• SerialNumber (“SerialNumber=P01238710163241048”)
• IP (“IP=192.168.0.1”)
• NetMask (“NetMask=255.255.255.0”)
• Gateway (“Gateway=0.0.0.0”)
The body of the message looks like the following:
SerialNumber=P01238710163241048,IP=192.168.0.1,NetMask=255.255.255.0,Gateway=0.0.0.0
The packet must be sent using the broadcast address of 255.255.255.255.
Note: Not all the switches are
configured to pass broadcast packets by default. A switch
configuration change may be necessary to enable the passing of broadcast packets.
2. Upon receipt of the broadcast message the device verifies that the message is addressed to it by comparing
Protocol ID
field to value 0x6956752b, “iVu+”.
• If the value matches, the device examines the Message Type field.
• If the Message Type field matches 0x53455449, “SETI”, the received SerialNumber is compared with the
SerialNumber of the device.
• If the received serial number does not match, the packet is discarded and no further replies or logs are
generated.
• If the received serial number matches that of the device, the device performs the following actions:
◦ IP, NetMask, and Gateway addresses are extracted from the body of the message.
◦ Values are
verified to be syntactically correct.
▪ For example, Gateway address of 255.255.255.255 is not allowed
▪ IP address of 0.0.0.0 or 255.255.255.255 is not allowed
▪ The check for duplicate IP address will not be performed
◦ If the values do not pass the syntax check:
▪ The packet is discarded.
▪ The failed attempt is logged in the System Log.
▪ A DISCOVER_REPLY (RPLY) reply with current values is generated and sent (see
Discovery
of a Device
(p. 96) for details).
◦ If the values pass the syntax check:
▪ The new values are stored in the device.
▪ The change is logged in the System Log.
▪ A DISCOVER_REPLY (“RPLY) reply with new values is generated and sent (see
Discovery of
a Device
(p. 96) for details).
▪ The device restarts.
