There is no useful data to be gotten from polling. In addition, the fact that TRAPS are proactive instead of reactive means I have am immediately aware of network events whereas I might miss something with a poll. In addition, we have dry contact closures on these devices that TRAP only, no polling. Thankfully, the number of these events is small enough that syslog functions quite well. Syslog has not been up to the task of working with the sheer volume of TRAPS generated when there is a significant event on the optical network. Sometimes we see the notification but not the resolution, sometimes we see all but the last line of a TRAP message, and sometimes we get nothing.
