media cards packet loss

[1998xj8]

i have packet loss errors on 2 media card 32S.. i have MC32 non S with no packet loss.. weird...
Anyone have any experience with isolation and troubleshooting this kind of issue ?

Check that you have the most current firmware loaded on the MC32S. Also check to make sure thay you are using auto-negotiation on both ends of the ethernet ports.

You talking QoS or how exactly are you determining packet loss?
Could be card/daughterboard vintage as you still have to be careful with that (old Nortel knowledge). I agree with Gweb first though just throwing out other opinion in case it helps.

Do you guys know if this is a recent vintage ?

where are you seeing the packet loss? on the switch port? or on the CLI of the card? and does it say "Dropping packets" or packet loss?

I had a matrix on what was compatible ... if only I could find it to answer you I was thinking AA was compatible with AB so it is likely some network issue or something.

You can try hard setting duplex on the ends as I have seen Cisco equipment work better when hard set - just saying - we struggled with auto for years!

usually the packet loss is higher like 3 percent but an example
QOS007 Unac pkt loss:[PL:99.9 LT:0 JIT:2 R:0]
Near [10.88.40.32:5220],TN[028 0 14 10],NZ[1:1]
Far [10.37.40.32:21012] TN[000 0 00 00], VPNI:Zone[4:1]

That looks like 99.9% packet loss to me

We have been ignoring these unless someone is complaining in all honesty. Good luck trying to fix it.

QOS0007 QOS packet loss: [packet loss value that exceeds unacceptable threshold],
[sourceIP:source port], [source TN], [source zone], [destination IP:destination
port], [destination TN], [destination zone]. where:
packet loss value = percentage of packets not received
source TN = originating set’s TN in l s c u format (large system) or c u format
(small system)
destination TN = terminating set’s TN in l s c u format (large system) or c u
format (small system)
