Hi Illya,
Hope you're doing well,
I'm starting Huawei simulator and it's running but during the polling it always crash with following :

Can you please help me to identify the root cause of such crash ?
Thanks,
can you share the mib file?
Thanks,
Hi KexZh,
I'm attaching sapwalk of the device. I suspect an issue in it due to small size and maybe missing standard OIDs

Hi @mhouf ,
can you try with the files which generated by snmpsim-record-commands or netsnmp?
snmpsim-record-commands --agent-udpv4-endpoint=demo.snmplabs.com
--output-file=./data/public.snmprec
Thanks,
Hello KexZh,
I'm not sure if I understand what you mean, I'm using the following command to start the simulator 👍
/usr/bin/python /usr/bin/snmpsimd.py --agent-udpv4-endpoint=x.x.x.x:161 --data-dir= --v2c-arch --process-user=xxxx --process-group=xxxx --daemonize --pid-file=/opt/SNMP_repo/Logs/snmpsimd-Huawei_315_2.pid --logging-method=file:/opt/SNMP_repo/Logs/Huawei_315_2.log
Do you mean execute data.py on the sapwalk to generate .rec file?
Please explain further.
BR,
Mo

How you collect the output you shared before?
snmpsim-record-commands, netsnmp or a thirdparty tool?
Hello KexZh,
The output of the simulation is the one mentioned in snmpsim command "/opt/SNMP_repo/Logs/Huawei_315_2.log"
The simulation start and have PID but during the start of the polling from 3rd party software, it crashes, and the simulation log mention this -:

Yes, you're right.
Depends on this I suggest you to polling the SNMPwalk data with
snmpsim-record-commands --agent-udpv4-endpoint=demo.snmplabs.com
--output-file=./data/public.snmprec
or NETSNMP instead of sapwalk?
Hi KexZh,
Thanks for your input, issue fixed after converting exiting sapwalk to snmp.rec using data.py and using the below options -:
--ignore-broken-records --deduplicate-records
Thank you,
Mo
