Description
The target rate limiting feature is used to minimize congestion at the HBA port due to a slow drain
device operating in the fabric at a slower speed. A remote port’s operating speed is determined
from the fabric. Traffic destined to the remote port is limited to its current operating speed.
The default rate limit is 1 Gbps. Target rate limiting (TRL) is supported only when the HBA port is
connected to the fabric. Therefore, TRL is not supported when the port is directly connected with
another device.
NOTE
You must first enter the bcu port -disable <port_id> command, followed by the port - -enable
command, before the ratelim - -enable or ratelim - -disable commands take effect.
Operands
--enable
Enables target rate limiting.
port_id
Specifies the ID of the port you want to enable.
--disable
Disables target rate limiting on the HBA.
port_id
Specifies the ID of the port you want to disable.
--query
Queries the target rate limiting details.
port_id
Specifies the ID of the port for which you want to display information.
--defspeed
Sets the default target rate limiting speed. The default TRL speed must be
supported and less than the maximum speed at which the card can operate.
port_id
Specifies the ID of the port on which you want to set the speed.
speed 1|2|4
Sets the default target rate limiting speed on the HBA. Options are 1 Gbps, 2
Gbps, and 4 Gbps
