Re: 3750G

Shahid,

Yes i have a L3 interface in which i would be doing ingress policing. so in
case i need to police at 250 mb on a 1 gig link. what would be the formula.
is the same formula posted on cisco website

normal burst = configured rate * (1 byte)/(8 bits) * 1.5 seconds

extended burst = 2 * normal burst

also can you share your configuration and what do you think will 3750G
be able to police at 250 mb.

thanks
naman
