Get Connected Fields

Field

Description

Network Details

Protocol Type

Select the type of network connection:



Static—Select this option to enable the IP address, subnet mask, and gateway fields for

data entry.



DHCP—Select this option to enable the switch to obtain IP information from a DHCP

server on the network. If the DHCP server responds, then the assigned IP address is

used. If DHCP is enabled but the DHCP server does not respond, the default static IP

address 192.168.1.1 is used. DHCP operation is enabled by default.

When a DHCP server assigns an IP address to the switch, it specifies the time for which the

assignment is valid. After the time expires, the server may reclaim the address for assignment

to another device. When DHCP is enabled, you can click to send a request to the DHCP

server to renew the lease.
Only a user-configured static IP address is saved to flash.

CAUTION:

Changing the protocol type or IP address discontinues the current connection;

you can log on again using the new IP information.

IP Address

The IPv4 address for the switch.
If the Protocol Type is set to DHCP, this field displays the IP address assigned by the DHCP

server. If the Protocol Type is set to Static, the IP address can be manually configured in this

field. The default IP address is 192.168.1.1.

Note

: A broadcast, multicast, or network IP address should not be entered in this field.

Subnet Mask

The IPv4 subnet address to be used. The default IP subnet address is 255.255.255.0.

Gateway Address

The IPv4 gateway address to be used. When in doubt, set this to be the same as the default

gateway address used by your PC.

MAC Address

The hardware MAC address of this switch.

Web Parameters

Session Timeout

Specify the amount of time in minutes that a connection to the web interface remains active,

assuming no user activity. The range is 1 to 60 and the default is 5 minutes. To keep the

connection active regardless of user activity, set this value to 0.

CAUTION:

When a session window is closed without logging out, the server connection

remains open until the session times out. When the session timeout is set to 0, closing a

session window without logging out keeps the session open at the server indefinitely. In such

cases, you may fail to connect after the maximum sessions are left open indefinitely.

Management Access

Management VLAN ID

Access to the management software is controlled by the assignment of a management VLAN

ID. Only ports that are members of the management VLAN allow access to the management

software.
By default, the management VLAN ID is 1. The management VLAN can be any value

between 1 and 4093. All ports are members of VLAN 1 by default; the administrator may want

to create a different VLAN to assign as the management VLAN and associate it with a

management port (see the next field).
A VLAN that does not have any member ports (either tagged or untagged) cannot be

configured as the management VLAN.
When the network protocol is configured to be DHCP, any change in the configured

management VLAN ID may cause disruption in connectivity because the switch acquires a

new IP address when the management subnet is changed. To reconnect to the switch, the

user must determine the new IP address by viewing the log on the DHCP server.
