If port C8 was disabled, and you wanted to enable it and configure it for
100FDx with flow-control active, you could do so with either of the following
command sets.
Refer to "Enabling or Disabling Flow Control" on page 10-12 for more on flow
control.

Enabling or Disabling Flow Control

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 10-8.) 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
Enables or disables flow control packets on the port. The "no"
form of the command disables flow control on the individual
ports. (Default: Disabled.)
For example, suppose that:
1. You want to enable flow control on ports A1-A6.
2. Later, you decide to disable flow control on ports A5 and A6.
3. As a final step, you want to disable flow control on all ports.
These commands enable and configure
port C8 from the config level:
These commands select the port C8
context level and then apply the
subsequent configuration commands
to port C8:
