Example
XSR(config-if
duplex
This command, used in conjunction with the
speed
command, forces the FastEthernet/
GigabitEthernet interface to operate at a specific duplex mode and speed. Setting the speed or
duplex to auto‐negotiate implies that both the speed and the duplex mode will be negotiated. It is
not possible to manually set one and auto‐negotiate the other. For example, you cannot set the
speed to 10 Mb/s and set the duplex to auto‐negotiate.
When issuing this command, be aware of the following additional conditions:
•
Duplex mode cannot be changed while in loopback.
•
Changing the duplex mode preserves the speed.
•
When the speed is changed from
auto
, duplex will be set to
half
.
•
Setting speed or duplex to
auto
, no speed, or no duplex sets both duplex and speed to auto.
•
When connecting an
auto
setting on an XSR to a forced setting on another router, the forced
setting must be set to
half-duplex
regardless of the speed (10 or 100 Mbits).
•
When the Gigabit Fiber port is uses, both duplex and speed must be set to auto on both ends of
the line to avoid an unpredictable link.
Syntax
duplex {full | half | auto}
text
Alphanumeric characters which describe the interface.
full
Forces the interface to operate at full‐duplex.
half
Forces the interface to operate at half‐duplex.
auto
Allows the port to set the speed and duplex mode automatically.
