24-Port 10/100 + 2-Port Gigabit Switch with Webview and Power over Ethernet

Dynamic Address

The Dynamic Address Table contains the MAC addresses learned by monitoring the source address for traffic

entering the switch. When the destination address for inbound traffic is found in the database, the packets

intended for that address are forwarded directly to the associated port. Otherwise, the traffic is flooded to all

ports.

Interface

. Indicates a port or lag.

MAC Address

. Physical address associated with this interface.

VLAN

. ID of configured VLAN (1-4094).

Address Table Sort Key

. You can sort the information displayed based on MAC address, VLAN or interface (port

or lag).

Dynamic Address Counts

. The number of addresses dynamically learned.

Current Dynamic Address Table

. Lists all the dynamic addresses.

Specify the search type (that is, check the Interface, MAC Address, and/or VLAN checkbox), select the method of

sorting the displayed addresses, and then click

Query

.

Static address

A static address can be assigned to a specific interface on this switch. Static addresses are bound to the

assigned interface and will not be moved. When a static address is seen on another interface, the address will be

ignored and will not be written to the address table.

Static Address Counts

. The number of manually configured addresses. The Switch allows 8,000 Static Address

Counts.

Current Static Address Table

. Lists all the static addresses.

Interface

. Port or lag associated with the device assigned a static address.

MAC Address

. Physical address of a device mapped to this interface.

VLAN

. ID of configured VLAN (1-4094).

Specify the interface, the MAC address and VLAN, then click

Add Static Address

.

Time Synchronization

Simple Network Time Protocol (SNTP) allows the switch to set its internal clock based on periodic updates from a

time server (SNTP or NTP). Maintaining an accurate time on the switch enables the system log to record

meaningful dates and times for event entries. If the clock is not set, the switch will only record the time from the

factory default set at the last bootup. When the SNTP client is enabled, the switch periodically sends a request for

a time update to a configured time server. You can configure up to three time server IP addresses. The switch will

attempt to poll each server in the configured sequence.

The Time Synchronization screen displays the following information.

SNTP Client

. Configures the switch to operate as an SNTP client. This requires at least one time server to be

specified in the SNTP Server field. (Default: Disabled)

Current Time

. Displays the current time.

Name

. Assign a name for the time setting.

Hours

. Set the hours for the clock.

Minutes

. Set the minutes for the clock.

Direction

. SNTP uses Coordinated Universal Time (or UTC, formerly Greenwich Mean Time, or GMT) based on the

time at the Earth’s prime meridian, zero degrees longitude. To display a time corresponding to your local time,

you must indicate the number of hours and minutes your time zone is east (after) or west (before) of UTC.

Click the SNTP Client checkbox to Enable SNTP Client. Uncheck it to disable it.

Set the name, hours and minutes using the text fields.

Set the Direction by choosing the Before-UTC or After-UTC.

IP Config

24-Port 10/100 + 2-Port Gigabit Switch with Webview and Power over Ethernet

IP Config

The IP Config tab includes a link to the following screen.

•

IP Address

IP Address

To manually configure IP settings, you need to set an IP address and subnet mask that is compatible with your

network. You may also need to establish a default gateway between the switch and management stations that

exist on another network segment.

An IP address may be used for management access to the switch over your network. You may also need to

establish a default gateway between the switch and management stations that exist on another network

segment.

The IP Address screen displays the following information

IP Address Mode

. Specifies whether IP functionality is enabled via manual configuration (Static), Dynamic Host

Configuration Protocol (DHCP), or Boot Protocol (BOOTP). If DHCP/BOOTP is enabled, IP will not function until a

reply has been received from the server. Requests will be broadcast periodically by the switch for an IP address.

(DHCP/BOOTP values can include the IP address, subnet mask, and default gateway.)

Host Name

. Specifies the name of the switch. Enter the name into the textfield provided, up to 255 characters

long. (Default: None)

IP Address

. Address of the VLAN interface that is allowed management access. Valid IP addresses consist of four

numbers, 0 to 255, separated by periods. (Default: 192.168.1.254)

Mask

. This mask identifies the host address bits used for routing to specific subnets.

(Default: 255.255.255.0)

Default Gateway

. IP address of the gateway router between this device and management stations that exist on

other network segments. (Default: 0.0.0.0)

Current Management Interface

. ID of the configured VLAN (1-4094, no leading zeroes). By default, all ports on

the switch are members of VLAN 1. However, the management station can be attached to a port belonging to any

VLAN, as long as that VLAN has been assigned an IP address.
