I have been unable to collect and store SNMP ifPhysAddress correctly as it either shows as blank or bad data.

When performing the snmpwalk on a specific oid I get the following:

snmpwalk -v2c -c '8nBAToGrH8p0AknFd9oR' 10.220.45.8 .1.3.6.1.2.1.2.2.1.6.8
IF-MIB::ifPhysAddress.8 = STRING: 6c:b2:ae:98:a3:1c

When defining the Zabbix SNMPv2 item .1.3.6.1.2.1.2.2.1.6.8 I get the following:

l????

When query the database for the raw data I get the following:

l????\x1C

If the item is defined as an SNMPv3 item the data is returned as blank.
