config ports
Purpose
Used to configure the Switch’s Ethernet port settings.
Syntax
[<portlist> | all ] {medium_type [fiber | copper]} {speed [auto {capability_advertised
{10_half | 10_full | 100_half | 100_full | 1000_full} (1) } | 10_half | 10_full | 100_half |
100_full | 1000_full { [master | slave] } ] | auto_negotiation restart_an | flow_control
[enable | disable] | learning [enable | disable ] | state [enable | disable] | [description
<desc 1-32> | clear_description]} (1)
Description
This command allows for the configuration of the Switch’s Ethernet ports. Only the ports
listed in the
<portlist>
will be affected.
Parameters
all
−
Configure all ports on the Switch.
<portlist>
−
Specifies a port or range of ports to be configured. The port list is specified by
listing the lowest switch number and the beginning port number on that switch, separated
by a colon. Then the highest switch number, and the highest port number of the range
(also separated by a colon) are specified. The beginning and end of the port list range are
separated by a dash. For example, 1:3 specifies switch number 1, port 3. 2:4 specifies
switch number 2, port 4. 1:3–2:4 specifies all of the ports between switch 1, port 3 and
switch 2, port 4
−
in numerical order. Non–contiguous portlist entries are separated by a
comma. (ex: 1:1–1:3,1:7–1:9)
medium_type [fiber | copper]
– This applies only to the Combo ports. If configuring the
Combo ports this defines the type of transport medium used.
speed
– Allows the user to adjust the speed for a port or range of ports. The user has a
choice of the following:
•
auto
−
Enables auto–negotiation for the specified range of ports.
•
capability advertised
– Configures the capability that advertises to the link partner
to determine the fastest available auto setting.
•
[10 | 100 | 1000]
−
Configures the speed in Mbps for the specified range of ports.
Gigabit ports are statically set to 1000 and cannot be set to slower speeds.
•
[half | full]
−
Configures the specified range of ports as either full–duplex or half–
duplex.
•
[master | slave]
– The master setting (1000M/Full_M) will allow the port to
advertise capabilities related to duplex, speed and physical layer type. The
master setting will also determine the master and slave relationship between the
two connected physical layers. This relationship is necessary for establishing the
timing control between the two physical layers. The timing control is set on a
master physical layer by a local source. The slave setting (1000M/Full_S) uses
loop timing, where the timing comes form a data stream received from the
master. If one connection is set for 1000M/Full_M, the other side of the
connection must be set for 1000M/Full_S. Any other configuration will result in a
link down status for both ports.
