Network Settings Description
Management Interface (VLAN ID) The name and ID of the management VLAN through which the switch will be managed.
Select an existing VLAN to be the management VLAN.
The default ID is 1. The default name for the management VLAN is default. The number
can be from 1…1001.
Make sure that the switch and your network management station are in the same VLAN.
Otherwise, you lose management connectivity to the switch.
The management VLAN is the broadcast domain through which management traffic is
sent between specific users or devices. It provides broadcast control and security for
management traffic that should be limited to a specific group of users (such as the
administrators of your network). It also ensures secure administrative access to all
devices in the network at all times.
Refer to VLANs on page 31
for more information about management VLANs and about
VLANs in general.
IP Assignment Mode The IP Assignment mode determines if the switch IP information is manually assigned
(Static) or is automatically assigned by a Dynamic Host Configuration Protocol (DHCP)
server. The default is Static.
We recommend that you select Static and manually assign the IP address for the switch.
You can then use the same IP address whenever you want to access the Device Manager
Web interface.
If you select DHCP, the DHCP server automatically assigns an IP address, subnet mask,
and default gateway to the switch. As long as the switch is not restarted, the switch
continues to use the assigned IP information, and you are able to use the same IP
address to access the Device Manager Web interface.
If you manually assign the switch IP address and your network uses a DHCP server, make
sure that the IP address that you give to the switch is not within the range of addresses
that the DHCP server will automatically assign to other devices. This prevents IP-address
conflicts between the switch and another device.
IP Address The IP address is a unique identifier for the switch in a network. The format is a 32-bit
numeric address written as four numbers separated by periods. Each number can be
from 0…255.
This field is enabled only if the IP Assignment mode is Static.
Make sure that the IP address that you assign to the switch is not being used by another
device in your network. The IP address and the default gateway cannot be the same. You
cannot assign the switch with an IP address in the 10.0.0.0 network.
Subnet Mask List The subnet mask is the network address that identifies the subnetwork (subnet) to which
the switch belongs. Subnets are used to segment the devices in a network into smaller
groups. The default is 255.255.255.0.
This field is enabled only if the IP Assignment mode is Static.
