I've come across a strange problem today with dropped packets through an 871. Both Vlan1 and F4 show a large number of input drops, but no other errors. CEF is enabled on both interfaces, and I have also tried with fast switching and increasing the input buffer to 4000, which stops the interface input drops increasing, but doesnt stop the dropped ping packet problem. Any ideas would be greatfully received!
From F4 to a host on Vlan1:
Sending 1000, 100-byte ICMP Echos to 88.21.n.n, timeout is 2 seconds:
By default, all layer 2 ports are in dynamic desirable mode, so the layer 2 port tries to form a trunk link and sends out DTP packets to the remote device. When a layer 3 interface is connected to a layer 2 switchport, it is not able to interpret these frames, which results in Input errors, WrongEncap errors, and Input queue drops.
In order to resolve this, change the mode of the switch port to static access or trunk as per your requirement.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
