Setup dialog box.
Switch Network Settings
Setting 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…001.
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 to 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.
