The command automatically places all ports that are
not used for directly connected MAPs into the default
VLAN (VLAN 1).
CAUTION: The quickstart command is for configu-
ration of a new WX switch only. After prompting you
for verification, the command erases the switch's con-
figuration before continuing. If you run this command
on a switch that already has a configuration, the con-
figuration will be erased. In addition, error messages
such as "Critical AP Notice" for directly connected
MAPs can appear.
(The quickstart command does not configure Mobil-
ity Domain parameters, which are required for users
to roam across devices in the network. See "Config-
uring a Mobility Domain for Roaming" on page 8.)
Preparing the Network for Distributed MAPs
A MAP that is not directly connected to a WX switch
is considered a Distributed MAP. There can be inter-
mediate Layer 2 switches or Layer 3 IP routers
between the WX and MAP. The WX can communicate
with the Distributed MAP through any network port.
(A network port is any port connecting the switch to
other networking devices, such as switches and rout-
ers, and it can also be configured for 802.1Q VLAN

tagging.) The WX contains a configuration for a Dis-
tributed MAP based on the MAP's serial number. Sim-
ilar to ports configured for directly connected MAPs,
Distributed MAP configurations are numbered and
can reference a particular MAP. These numbered con-
figurations do not, however, reference any physical
port.
In addition to the WX switch configuration shown in
this document, Distributed MAPs require the follow-
ing support:
Power — PoE must be provided on one of the
Ethernet connections to the MAP. Be sure to use a
PoE injection device that has been tested by 3Com.
(Contact 3Com for information.)
DHCP — A Distributed MAP uses IP for communi-
cation, and relies on DHCP to obtain IP parame-
ters. Therefore, DHCP services must be available on
the subnet that the MAP is connected to. DHCP
must provide the following parameters to the
MAP:
IP address
Domain name
DNS server address
Gateway address
DNS — If the intermediate network between the
WX switch and Distributed MAP includes one or
more IP routers, create a 3COMWX.mynet-
work.com entry on the DNS server. The DNS entry
allows the MAP to communicate with a WX. If the
MAP is unable to locate a WX on the subnet it is
connected to, it performs a DNS query for
