AltocumulusDrop reason counters.rx_portd_rdisc
Hello everyone, i'm asking for your help in order to undestand some values i'm seeing when looking for the drop reason in my big ip devices I have 2 big ip i5600 devices in an Active/Standby conf...
Hello Victor,
RPORTD is incremented when a port’s spanning tree state is not in the forwarding state, while RDISC is incremented for packets discarded due to ingress buffer availability. This doesnt necessarily mean TMM traffic.
BPDU packets coming from a switch which will register this counter and increment the counters.rx_portd_rdisc.. this can likely be determined by run tcpdump on the interface. Please take all ***precautions*** when running tcpdump
