[cisco-voip] QoS on a 2960

[O'Brien, Neil]

Hi Brian,

Thanks for the reply.  But am I right in thinking it's aggressively policing the voip traffic to 1Mb/s.  I would assume that someone's voice traffic wouldn't go anywhere near 1Mb/s so then it's a COS spoofing prevention measure?

Regards,

That got introduced in newer code, 12.2(44)SE I think, for all 2960, 3560, etc.
