Packet Forwarding Commands

Description Shows the packet-forwarding settings for the line.
User Level Admin
Syntax

When the specified amount of time, in milliseconds, elapses after the first character is 

received from the serial port, the packet is transmitted. After a packet is transmitted, the 

next character received starts the timer again. A value of zero (0) ignores this 
parameter. Valid values are 0-65535 ms. The default is 0. 

Determines what is included in the Frame (based on the EOF1 or EOF1/EOF2) or 

Packet (based on Trigger1 or Trigger1/Trigger2). Choose one of the following options:

z

Strip-Trigger—Strips out the EOF1, EOF1/EOF2, Trigger1, or Trigger1/Trigger2, 
depending on your settings.

z

Trigger—Includes the EOF1, EOF1/EOF2, Trigger1, or Trigger1/Trigger2, 

depending on your settings.

z

Trigger+1—Includes the EOF1, EOF1/EOF2, Trigger1, or Trigger1/Trigger2, 

depending on your settings, plus the first byte that follows the trigger.

z

Trigger+2—Includes the EOF1, EOF1/EOF2, Trigger1, or Trigger1/Trigger2, 
depending on your settings, plus the next two bytes received after the trigger.

The amount of time, in milliseconds, that must elapse between characters before the 

packet is transmitted to the network. A value of zero (0) ignores this parameter. Valid 
values are 0-65535 ms. The default is 0. 

The number of byte that must be received from the serial port before the packet is 

transmitted to the network. A value of zero (0) ignores this parameter. Valid values are 

0-1024 bytes. The default is 0. 

When enabled, the Start of Frame character defines the first character of the frame, any 
character(s) received before the Start of Frame character is ignored. Valid values are in 

hex 0-FF. The default is 0.

When enabled, creates a sequence of characters that must be received to create the start 

of the frame (if the SOF1 character is not immediately followed by the SOF2 character, 
the IOLAN waits for another SOF1 character to start the SOF1/SOF2 character 

sequence). Valid values are in hex 0-FF. The default is 0.

When enabled, the SOF1 or SOF1/SOF2 characters will be transmitted with the frame. 

If not enabled, the SOF1 or SOF1/SOF2 characters will be stripped from the 
transmission.
