Gigabit Fiber-Optic Ports (Gigabit-SX, Gigabit-LX, and Gigabit-LH):
• 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.
Gigabit Copper Ports:
• 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.
10-Gigabit CX4 Copper Ports:
• Auto : The port operates at 10 gigabits FDx and negotiates flow control. Lower speed settings or half-
duplex are not allowed.
10-Gigabit SC Fiber-Optic Ports (10-GbE SR, 10-GbE LR, 10-GbE ER):
• Auto : The port operates at 10 gigabits FDx and negotiates flow control. Lower speed settings or half-
duplex are not allowed.
Note: Conditioning patch cord cables are not supported on 10-GbE.
Auto-MDIX The switch supports Auto-MDIX on 10Mb, 100Mb, and 1 Gb T/TX (copper) ports. (Fiber ports and 10­
gigabit ports do not use this feature.)
•
Automdix: Configures the port for automatic detection of the cable type (straight-through or
crossover).
• MDI: Configures the port to connect to a switch, hub, or other MDI-X device with a straight-through
cable.
• MDIX: Configures the port to connect to a PC or other MDI device with a straight-through cable.
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. Note that flow control must be enabled on both ends of a link.
Broadcast Specifies the percentage of the theoretical maximum network bandwidth that can be used for broadcast
Limit and multicast traffic. Any broadcast or multicast traffic exceeding that limit will be dropped. Zero (0)
means the feature is disabled.
The broadcast-limit command operates at the port context level to set the broadcast limit for a port on
the switch.
Note: This feature is not appropriate for networks that require high levels of IPX or RIP broadcast traffic.
