Port Status and Basic Configuration

Viewing Port Status and Configuring Port Parameters

These commands enable and configure

port C8 from the config level:

This command enables flow control

globally on the switch (which is

required before you can enable flow

control on specific ports).

These commands select the port C8

context level and then apply the

subsequent configuration commands

to port C8:

Refer to “Enabling or Disabling Flow Control” on page 10-9 for more on flow

control.

Enabling or Disabling Flow Control. As mentioned earlier in this chap-

ter, flow control operates on individual 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.

Note 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 Series 5300XL switch. (Refer to figure

10-3 on page 10-7.) Also, the port

(speed-duplex) mode must be set to Auto (the default).

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.

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

these commands:
