We have a single switch port that goes into a 3rd paryt MPLS cloud that then has several remote switches connected to it. Do to this, it will show multiple CDP neighbor devices on that one port since we don't manage the equipment in the middle. What I have noticed is that Nedi will discover one if the devices but then ignore the rest. This is what shows up in the debug:
DIPR:440406016.9371653 on Et9/2
CDP :Switch1,Fa0/0/0 10.10.10.1 on Et9/2
DIPR:440406016.7077895 on Et9/2
CDP :Ignoring duplicate neighbor Switch2 (set MACflood threshold to allow)
DIPR:440406016.6291462 on Et9/2
CDP :Ignoring duplicate neighbor Switch3 (set MACflood threshold to allow)
DIPR:440406016.12320770 on Et9/2
CDP :Ignoring duplicate neighbor Switch4 (set MACflood threshold to allow)
DIPR:440406016.5767172 on Et9/2
CDP :Ignoring duplicate neighbor Switch5 (set MACflood threshold to allow)
DIPR:440406016.720897 on Et9/2
CDP :Ignoring duplicate neighbor Switch6 (set MACflood threshold to allow)
DIPR:440406016.13828099 on Et9/2
CDP :Ignoring duplicate neighbor Switch7 (set MACflood threshold to allow)
I have a MAC flood threshold set but is there something specific that it needs to be set to in order for this to be allowed?
Thanks
