Description
10-Gigabit CX4 Copper Ports:
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, flow control is not used. Note that flow control must be enabled on both
ends of a link.
Broadcast limit
Specifies the percentage of the theoretical maximum network bandwidth that can be used
for broadcast traffic. Any broadcast 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.
