Configuring the IP Management Interface

These instructions include information on defining an
out-of-band IP management interface through which
you can manage your system.

In-band or Out-of-band Management?

If you manage your system and its attached LANs over
the same network that carries your regular data
traffic, then you are managing your system in-band.
This kind of management is often the most
convenient and inexpensive way to access your
system. The disadvantage is that, if your data network
is faulty, you may not be able to diagnose the
problem because the management requests are sent
over the same troubled network.
If you are managing your system using a dedicated
network for management data, then you are
managing your network out-of-band.

In-band Management

To manage your network in-band, you need to set up
an IP routing interface. You can then choose to
manage in-band through a VLAN, or using a port. See
the Command Reference Guide for information on
how to set up an IP routing interface.
