Enabling or Disabling Flow Control

3400cl/6400cl Switches: Flow-Control on these switches is enabled and
■
disabled on a per-port basis.
■ 5300xl Switches: You must first enable flow-control globally on the
switch, and then enable it on the desired ports.
You must enable flow control on both ports in a given link. Otherwise, flow
control does not operate on the link, and appears as Off in the show interfaces
brief port listing, even if flow control is configured as enabled on the port in
the switch. (Refer to figure 10-4 on page 10-9.) Also, the port (speed-duplex)
mode must be set to Auto (the default).
Flow Control on the 3400cl/6400cl Switches.
Syntax: [ no ] interface < port-list > flow-control
Enables or disables flow control packets on < port-list > ports.
The "no" form of the command disables flow control. (Default:
Disabled.)
Use the show interfaces brief command (figure 10-4 on page 10-9)
to view the current per-port flow-control configuration.
Flow Control on the 5300xl Switches. As mentioned earlier, flow control
operates on individual 5300xl switch ports after you first enable global flow
control and then per-port flow control. The reverse is true for disabling flow
control on all ports. (Disable per-port flow control, and then disable global
flow control.) To disable flow control on some ports, while leaving it enabled
on other ports, just disable it on the individual ports you want to exclude.
Syntax: [ no ] flow-control
Enables or disables flow-control globally on the switch, and is
required before you can enable flow control on specific ports.
To use the no form of the command to disable global flow-
control, you must first disable flow-control on all ports on the
switch. (Default: Disabled)
[ no ] interface < port-list > flow-control
Enables or disables flow control packets on the port. The "no"
form of the command disables flow control on the individual
ports. (Default: Disabled.)
