Configure Port-based Rate Policing
Rate policing ingress traffic on an interface using the command rate police from INTERACE mode, as
shown in the example Rate Policing Ingress Traffic. If the interface is a member of a VLAN, you may
specify the VLAN for which ingress packets are policed.

FTOS Behavior:
Rate policing is supported only on physical port interfaces; it is not supported on port-channel and
VLAN interfaces.
On the C-Series and S-Series, rate shaping is effectively rate limiting because of its smaller buffer size.
On the E-Series:
— 802.1Q-priority tagged frames are sometimes not rate-limited according to the configured rate-limit
value. Only hybrid ports reliably apply the configured rate limit to priority-tagged frames
— Rate-limiting may not be applied according to the configured rate-limit value on an interface on
which the dot.1p priority is changed on incoming traffic using the dot1p-priority command
