TMA-PRINTER-SNMPV3
Ensure SNMP is SNMPv3 only with authentication and privacy (or disabled)
说明
SNMPv1/v2c community strings (public/private by default) are sent in clear text and often allow configuration writes, including resetting the admin password on some models. SNMPv3 authPriv protects management traffic.
