Establishing Connectivity on the Network

MAP Overview 189

Boot Process for When a distributed MAP boots on the network, it uses the process Distributed MAPs described in this section. Note that this process applies only to distributed

MAPs; it does not apply to a directly connected MAP. The boot process for a directly connected MAP occurs strictly between the MAP and WX switch and makes no use of the network’s DHCP or DNS services.

The boot process for a distributed MAP consists of the following steps:

1Establishing connectivity on the network

2Contacting a WX switch

3Loading and activating an operational image

4Obtaining configuration information from the WX switch

These steps are described in more detail in the following sections.

When a MAP is first powered on, its bootloader obtains an IP address for the MAP. The IP address is either obtained through DHCP (the default) or can be statically configured on the MAP.

How a Distributed MAP Obtains an IP Address through DHCP

By default, a distributed MAP obtains its IP address through DHCP. The MAP brings up the link on the MAP’s port 1 and attempts the boot process outlined below.

1The MAP sends a DHCP Discover message from the MAP’s port 1 to the broadcast address.

2If a DHCP server is present on the subnet or through a router configured to relay DHCP, the server replies with a unicast DHCP Offer message. The Offer message must contain the following parameters:

IP address for the MAP

Domain name of the network

IP address of the network’s DNS server

IP address of the subnet’s default gateway router (gateway)

Optionally, the DHCP Offer message can also contain a list of WX IP addresses or fully qualified hostnames, in the Option 43 field.

3The MAP broadcasts a DHCP Request to the DHCP servers, and receives an Ack from a DHCP server. The MAP then configures its network connection with the information contained in the Ack message from that server.
