name of the VCS and the means by which it is accessed by
administrators.

About the system name
The system name is used to identify the VCS. It appears in
various places in the web interface, and in the display on the
front panel of the unit (so that you can identify it when it is in a
rack with other systems). The system name is also used by Cisco
TMS.

We recommend that you give the VCS a name that allows
you to easily and uniquely identify it.

About administration access settings
While it is possible to administer the VCS by using a PC
connected directly to the unit via a serial cable, you may want to
access the system remotely over IP.
You can do this using either or both:

By default, access via HTTPS and SSH is enabled; access via
Telnet is disabled.
You can also enable access via HTTP. However, this mode works
by redirecting HTTP calls to the HTTPS port, so HTTPS must also
be enabled for access via HTTP to function.
The Session time out setting controls whether the system
automatically logs out the current user after a configurable period
of inactivity.

is connected.

About Ethernet speed
The Ethernet speed setting determines the speed of the
connection between the VCS and the Ethernet switch. It must be
set to the same value on both systems.
If you have the Dual Network Interfaces option key installed, you
will be able to configure the speed for both the LAN 1 and LAN 2
ports separately.
The default is Auto, which means that the two systems will auto-
negotiate the appropriate speed.

You should only change the default value from Auto if
the switch to which you are connecting is unable to
auto-negotiate. A mismatch in Ethernet speed settings
