Hi,


You can configure Policing or Shaping whatever method you want to use at the SVI (The Vlan Interface itself) and limit ur bandwidth accordingly.

Hi,


here is a (Policing) example, assumed u are limiting the bandwidth at vlan 10 interface to 256Kbps:-


class-map match-any vlan10

match access-group 100


access-list 100 permit ip any any


policy-map vlan10 (Rate limited at 256Kbps)

class vlan10

police 256000000 32000 action transmit exceed action drop


int vlan 10

service-policy output vlan10

Is the police command correct? Should it not be:


police 256000 32000 action transmit exceed action drop

Yes , you are right...


I think I have misatkenly typed it with extra 3 Zeros. Hence it in Bps , so it should be 256000.
