If you attach the walk of “‘.1.0.8802” that should be enough to see what’s going on.
Please use that command (and adapt your auth details)
/usr/bin/snmpbulkwalk -v3 -l authPriv -n ' "" ' -a SHA -A myAuth -u myUser -x AES -X myPriv -OQun -m LLDP-MIB -M /opt/librenms/mibs:/opt/librenms/mibs/lenovo udp:10.255.255.166:161 .1.0.8802 | ./pbin.sh
(First check that the SNMPWALK command works OK, and then pipe the result to the pbin script, and you can then post here the link to the data. )
