We have noticed in that icmp echo-replies and traceroutes that hit the real ip (rip) of the SVI on our 4506 supervisor have unusually high response times, but traces and pings through the switch respond with normal/expected latency values.
It is my understanding that the Supervisor IV engine places a lower value on processing packets to an svi than it does through the svi, but I need some documentation confirming this to appease our delvelopers, or any other solutions that may eliminate this delay.
Appreciate in advance any relevant responses.
Thanks,
