The body of the message will look like this:
SerialNumber=P01238710163241048,Version=TB_v1.1.4,Name=Sensor1,MAC=00:11:22:33:44:
55,IP=192.168.0.1,NetMask=255.255.255.0,Gateway=0.0.0.0
•
The packet is broadcast on the network to port 19995. The sensor uses a pseudo-random
back-off time to minimize collisions with other sensors.
Change IP Address of a Sensor Using the MAC
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:
•
MAC (“MAC=00:11:22:33:44:55”)
•
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:
MAC=00:11:22:33:44:55,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 MAC address is compared with the MAC address of the sensor.
•
If the MAC address does not match, the packet is discarded
>No further replies or logs are generated
•
If the received MAC address 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
- 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
