Re: Cisco ASR9902 SNMP polling ... is interesting

Sorry, Tom. I’m not taking the bait.

Mel-

You have made multiple technical assertions in this thread that are demonstrably false. Quoting your earlier messages :

  1.  Also, non-management interfaces do packet processing in silicon at the ASIC level and don’t have the capacity to 
do anything more than statistical sampling of packets that require CPU-level processing to retrieve counters and 
generate SNMP responses. 62 % is as good a sampling rate as any other.
  2.  Cisco is likely to say that the control plane is only fully supported on the management port.
  3.  In-band SNMP to data forwarding interfaces violates that separation.

 You have attempted to frame these comments as :

honest and sincere attempts by other members to help identify the possible problem.

While your attempts to help may have been honest and sincere attempts to help the OP, they actually achieved the 
opposite effect. Your incorrect technical assertions , if anything, only hindered the OP's attempt to understand and 
identify their issue. Comment #1 is especially egregious ; you're telling Drew that his observations are *normal*.

Saku made 2 comments that addressed these falsehoods :

It might be easier to contribute, if there is familiarity to the subject matter.

some community member piled on with what can only
be described as a bizarre drivel.

The first was a polite way of calling out the technical inaccuracies. The second was a more forceful way of stating 
"what you said was wrong". Most people, when they are corrected on a factual point, tend to reply with "Oh hey, I got 
that wrong, thanks for setting me straight" and move on. You seem to have just ignored it.

There is a massive difference between the following statements :

  1.  You are an idiot. [ Attacking the person ]
  2.  What you said was idiotic. [ Attacking the statements ]

It seems to be that you may be struggling in identifying that difference, and taking *any* criticism as a personal 
attack.

Nobody is bullying you, or anybody else, in this conversation.

Thanks. I knew we were not so out to lunch! If you don’t push back on bullies, they take over the community. It crops
