Thinklogical Router Interfaces - Manual (Page 6)

Network
The router will use up to three IP addresses. The primary CPU card will use address X and address
X+100. The back-up CPU will use address X+1 and it will take over address X in the event of a failure in
the primary CPU.
The factory default value for 'X' is 192.168.13.15. Steps for changing the IP address are described in the
router manual: VX40_160_320_320V_Manual_Rev_*.pdf.
The router has several network ports reserved for internal use. Port 17567 accepts commands to control
the switch. The command API is described in the manual: VxRouter-ASCII-API.pdf.
There are several other ports that can be read to access system configuration and operating data. The
actual data format varies by model and is described in the next sections. There are five blocks of data
available for reading.
1. Switch connection status (broadcast over port 17564 every few seconds)
• The primary CPU IP address
• Upper or Lower chassis flag
• First port number in this block
• Last port number in this block
• 'N' port number values
2. Port settings (UDP port 17565, router localhost only)
• Port output level value
• Port input enable status
• Input port number (big-endian format)
3. Hardware sensor status (TCP port 17566)
• This is the text output from the lm_sensors 'sensors' command and is reserved for future
use.
4. Alarm, Inventory and Power Supply Status (TCP port 17600)
• State of the alarm contacts
• Card Inventory
• Reset Bits
• Power Supply Status
5. I/O card data (TCP ports 17601 through 17640, 1 port per I/O card)
• SFP TxDisable & TxFault bits
• SFP installed flag
• I/O card type
• SFP serial ID data
• SFP Diagnostic data
Switch connection status is broadcast over the network every 4 seconds. The information in the data block
is not sufficient to identify the model of the router. You should use the IP address in the data to identify
which router sent the message.
