•
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:
•
If you want to use a Canon printer driver or utility, press [On] for both <Use SNMP
v. 1> and [Enable Dedicated Port] (for IPv4 only).
•
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] (for IPv4 only) are 'On'. For details, see "TCP/IP Settings (IPv4),"
on p. 3-3 or "TCP/IP Settings (IPv6)," on p. 3-18.
