Hi, nobody an idea? Tried Mini Protocol Analyzer but as far as I see I cannot combine with a MAC address ACL. In the meantime I got a server connected to the router and could export the traffic via SPAN but still see no unusal broad-/multicast-spikes.
Can anybody confirm that the physical interface bandwidth is used for the percentage calculation and not the current traffic? I.e. 0.35% on a 10Gbit interface with 200MBit traffic will make storm control drop everything above 35MBit (10000MBit*0.35%) and not 0.7MBit (200MBit*0.35%), correct? kind regards Rolf > Hello, > > I have a switchport interface (6704 card, Sup2T, IOS 15.1(2)SY1) with a > few vlans (L2 + L3 mixed) on it that drops packets caused by storm > control. > > sh interfaces counters storm-control: > Port UcastSupp % McastSupp % BcastSupp % > TotalSuppDiscards > Te9/3 100.00 0.35 0.35 > 5800188 > > I now would like to find out on which vlan I receive them. > Unfortunatelly the non-unicast counters for all vlan-interfaces show 0, > example: > > sh int vl300 | inc cast > L2 Switched: ucast: 8023503 pkt, 2642606815 bytes - mcast: 0 pkt, 0 > bytes > L3 in Switched: ucast: 120002757406 pkt, 16510187670768 bytes - mcast: 0 > pkt, 0 bytes > L3 out Switched: ucast: 75127991555 pkt, 65410581551697 bytes - mcast: 0 > pkt, 0 bytes > Received 0 broadcasts (0 IP multicasts) > > sh vlan id xxx counters also schows zeroes only for all vlans: > Vlan Id : 300 > L2 Unicast Packets : 8023503 > L2 Unicast Octets : 2642606815 > L3 Input Unicast Packets : 120008317418 > L3 Input Unicast Octets : 16512241861042 > L3 Output Unicast Packets : 75144910816 > L3 Output Unicast Octets : 65423693432219 > L3 Output Multicast Packets : 0 > L3 Output Multicast Octets : 0 > L3 Input Multicast Packets : 0 > L3 Input Multicast Octets : 0 > L2 Multicast Packets : 0 > L2 Multicast Octets : 0 > > Is there a way to enable those counters or to find out which vlan receives > those peaks without exporting the traffic to another system > (SPAN,netflow,...)? > > kind regards > Rolf > > > _______________________________________________ > cisco-nsp mailing list [email protected] > https://puck.nether.net/mailman/listinfo/cisco-nsp > archive at http://puck.nether.net/pipermail/cisco-nsp/ > _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
