100/1000Base-T ports:

• auto-mdix (default): Senses speed and negotiates with the port at the other end of the link for port

operation (MDI-X or MDI).

To see what the switch negotiates for the Auto setting, use the CLI show interfaces brief command

or the “3. Port Status” option under “1. Status and Counters” in the menu interface.

• mdi: Sets the port to connect with a PC using a crossover cable (Manual mode—applies only to copper

port switches using twisted-pair copper Ethernet cables)

• mdix: Sets the port to connect with a PC using a straight-through cable (Manual mode—applies only

to copper port switches using twisted-pair copper Ethernet cables)

• Auto-100: Uses 100 Mbps and negotiates with the port at the other end of the link for other port

operation features.

• Auto-1000: Uses 1000 Mbps and negotiates with the port at the other end of the link for other port

operation features.

• 100Hdx: Uses 100 Mbps, half-duplex.

• 100Fdx: Uses 100 Mbps, Full-Duplex

Notes:

• Changing the port speed on a transceiver port requires a reboot of the switch.

• Ensure that the device attached to the port is configured for the same setting that you select here.

Also, if “Auto” is used, the device to which the port connects must also be configured to “Auto” and

operate in compliance with the IEEE 802.3ab “Auto Negotiation” standard for 1000Base-T networks.

Gigabit fiber-optic ports (Gigabit-SX and Gigabit-LX):

• 1000FDx: 1000 Mbps (1 Gbps), Full Duplex only

• Auto (default): The port operates at 1000FDx and auto-negotiates flow control with the device

connected to the port.

Flow Control • Disabled (default): The port does not generate flow control packets, and drops any flow control

packets it receives.

• Enabled: The port uses 802.3x Link Layer Flow Control, generates flow control packets, and processes

received flow control packets.

With the port mode set to Auto (the default) and Flow Control enabled, the switch negotiates Flow Control

on the indicated port. If the port mode is not set to Auto, or if Flow Control is disabled on the port, then

Flow Control is not used. You must enable flow control globally on the switch before enabling it on

individual ports. Also, you must disable flow control on the individual ports before disabling it globally on

the switch. Note that flow control must be enabled on both ends of a link.

Broadcast Limits the bandwidth available for outbound broadcast traffic to 1000 packets per second for each port

Limit on the switch (regardless of packet size). Any outbound broadcast traffic overload will be dropped.

Note: This feature is not appropriate for networks that require high levels of IPX or RIP broadcast traffic.
