Configuring Ieee 802.3X Flow Control - Cisco WS-X6066-SLB-APC - Content Switching Module Software Manual

Setting the Port Configuration
This example shows how to set the duplex mode to half duplex on port 2/1:
Console> (enable) set port duplex 2/1 half
Port 2/1 set to half-duplex.
Console> (enable)

Configuring IEEE 802.3X Flow Control

Gigabit Ethernet ports on the Catalyst 6000 family switches use flow control to inhibit the transmission
of packets to the port for a period of time; other Ethernet ports use flow control to respond to
flow-control requests.
If a Gigabit Ethernet port receive buffer becomes full, the port transmits a "pause" packet that tells
remote ports to delay sending more packets for a specified period of time. All Ethernet ports
(1000 Mbps, 100 Mbps, and 10 Mbps) can receive and act upon "pause" packets from other devices.
Enter the set port flow control command to configure flow control on ports.

To configure flow control, perform this task in privileged mode:
Task
Step 1
Set the flow-control parameters.
Step 2
Verify the flow-control configuration.
This example shows how to turn transmit and receive flow control on and how to verify the flow-control
configuration:
Console> (enable) set port flowcontrol 3/1 send on
Port 3/1 will send flowcontrol to far end.
Console> (enable) set port flowcontrol 3/1 receive on
Port 3/1 will require far end to send flow control

Ethernet-Flow Control Keyword Functions
Function
The port uses flow control dictated by the neighboring port.
The port uses flow control if the neighboring port uses it and does not
use flow control if the neighboring port does not use it.
The port does not use flow control, regardless of whether flow control is
requested by the neighboring port.
1
The port sends flow-control frames to the neighboring port.
1
The port sends flow-control frames to the port if the neighboring port
asks to use flow control.
1
The port does not send flow-control frames to the neighboring port.
