Enabling and Disabling Protocols

Specify whether to enable or disable the function for each protocol. By configuring this setting, you can specify which protocols are available and so prevent unauthorized access over the network. Network settings can be specified on the control panel, or by using Web Image Monitor or Device Manager NX. In the case of Device Manager NX, use it to start Web Image Monitor and configure the settings from there.

Protocol	Port	Setting method	When disabled
IPv4	-	Control panel Web Image Monitor Device Manager NX	All applications that operate over IPv4 cannot be used. IPv4 cannot be disabled from Web Image Monitor when using IPv4 transmission.

HTTPS	TCP:443	Web Image Monitor Device Manager NX	Functions that require HTTPS cannot be used. You can also make settings to require SSL transmission using Web Image Monitor.
SNMPv1,v2	UDP:161	Web Image Monitor Device Manager NX	Functions that require SNMPv1, v2 cannot be used. Using the control panel or Web Image Monitor, you can specify that SNMPv1, v2 settings are read-only, and cannot be edited.
SNMPv3	UDP:161	Web Image Monitor Device Manager NX	Functions that require SNMPv3 cannot be used. You can also make settings to require SNMPv3 encrypted transmission and restrict the use of other transmission methods using Web Image Monitor.
