Configuring IP Addressing
IP Configuration
How IP Addressing Affects Switch Operation
Without an IP address and subnet mask compatible with your network, the
switch can be managed only through a direct terminal device connection to
the Console RS-232 port. You can use direct-connect console access to take
advantage of features that do not depend on IP addressing. However, to realize
the full performance capabilities HP proactive networking offers through the
switch, configure the switch with an IP address and subnet mask compatible
with your network. The following table lists the general features available with
and without a network-compatible IP address configured.
