FTOS Configuration Guide for the C-Series - Force10 Networks

Configure Port-based Rate Limiting
Configure Port-based Rate Limiting is supported only on platform e
FTOS Behavior: On the C-Series and S-Series, rate shaping is effectively rate limiting because of its
smaller buffer size.
Rate limit egress traffic on an interface using the command rate limit from INTERFACE mode, as shown
in Figure 398. 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

Configure Port-based Rate Shaping
Rate shaping buffers, rather than drops, traffic exceeding the specified rate until the buffer is exhausted. If
any stream exceeds the configured bandwidth on a continuous basis, it can consume all of the buffer space
that is allocated to the port.
