Configure Port-based Rate Limiting
Configure Port-based Rate Limiting is supported only on platform e
Rate limit egress traffic on an interface using the command rate limit from INTERFACE mode, as shown
in Figure 42-6. If the interface is a member of a VLAN, you may specify the VLAN for which egress
packets are rate limited.

Display how your rate limiting configuration affects traffic using the keyword rate limit with the command

Figure 42-7. Displaying How Your Rate Limiting Configuration Affects Traffic
FTOS 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-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
