[j-nsp] PIC Oversubscription Show Commands

[Eduardo Barrios]

Yes if traffic goes in/out of the same PIC. We have some IQ2Es on some M10is. The numbers were 4:1 when testing with a Spirent, but smaller MTU size packets @ 64 and 128 the transfer rate is less.



Can't recall any commands for the PIC, just recall seeing no drops on the interface queues and knowing the loss was due to the traffic flow oversubscribing the PIC.



Thanks,

Eduardo

My understanding is the 4x1GE IQ2 PIC is oversubscribed 4:1.  Are there any

commands to see if there is congestion on the PIC?



Really, I'm wondering if there are any commands that show congestion within

the switch itself (ie PIC to/from FPC, FPC to/from CFEB, etc.,)



I can't seem to find any.



Thanks,
