• When using the negotiation command to enable auto-negotiation,

the optimal settings will be determined by the capabilities command.

To enable flow control under auto-negotiation, “flowcontrol” must

be included in the capabilities list for any port

• Avoid using flow control on a port connected to a hub unless it is

actually required to solve a problem. Otherwise back pressure

jamming signals may degrade overall performance for the segment

attached to the hub.

Example

The following example enables flow control on port 5.

combo-forced-mode

This command forces the port type selected for combination ports 21 - 24

or 45-48. Use the no form to restore the default mode.

Syntax

mode

•copper-forced - Always uses the built-in RJ-45 port.

•copper-preferred-auto - Uses the built-in RJ-45 port if both

combination types are functioning and the RJ-45 port has a

valid link.

•sfp-forced - Always uses the SFP port (even if a module is not

installed).

•sfp-preferred-auto - Uses SFP port if both combination types

are functioning and the SFP port has a valid link.
