Just Want a Quick Start?
If you just want to give the switch an IP address so that it can communicate
on your network, or if you are not using VLANs, HP recommends that you use
the Switch Setup screen to quickly configure IP addressing. To do so, do one
of the following:
■ Enter setup at the CLI Manager level prompt.
HP4108# setup
■ Select 8. Run Setup in the Main Menu of the menu interface.
For more on using the Switch Setup screen, see the Installation and Getting
Started Guide
you received with the switch.
IP Addressing with Multiple VLANs
In the factory-default configuration, the switch has one, permanent default
VLAN (named DEFAULT_VLAN) that includes all ports on the switch. Thus,
when only the default VLAN exists in the switch, if you assign an IP address
and subnet mask to the switch, you are actually assigning the IP addressing
to the DEFAULT_VLAN.
N o t e s ■ If multiple VLANs are configured, then each VLAN can have its own IP
address. This is because each VLAN operates as a separate broadcast
domain and requires a unique IP address and subnet mask. A default
gateway (IP) address for the switch is optional, but recommended.
■ In the factory-default configuration, the default VLAN (named
DEFAULT_VLAN) is the switch’s primary VLAN. The switch uses the
primary VLAN for learning the default gateway address, (packet) Time-
To-Live (TTL), and Timep via DHCP or Bootp. (Other VLANs can also use
DHCP or BootP to acquire IP addressing. However, the switch’s gateway,
TTL, and TimeP values will be acquired through the primary VLAN only.)
For more on VLANs, refer to “Port-Based Virtual LANs (Static VLANs)”
on page 14-4.
■ The IP addressing used in the switch should be compatible with your
network. That is, the IP address must be unique and the subnet mask must
be appropriate for your IP network.
■ If you plan to connect to other networks that use globally administered
IP addresses, refer to “Globally Assigned IP Network Addresses” on page
7-14.
