4-191
Command Usage
When auto-negotiation is enabled with the
negotiation
command, the
switch will negotiate the best settings for a link based on the
capabilites
command. When auto-negotiation is disabled, you must manually specify
the link attributes with the
speed-duplex
and
flowcontrol
commands.
Example
The following example configures Ethernet port 5 capabilities to 100half and
100full.
Related Commands

This command enables flow control. Use the
no
form to disable flow
control.

Command Usage
• Flow control can eliminate frame loss by “blocking” traffic from end
stations or segments connected directly to the switch when its buffers
fill. When enabled, back pressure is used for half-duplex operation and
IEEE 802.3x for full-duplex operation.
Console(config)#interface ethernet 1/5
Console(config-if)#capabilities 100half
Console(config-if)#capabilities 100full

30. There are interoperability problems between Flow Control and Head-of-Line (HOL) blocking for the
switch ASIC; Flow Control is therefore not supported for this switch.
