Hi @Simran,

Please, get the output of ./tools/gtp5g-tunnel list qer

If the command didn’t work then lates gtp5g source code implemented /proc interface

  1. cd /proc/gtp5g
  2. sudo echo upfgtp 1 > ./pdr
  3. sudo cat ./pdr

-where, sudo echo #gtpinterface #pdrId > ./pdr

You will get the output like below
xyz:/proc/gtp5g$ sudo cat pdr
PDR:
ID : 1
Precedence: 255
OHR: 1
Role Addr4: 0x000000
PDI UE Addr4: 0x3c3c0001
PDI TEID: 0x000001
PDU GTPU Addr4: 0x10100364
FAR ID: 1
QER ID: 1
UL Drop Count: 0x0
DL Drop Count: 0x0

If nothing works then add debug code in gtp5g.c to trace encap of GTP-U header.
