Configuring Port Traffic Rate Limiting

Purpose
To limit the rate of inbound traffic on the SecureStack C2 device on a per port/priority basis. The
allowable range for the rate limiting is 64 kilobytes per second minimum up to the maximum
transmission rate allowable on the interface type.
Rate limit is configured for a given port and list of priorities. The list of priorities can include one,
some, or all of the eight 802.1p priority levels. Once configured, the rate of all traffic entering the
port with the priorities configured to that port is not allowed to exceed the programmed limit. If
the rate exceeds the programmed limit, frames are dropped until the rate falls below the limit.
Clears transmit queue values on specific port(s) back to their default
values. For a detailed description of possible port‐string values, refer to
"Port String Syntax Used in the CLI" on page 5‐2.
Only physical ports can be configured with this command. LAG ports
cannot be configured.
