Settings Common to the Network Protocols
The machine supports the SNMP v. 1 and SNMP v. 3 management functions. You can use them
simultaneously. The [Read Only]/[Read/Write] functions of SNMP v. 1 and the security functions of SNMP v.
3, such as an encrypted communication path, enable you to manage devices more securely.
The available combinations of SNMP v. 1 and SNMP v. 3 functions you can use are shown below:
SNMP v. 1 SNMP v. 3 Description
Use SNMP v. 1 MIB Access
Permission
Use SNMP v. 3
On Read/Write On/Off You can set or browse each item of the
machine with a utility that uses SNMP v. 1 to
obtain information.
As the write access with SNMP v. 1 is enabled,
the security functions of SNMP v. 3 are not
available, regardless of the settings for <Use
SNMP v. 3>.
On Read Only On You can only browse each item of the
machine with a utility that uses SNMP v. 1 to
obtain information.
Only users who have been assigned access
rights can set each item of the machine with
a utility that uses SNMP v. 3.
On Read Only Off You can only browse each item of the
machine with a utility that uses SNMP v. 1 to
obtain information.
Off - On Only users who have been assigned access
rights can set or browse each item of the
machine with a utility that uses SNMP v. 3.
Off - Off You cannot set or browse each item of the
machine with a utility.
If you want to use a Canon printer driver or utility, press [On] for both <Use SNMP v. 1> and [Enable
Dedicated Port].
You can restrict the IP addresses of computers on which items can be set or browsed. If you restrict the IP
addresses, it is not possible to set or browse detailed information concerning the machine on computers
other than those whose IP addresses are allowed, even if <Use SNMP v. 1>, <Use SNMP v. 3>, and [Enable
Dedicated Port] are 'On'. For details, see “TCP/IPv4 Settings,” on p. 5-3 or see “TCP/IPv6 Settings,” on p. 5-9.
