Each command is listed, in detail, in the following sections. 
config ports 
Purpose 
Used to configure the Switch’s Ethernet port settings. 
Syntax 
[<portlist> | all] {medium_type [fiber | copper]}
 
{speed [auto | 10_half | 10_full | 100_half | 
100_full | 1000_full {[master | slave]}] | flow_control [enable | disable] | learning [enable | 
disable] | state [enable | disable] | [description <desc 1-32> | clear_description]} 
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.  
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. 
•  [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. 
flow_control [enable | disable] – Enable or disable flow control for the specified ports.  
learning [enable | disable] 
− Enables or disables the MAC address learning on the specified 
range of ports. 
state [enable | disable] 
− Enables or disables the specified range of ports.   
description <desc 32> - Enter an alphanumeric string of no more than 32 characters to describe 
a selected port interface. 
clear_description - Enter this command to clear the port description of the selected port(s). 
Restrictions Only 
administrator-level users can issue this command.
