Auto-negotiate Check if you want the port and end-device to
auto-negotiate the link speed and duplex mode.
Clear the check box to manually select the desired port
speed and duplex mode.
We recommend that you use the default
(auto-negotiate) so that the speed and duplex
settings on the switch port automatically match the
setting on the connected device. Change the switch
port speed and duplex if the connected device
requires a specific speed and duplex. If you set the
speed and duplex for the switch port, the
connected device must also be configured for the
exact same speed and duplex, and not set to
auto-negotiate, otherwise a speed/duplex
mismatch will occur.
Fiber optic interfaces do not support
auto-negotiation.
Speed Gigabit (Gi):
• 10 Mbps
• 100 Mbps
• 1 Gbps
Fast Ethernet (Fa)
• 10 Mbps

Choose the operating speed of the port.
Duplex • Half-duplex – Both devices cannot send data at the
same time.
Half-duplex is not available when speed is set to 1
Gbps.
• Full-duplex – Both devices can send data at the same
time.
Choose the duplex mode of the port.
