Port Status and Configuration

Viewing Port Status and Configuring Port Parameters

ProCurve(config)# int 8 enable ProCurve(config)# int 8 speed-duplex 100-full ProCurve(config)# int 8 flow-control

ProCurve(config)# int 8 ProCurve(eth-8)# enable ProCurve(eth-8)# speed-duplex 100-full

These commands enable and configure port 8 from the config level:

These commands select the port 8 context level and then apply the subsequent configuration commands to port 8:

Refer to “Enabling or Disabling Flow Control” on page 10-17for more on flow control.

	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 10-3on 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
	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 5-6.

2.Later you want to disable flow control on those ports.

Assuming that flow control is currently disabled on the switch, you would use these commands:
