If the serial number does not match and the Auto-Config IP Subnet
Matching option is disabled, 3WXM cannot give the switch a
configuration. 3WXM generates a verification warning (on the
Network Verification tab). The warning lists the switch’s serial
number and IP address. The network administrator can upload the
switch into the network plan, configure switch parameters, and
deploy the configuration to the switch. (See “Uploading a Partially
Configured Switch and Completing its Configuration with 3WXM”
on page 343.)
Staged WX
1 The switch is shipped to a network administrator who configures IP
address and DNS information on the switch, and enables the auto-config
option, to configure the switch to contact 3WXM Services in the
corporate network.
The network administrator can configure the switch to use a DCHP client
to obtain IP information, or can statically configure the information. The
IP address and default gateway are required.
DNS information is optional, but is recommended if DNS is available. If
DNS is available, an entry must be added to the DNS server that maps the
IP address of the host where 3WXM Service are installed to the
well-known hostname wlan-config-srv. Otherwise, an IP alias can be
configured on the switch itself to map the address to the hostname.
2 The preconfigured switch is shipped to the remote office where it will be
deployed.
3 Someone at the remote office physically installs the switch and MAPs.
4 The person at the remote office powers the switch on. The switch boots
using the configuration created during staging.
5 The switch either uses its DHCP client to obtain an IP address from a local
DHCP server, or uses a statically configured address. This depends on the
switch’s preconfiguration.
6 If the auto-config option is enabled, the switch sends a DNS query for the
IP address of well-known hostname wlan-config-srv.
7 DNS replies with the IP address of the host where 3WXM Services are
installed. The switch sends a request to 3WXM Services in the corporate
network for a configuration. (If the auto-config option is not enabled, the
switch boots using its configuration file. You can use the CLI, 3WXM, or
Web Management to complete its configuration.)
