Description

For ATM 2 PICs only, define the real-time variable bandwidth utilization in the traffic-shaping profile.

When you configure the real-time bandwidth utilization, you must specify all three options (burst, peak, and sustained). You can specify rate in bits per second either as a complete decimal number or as a decimal number followed by the abbreviation k (1000), m (1,000,000), or g (1,000,000,000). You can also specify rate in cells per second by entering a decimal number followed by the abbreviation c; values expressed in cells per second are converted to bits per second using the formula 1 cps = 384 bps.

Default

Unspecified bit rate (UBR); that is, bandwidth utilization is unlimited.

Options

burst length—Burst length, in cells. If you set the length to 1, the peak traffic rate is used.
Range: 1 through 4000 cells

peak rate—Peak rate, in bps or cps.
Range: 33 kbps through 135.6 Mbps (ATM OC-3); 33 kbps through 276 Mbps (ATM OC-12)

sustained rate—Sustained rate, in bps or cps.
Range: 33 kbps through 135.6 Mbps (ATM OC-3); 33 kbps through 276 Mbps (ATM OC-12)
