Ces commandes permettent d'afficher les voisins, d'afficher différentes statistiques, de faire un ping vers une interface ou encore de vérifier l'état des processus.

Comment afficher les voisins?
Il peut être utile d'afficher les voisins (en général d'autre routeur relié). Cisco utilise le protocole CDP (cisco discovery protocol) pour afficher les informations sur les voisins. Il faut donc pour que la commande fonctionne que le protocole cdp soit activé sur les routeurs.La commande suivante active le protocole cdp puis affiche les voisins.
R2(config)#cdp run
R2(config)#exit
R2#show cdp neighbors
Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge
S - Switch, H - Host, I - IGMP, r - Repeater
Device ID Local Intrfce Holdtme Capability Platform Port ID
R1 Eth 1/0 125 R 7206VXR Eth 1/0
R2#
Il est aussi possible d'afficher les détails sur le voisin, notamment l'adresse IP et le modèle de ce dernier en filtrant sur un port ou sur le nom d'un voisin.
