atmspeed(1M)

NAME

atmspeed − get and set the total link bandwidth of an ATM device

SYNOPSIS

/opt/SUNWatm/bin/atmspeed interface [ bandwidth ]

AVAILABILITY

SUNWatmu

DESCRIPTION

atmspeed gets and sets the link bandwidth (wire speed) of an ATM device, providing a mechanism to limit the total bandwidth of the ATM device. If no bandwidth is specified, the current link bandwidth is displayed in Megabits per second. If a bandwidth is specified, the link bandwidth is set to that amount; the total throughput of the link will be limited to the value specified. The specified bandwidth should be an integer number of Megabits per second, and should be less than the maximum bandwidth that may be allocated, which is 135 Mbits/sec in the SunATM 1.0 and 2.0 products. See the ATM device man pages (ba(7) and sa(7)) for information on the maximum device bandwidth.

EXAMPLES

The following example shows how the bandwidth of an ATM device may be limited for a switch that can only handle 100 Mbits/sec of traffic. After being set, the idle bandwidth is checked to verify the correct setting.
