion!

salut;
je vais expliquer mieux mon problème:
apres la configuration du protocol SNMP et l'installation de NMIS, le localhost est Up trankil, j'ai les informations les interface... Mais qd je rajoute un équipement (Routeur, PC ...) il me lance "SNMP ERROR", alors lors de l'ajout et qd je fait "add and Update Node" il me donne ça:

Running update on node PostY
