Durchführen einer Paketerfassung Ich sehe immer wieder seltsame "DEC MOP Remote Console" -Frames:

Die Quell-Mac-Adresse stammt von einem Cisco-Router. Decnet ist jedoch auf dem Router deaktiviert und die Transporteingabe auf Telnet eingestellt:
router# show decnet
% DECnet is not enabled
router# show run | begin line vty
line vty 0 4
transport input telnet
Wie kann ich verhindern, dass dieser Router diese Remote-Konsolenrahmen sendet?
