Command: speed-duplex {auto | force10-half | force10-full | force100-half |
force100-full | { {force1g-half | force1g-full} [nonegotiate [master | slave]] } }
no speed-duplex
Function: Set the speed and duplex mode for 1000Base-TX or 100Base-TX ports; the
“no speed-duplex” command restores the default speed and duplex mode setting, i.e.
auto speed negotiation and duplex.
Parameter: auto for auto speed negotiation; force10-half for forced 10Mb/s at half
duplex; force10-full for forced 10Mb/s at full duplex mode; force100-half for forced
100Mb/s at half duplex mode; force100-full for forced 100Mb/s at full duplex mode;
force1g-half for forced 1000Mb/s at half duplex mode; force1g-full for forced 1000Mb/s
at full duplex mode; nonegotiate for disable auto negotiation for 1000 Mb port; master for
force the 1000 Mb port to be master mode; slave for force the 1000 Mb port to be slave
mode.
Command mode: Port configuration Mode.
Default: Auto negotiation for speed and duplex mode is set by default.
Usage Guide: This command applies to 1000Base-TX or 100Base-TX ports only.
speed-duplex command is not available for 1000Base-FX port. For combo port, this
command applies to the 1000Base-TX port only and has no effect on 1000Base-FX port.
To change the negotiation mode of 1000Base-FX port, use negotiation command
instead.
When configuring port speed and duplex mode, the speed and duplex mode must be the
same as the setting of the remote end, i.e. if the remote device is set to auto-negotiation,
then auto-negotiation should be set at the local port. If the remote end is in forced mode,
the same should be set in the local end.
1000Gb ports are defaulted to master when configuring nonegotiate mode. If one end is
set to master mode, the other end must be set to slave mode.
force1g-half Is not supported yet.
Example: Port 1 of Switch1 is connected to port 1 of Switch2, the following will set both
ports in forced 100Mb/s at half duplex mode.
Switch1(Config)#interface e1/1
Switch1(Config-Ethernet1/1)#speed-duplex force100-half
Switch2(Config)#interface e1/1
Switch2(Config-Ethernet1/1)#speed-duplex force100-half
