
NTP Server: The IP address or domain name of an NTP (Network Time Protocol) server
from which the switch may retrieve the current time at startup. Please note that using a
domain name requires that at least one domain name server be configured.
3.1.6 Configuring the Ethernet Ports
The switch comes with default port settings that should allow you to connect to the Ethernet
Ports with out any necessary configuration. Should there be a need to change the name of
the ports, negotiation settings or flow control settings, you can do this in the Port Configura-
tion menu. Access this menu by selecting Setup from the Main menu, and then selecting
Main Settings.

Port Name: Each port in the managed switch can be identified with a custom name.
Specify a name for each port here.

Admin: Ports can be enabled or disabled in the managed switch. For ports that are dis-
abled, they are virtually non-existent (not visible in terms of switch operation or spanning
tree algorithm). Choose to enable or disable a port by selecting Enabled or Disabled,
respectively.

Negotiation: All copper ports and gigabit fiber ports in the managed switch are capable
of autonegotiation such that the fastest bandwidth is selected. Choose to enable auto-
negotiation or use fixed settings. 100Mbps Fiber ports are Fixed speed only.

Speed/Duplex/Flow Control: The managed switch accepts three local area network
Ethernet Standards. The first standard, 10BASE-T, runs 10Mbps with twisted pair Ether-
net cable between network interfaces. The second local area network standard is
100BASE-T, which runs at 100Mbps over the same twisted pair Ethernet cable. Lastly,
there is 100BASE-F, which enables fast Ethernet (100Mbps) over fiber.
These options are available:

10h–10 Mbps, Half Duplex

10f –10 Mbps, Full Duplex

100h–100 Mbps, Half Duplex

100f –100 Mbps, Full Duplex

1000f–1000 Mbps, Full Duplex
On managed switches with gigabit combination ports, those ports with have two rows, a
standard row of check boxes and a row labeled “SFP” with radio buttons. The SFP setting
independently sets the speed at which a transceiver will operate if one is plugged in. Other-
wise, the switch will use the fixed Ethernet port and the corresponding settings for it.
3.2. Command Line Interface Configuration
3.2.1 Introduction to Command-Line Interface (CLI)
The command-line interface (CLI) is constructed with an eye toward automation of CLI-
based configuration. The interaction is modeled on that used in many Internet protocols
When 100f is selected for the SFP of a gigabit combination port, the corresponding
fixed Ethernet jack will be disabled unless it is changed back to 1000F.
