- The check for duplicate IP address will not be performed
> If the values do not pass the syntax check, the packet is discarded
- The attempt is logged in the System Log
- A DISCOVER_REPLY (RPLY) reply with current values is generated and sent.
(please see Sensor Discovery for details)
> If the values do pass the syntax check:
- New values are stored in the sensor
- The change is logged in the System Log
A DISCOVER_REPLY (“RPLY) reply with new values is generated and sent.
(please see iVu Discovery Protocol Message Flow Discovery of a sensor
for
details)
- The sensor is restarted.
Change IP Address of a Sensor Using the Serial Number
1. PC broadcasts a DISCOVER_SETIP message
The header values are filled as follows:
• Protocol ID field must be set to 0x6956752b, “iVu+”
• Message Type field should be set to 0x53455449, “SETI”
• Correlation tag must be set by the sender to a non-zero value that will allow the originator to
identify the response
• The body of the message must be filled as follows:
• 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 will look like this:
SerialNumber=P01238710163241048,IP=192.168.0.1,NetMask=255.255.255.0,Gateway=0.0.0
.0
• The packet must be sent out 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 sensor performs the following:
Sensor verifies that the message is addressed to it by comparing Protocol ID field to value 0x6956752b, “iVu+”.
• If the value matches, the sensor examines the Message Type field
.
• If the Message Type field matches 0x53455449, “SETI”, the sensor performs the following
actions:
> The received SerialNumber is compared with the SerialNumber of the sensor.
- If the received serial number does not match, the packet is discarded
• No further replies or logs are generated
- If the received serial number matches that of the sensor, the sensor
performs the following actions:
• IP, NetMask, and Gateway addresses are extracted from the
body of the message
• Values are verified to be syntactically correct
