FLOWCONTROL
25-7
manually specify the link attributes with the speed-duplex and
flowcontrol commands.
Example
The following example configures Ethernet port 5 capabilities to include
100half and 100full.
Related Commands
negotiation (25-5)
speed-duplex (25-3)
flowcontrol (25-7)
flowcontrol
This command enables flow control. Use the no form to disable flow
control.
Syntax
[no] flowcontrol
Default Setting
Disabled
Command Mode
Interface Configuration (Ethernet - Ports 17-19, Port Channel)
Command Usage
1000BASE-T does not support forced mode. Auto-negotiation
should always be used to establish a connection over any
1000BASE-T port or trunk.
Flow control can eliminate frame loss by “blocking” traffic from end
stations or segments connected directly to the s witch when its buffers
fill. When enabled, back pressure is used for half-duplex operation and
IEEE 802.3-2002 (formally IEEE 802.3x) for full-duplex operation.
