Enabling or Disabling Flow Control

N o t e
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 10-3 on page 10-9.) Also, the port (speed-duplex)
mode must be set to Auto (the default).
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 ]interface < port-list > flow-control
For example, suppose that:
1.
2.
Assuming that flow control is currently disabled on the switch, you would use
these commands:
Enables or disables flow control packets on the port. The "no"
form of the command disables flow control on the individual
ports. (Default: Disabled.)
You want to enable flow control on ports 5-6.
Later you want to disable flow control on those ports.
