Hi I have an application which is sending data(FAST) to from pc to HW. It works fine. However when I have this Z9100-on switch between HW and pc, the switch is stopping the data. I have tried various settings with flow control and storm control but it doesn't help.
If I print the 'show hardware drops interface' of the interface, I cans see that Ingress Drops,Packets dropped by FP, and Port bitmap zero Drops increase by for example 1000 if I send 1000 packets.
Do you have any tips how to fix this problem ? Is this a HW buffering issue. What can I do to fix this ?
Drops in Interface Hu ...:
Ingress Drops : 468574 IBP CBP Full Drops : 0 PortSTPnotFwd Drops : 0 IPv4 L3 Discards : 0 Policy Discards : 1864 Packets dropped by FP : 131709 (L2+L3) Drops : 0 Port bitmap zero Drops : 468574 Rx VLAN Drops : 21 --- Ingress MAC counters--- Ingress FCSDrops : 0
thanks for your time.
Solved! Go to Solution.
What OS version is the switch on? How is the port configured? Are there any ACLs that would block traffic?
Application Software Version: 9.14(1.3) Operating System Version: 2.0
interface hundredGigE ... no ip address mtu 9416 portmode hybrid switchport vlan-stack trunk no shutdown
There is nothing configured that would block traffic.
What speed is the PC NIC, is it also 100G?
Its really hard to find documentation related to "show hardware drops interface tengigabitethernet x/x" output
