IPv6 Implementation
Specifications
The IPv6 implementation conforms to the following IETF documents:
Operational Information
IPv6 enabled devices can auto configure their IPv6 address. This happens automatically
whenever there is an IPv6 enabled router on the subnet to which the device is connected. The
printer unique ID is obtained from the Ethernet MAC address. The router may advertise
multiple network prefixes, depending on the network configuration. The Network summary
page displays all the above addresses, if they exist. If only the Local Link address (starting with
“xFE80...”) is displayed, that is an indication that the link is not connected to a router
(gateway). No manual configuration of IPv6 addresses is supported, nor is there support for
DHCPv6, and the printer does not register its IPv6 address with DNS.
Upper Level Protocols such as UDP, TCP run with either IPv4 or IPv6. For instance, a print job
can be sent to the printer over IPv4 or IPv6. Similarly the EWS or SNMP can be accessed over
IPv4 or IPv6. IPv6 and IPv4 coexist independent of each other. They can be Enabled/Disabled
in any combination. They are both enabled by default. In cases where a particular network is
configured to run only one IP version, it makes sense to disable the other one (for better
resource utilization).
SNMP
SNMP can be used to manage any network device. SNMP is a protocol that allows an SNMP
manager (the controller) to control an SNMP agent (the controlee) by exchanging SNMP
messages. The main purpose of an SNMP message is to control (set) or monitor (get) the
parameters in a network device.
In SNMP, a parameter is an instance of a more generic object. For example, an SNMP agent
may have several instances of an object. An SNMP manager can set or get the value for each
object instance (each parameter).
