VX320
17564 – Switch Connection Status Broadcast
• 32-bits, VxRouter's primary IP address
• 16-bits, 0 for the Upper (or only) VxRouter chassis
1 for the Lower VxRouter chassis
• 16-bits, first port number in the list (list starts from 1, not 0)
• 16-bits, last port number in the list
• N * 16-bits, the input port that is connected to output port X, zero means the port is NOT
connected
Example: c0 a8 0d 19 00 01 00 01 01 40 00 a0 01 40…
IP address = 192.168.13.25
Chassis = 1
First Port number = 1
Last Port number = 320 (
0x0140)
Output 1 is connected to input 160 ( 0x00a0)
Output 2 is connected to input 320 ( 0x0140)
The Vx320 consists of two chassis, so there will be two blocks transmitted; one for the
upper chassis and one for the lower.
17565 – Port Settings (localhost only)
320 sets of the following data:
• (8 bits)*2 output level 0 is off
• (8 bits)*2 input level
• (16 bits)*2 connected to input port number, starting from 0, big-endian format
The Vx320 consists of two chassis, so there are two entries for each piece of data. The first
is the value for the upper chassis and the second is for the lower chassis.
A 'C' data structure for this would be:
struct s_block {
unsigned char output_level[2];
unsigned char input_level[2];
unsigned short
connectedTo[2]; /* assumes short is 16 bits */
} data_block [320];
17566 – Hardware Status
Reserved for future use.
