Configuring IP Addressing
IP Configuration
use the menu interface or the CLI to manually configure the initial IP values.
After you have network access to a device, you can use the web browser
interface to modify the initial IP configuration if needed.
For information on how IP addressing affects switch operation, refer to “How
IP Addressing Affects Switch Operation” on page 8-11.
Multinetting: Assigning Multiple IP Addresses to a VLAN. For a given
VLAN you can assign up to 8 IP addresses. This allows you to combine two or
more subnets on the same VLAN, which enables devices in the combined
subnets to communicate normally through the network without needing to
reconfigure the IP addressing in any of the combined subnets.
Default Gateway Operation. The default gateway is required when a
router is needed for tasks such as reaching off-subnet destinations or forward-
ing traffic across multiple VLANs. The gateway value is the IP address of the
next-hop gateway node for the switch, which is used if the requested destina-
tion address is not on a local subnet/VLAN. If the switch does not have a
manually-configured default gateway and DHCP/Bootp is configured on the
primary VLAN, then the default gateway value provided by the DHCP or Bootp
server will be used. If the switch has a manually configured default gateway,
then the switch uses his gateway, even if a different gateway is received via
DHCP or Bootp on the primary VLAN. This is also true for manually configured
TimeP, SNTP, and Time-To-Live(TTL). (In the default configuration, VLAN 1
is the Primary VLAN.) Refer to the information on Primary VLANs in the
Advanced Traffic Management Guide for your switch.
Packet Time-To-Live (TTL) . This parameter specifies the maximum num-
ber of routers (hops) through which a packet can pass before being discarded.
Each router decreases a packet’s TTL by 1 before forwarding the packet. If
decreasing the TTL causes the TTL to be 0, the router drops the packet instead
of forwarding it. In most cases, the default setting (64) is adequate.
Just Want a Quick Start with IP Addressing?
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, ProCurve 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.
ProCurve# setup
■ Select 8. Run Setup in the Main Menu of the menu interface.
