To enable flow control using ACLI, see the following sections:
• flowcontrol command on page 146
• no flowcontrol command on page 146
• default flowcontrol command on page 147
flowcontrol command
Use the flowcontrol command only on Gigabit Ethernet ports to control the traffic rates
during congestion.
The syntax for the
flowcontrol command is
flowcontrol [port <portlist>] {asymmetric | symmetric | auto |
disable}
Run the flowcontrol command in Interface Configuration mode.
The following table describes the parameters for this command.
Table 61: Flowcontrol parameters
Parameters and
variables
Description
port <portlist> Specify the port numbers to configure for flow control.
Important:
If you omit this parameter, the system uses the ports you
specified
in the interface command but only those ports
that have speed set to 1000/full.
asymmetric | symmetric |
auto | disable
Set the mode for flow control:
• asymmetric: P
AUSE frames can flow only in one direction.
• symmetric: PAUSE frames can flow in either direction.
• auto: Set the port to automatically determine the flow control
mode (default).
• disable: Disable flow control on the port.
no flowcontrol command
Use the no flowcontrol command only on Gigabit Ethernet ports to disable flow control.
The syntax for the no flowcontrol command is
no flowcontrol [port <portlist>]
