with the 802.3u standard, then the port configuration on the switch must be manually set
to match the port configuration on the other device.
Possible port setting combinations for copper ports are:
•
10HDx: 10 Mbps, Half-Duplex
•
10FDx: 10 Mbps, Full-Duplex
•
100HDx: 100 Mbps, Half-Duplex
•
100FDx: 100 Mbps, Full-Duplex
Possible port settings for 100FX (fiber) ports are:
•
100FDx (default): 100 Mbps, Full-Duplex
•
100HDx: 100 Mbps, Half-Duplex
Possible port settings for 10FL (fiber) ports are:
•
10HDx (default): 10 Mbps, Half-Duplex
•
10FDx: 10 Mbps, Full-Duplex
Gigabit fiber-optic ports
(Gigabit-SX and Gigabit-LX):
•
1000FDx (default): 1000 Mbps (1 GBPS), Full Duplex only
•
Auto
: The port operates at 1000FDx and auto-negotiates flow control with the
device connected to the port
Flow Control
Flow control is for full duplex operation and the controls provided indicates the number
of buffers allowed for incoming traffic before a Rxon or Rxoff information is sent. RXon
is sent when the number of buffers used by the traffic falls below the specified level
(default is 4). Rxoff is sent when the number of buffers used goes above the specified
value (default is 6). The "flowcontrol" command is used to set the above thresholds. It
DOES NOT enable or DISABLE flow control
Disabled
(default)
– The port will not generate flow control packets and drops received
flow control packets
Enabled
: The port uses 802.3x Link Layer Flow Control, generates flow control packets,
and processes received flow control packets.
With the port speed set to auto (the default) and flow control set to
enabled; the switch negotiates flow control on the indicated port. If the
port speed is not set to auto, or if flow control is disabled on the port,
then flow control is not used.
