Configuring basic port parameters

• 10-half – 10 Mbps, half duplex
• 100-full – 100 Mbps, full duplex
• 100-half – 100 Mbps, half duplex
• 1000 – 1 Gbps, full duplex (supported on PowerConnect B-Series TI24X 10-GbE ports only)
• 1000-full-master – 1 Gbps, full duplex master (not supported on the PowerConnect B-Series
TI24X)
• 1000-full-slave – 1 Gbps, full duplex slave (not supported on the PowerConnect B-Series TI24X)
• 10000 – 10 Gbps, full duplex (supported on PowerConnect B-Series TI24X 10-GbE ports only)
• auto – auto-negotiation
The default for copper ports is auto (auto-negotiation).
The default for fiber ports on the PowerConnect B-Series TI24X is 10000 (10 Gbps, full duplex).
Use the no form of the command to restore the default.
NOTE
On PowerConnect B-Series TI24X devices, when 10/100/1000 copper ports (ports 25 – 28)
auto-negotiate to either 1 Gbps or 100 Mbps, the green and amber LEDs will be lit solid (ON) when
the link is up, and the amber LED will blink when traffic flows through the port. On PowerConnect
B-Series TI24X devices, if the speed is set to Auto for a 1G port, the port auto-negotiates the flow
control with the neighboring port.
Auto speed detect
On PowerConnect B-Series TI24X devices, if you insert a 1G SFP, the device detects the media
change and automatically change the speed to support 1G for that port. This happens when the
configured speed is 10G. The configured speed continues to be 10G, but the port comes up with
operational speed of 1G. This removes the need for explicitly configuring speed-duplex 1000 for
SFPs where the device is able to detect the media type.
NOTE
All the ports with 1G SFPs which need to form a trunk (static or dynamic), need to use either the Auto
speed detect feature to come up in 1G mode or use the speed-duplex 1000 command. Configuring
speed-duplex 1000 on only few of the ports to be part of the trunk will prevent trunk creation.
Modifying port duplex mode
You can manually configure a 10/100 Mbps port to accept either full-duplex (bi-directional) or
half-duplex (uni-directional) traffic.
NOTE
You can modify the port duplex mode of copper ports only. This feature does not apply to fiber ports.
Port duplex mode and port speed are modified by the same command.
Configuration syntax
To change the port speed of interface 8 from the default of 10/100/1000 auto-sense to 10 Mbps
operating at full-duplex, enter the following.
