Figure 23. Packet Simulation Options Dialog Box (IXP2400 and IXP2800) - Traffic Interface
Logging
If there is more than one chip in your system configuration, select the chip for which you want to
specify Traffic Interface Logging:
There are three general options available:
•
Select or clear Enable Logging to toggle whether packet logging occurs or not. This is a
global setting which determines whether the individual logging settings are in effect.
•
Select or clear Log frame numbers to toggle whether or not frame numbers are logged along
with the packet data. If enabled, the frame number appears as the first item on a line. Frame
numbering starts when debugging is started, with the first packet received on a port and first
packet transmitted to a port being number 1. The numbers continue to increment regardless of
whether logging is enabled or not. So if you enable logging, disable it, then enable it again you
will see a gap in the logged frame numbers.
•
Select or clear Log media bus cycle times for SOP and EOP to toggle whether or not to log
the cycle times at which the first byte and last byte of a packet are received or transmitted. If
enabled, the cycles times appear before the packet data on the line but after the frame number,
if Log frame numbers is also selected.
If logging of both frame numbers and cycle times are enabled, the logged data looks like:
