Configures the Committed Information Rate (CIR) and Committed Burst Size (CBS) for IPv4 and IPv6 subnet trap frames.
By default, CIR and CBS are not configured.
Control plane configuration mode
The CIR is the maximum number of bits that a port can receive or send during a one-second interval. The rate of the traffic that matches the traffic policing policy cannot exceed the CIR. The CIR represents a portion of interface bandwidth, expressed in bits per second (bps), and it cannot exceed port bandwidth. CIR-defined traffic that does not use the available CIR accumulates credit up to the amount defined by the CBS. This credit is the number of bytes that can be used to accommodate temporary bursts in traffic that exceed the CIR.
(SLX 9150 and SLX 9250) By default, IPv4 and IPv6 subnet trap frames are diverted to a separate queue (queue number 9). You can use the ip subnet-rate-limit command to further limit the rate of IPv6 subnet trap frames .
(SLX 9540 and SLX 9640) By default, IPv4 and IPv6 subnet trap frames are rate-limited to 10,000 Kbps. You can use the ip subnet-rate-limit command to further limit IPv4 and IPv6 subnet trap frames.
The following example configures the CIR to 134 Kbps and the CBS to 34 KB.
