Rx Frag on a particular port printer connected

Hi All,

I am facing an issue regarding incremental packet drop on a particular port with Rx Frag value is also increasing, I have checked/alter cables but nothing rectified following is the packet statistics of that port

Port Packet Statistics
Port Link Packet Sizes
State 0-64 65-127 128-255 256-511 512-1023 1024-1518 Jumbo
================================================================================
44 A 408462663 44814 4295 2711 715 1439 0
================================================================================

My switch model is X440G2-48p-10G4

The same model printer is connected to another same model switch but there is no issue, please suggest.

Have you already connected the printer to another port? Do you see the same behavior on the other port?

Do you see rx/tx errors?

yes I have changed the port in switch and noticed the same behaviour, I mainly faced following 2 problems

when i do show ports congestion it is showing incremental packet drops on the port in which the printer connected.

And when I do show ports rxerrors it showing Rx Frag counter on the same port other parameters are ok.

Did you check if both (switch and printer) is using full-duplex and the same port speed?

Compare the network setting on the running and not running printer.

yes both switch and printer using same speed(1 gbps) duplex full in auto mode, following is the output of port config
