Negotiation - SMC Networks 8126PL2-F - annexe 1 Management Manual

Default Setting
• Auto-negotiation is enabled by default.
• When auto-negotiation is disabled, the default speed-duplex setting is 100half
for 100BASE-TX ports and 1000full for Gigabit Ethernet ports.
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
• The 1000BASE-T standard does not support forced mode. Auto-negotiation
should always be used to establish a connection over any 1000BASE-T port
or trunk. If not used, the success of the link process cannot be guaranteed
when connecting to other types of switches.
• To force operation to the speed and duplex mode specified in a speed-duplex
command, use the no negotiation command to disable auto-negotiation on
the selected interface.
• When using the negotiation command to enable auto-negotiation, the
optimal settings will be determined by the capabilities command. To set the
speed/duplex mode under auto-negotiation, the required mode must be
specified in the capabilities list for an interface.
Example
The following example configures port 5 to 100 Mbps, half-duplex operation.
Console(config)#interface ethernet 1/5
Console(config-if)#speed-duplex 100half
Console(config-if)#no negotiation
Console(config-if)#
