Status or Description
Parameter
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.
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:
• Auto: The port operates at 10 gigabits FDx and negotiates flow control. Lower speed settings or half-
duplex are not allowed.
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 for connecting to a PC or other MDI device with a crossover cable.
• MDIX: Configures the port for connecting to a switch, hub, or other MDI-X 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. 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 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.
Series 5300xl Switches: The broadcast-limit command operates at the global configuration context
level to set the broadcast limit for all ports on the switch.
Series 3400cl and Series 6400cl Switches: The broadcast-limit command operates at the port context
level to set the broadcast limit on a per-port basis.
Note: This feature is not appropriate for networks that require high levels of IPX or RIP broadcast traffic.
