Parameter

Definition

 

 

Name

A user-assigned name for this port (possibly a

 

drop name or the name of the station or other

 

device connected to the port).

 

 

Category

Allows you to select either User Port or Service

 

Port.

 

• The User Port is intended for use with

 

switch connections to end user nodes.

 

• The Service Port is intended for use with

 

switch connections to servers or other

 

switches. The Service Port allows the switch

 

to generate both log messages and alarm

 

messages (traps). The User Port only generates

 

log messages, preventing your network

 

management station from being

 

overwhelmed by port up/down messages

 

that result from users turning workstations

 

on and off.

 

 

Speed Mode

Allows you to select the speed of the port

 

manually (to either 10 or 100 Mb/s). If auto-

 

negotiation is enabled, this setting is

 

ignored.

 

 

Duplex Mode

Allows you set the port duplex mode (half- or

 

full-duplex).If auto-negotiation is enabled,

 

this setting is ignored.
