Oh, yes it will. It still takes CPU cycles to process the information and
generate the necessary SNMP packets. If you're hammering the CPU once every
millisecond to do this, it isn't going to have much time for anything else.
Sorry but packet forwarding is done in hardware , basically during normal
operation a switch cpu utilisation is virtually zero. The CPU is only used
during the startup phase of the switch (during STP), andother particular
moments.
That is true for established flows but isn't any new flow first sent to
the CPU and then "programmed" into hardware? So isn't "hammering" the
CPU the same as "hammering" intial flow setup? (On a busy network the
number of flow setup requests to the cpu is not insignificant).
