Configure Port-based Rate Shaping

Configure Port-based Rate Limiting
FTOS Behavior: On the C-Series and S-Series, rate shaping is effectively rate limiting because of its smaller
buffer size. On the S4810, rate shaping on tagged ports is slightly greater than the configured rate and rate shaping
on untagged ports is slightly less than configured rate.
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 buf f er space
that is allocated to the port.
• Apply rate shaping to outgoing traffic on a port using the command
mode, as shown in
• Apply rate shaping to a queue using the command
