7.2 Disabling SNMPv1/v2
If you need SNMPv1 or SNMPv2, then use these protocols only in environments protected from
eavesdropping. SNMPv1 and SNMPv2 do not use encryption. The SNMP packets contain the
community in clear text. We recommend using SNMPv3 in the device and disabling the access
using SNMPv1 and SNMPv2.
Perform the following steps:

Open the
Device Security > Management Access > Server
dialog,
SNMP
tab.
The dialog displays the settings of the SNMP server.

To deactivate the SNMPv1 protocol, you unmark the
SNMPv1
checkbox.

To deactivate the SNMPv2 protocol, you unmark the
SNMPv2
checkbox.
