If the interface is a member of a VLAN, you may specify the VLAN for whichingress packets are policed.Figure 41-4. Rate Policing Ingress TrafficFigure 41-5. Displaying your Rate Policing ConfigurationFTOS Behavior: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-limitvalue. 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 onwhich the dot.1p priority is changed on incoming traffic using the dot1p-priority commandFTOS#config tFTOS(conf)#interface gigabitethernet 1/0FTOS(conf-if)#rate police 100 40 peak 150 50FTOS(conf-if)#endFTOS#FTOS#show interfaces gigabitEthernet 1/2 rate policeRate police 300 (50) peak 800 (50)Traffic Monitor 0: normal 300 (50) peak 800 (50)Out of profile yellow 23386960 red 320605113Traffic Monitor 1: normal NA peak NAOut of profile yellow 0 red 0Traffic Monitor 2: normal NA peak NAOut of profile yellow 0 red 0Traffic Monitor 3: normal NA peak NAOut of profile yellow 0 red 0Traffic Monitor 4: normal NA peak NAOut of profile yellow 0 red 0
