1 The MAP sends a DHCP Discover message from the MAP port 1.
2 DHCP server receives the Discover message (through a relay agent) and
replies with a DHCP Offer message containing IP address for the MAP,
the router IP address for the MAP IP subnet, the DNS server address, and
the domain name. MAP then sends a DHCP Request message to the
server and receives an Ack from the server.
3 MAP sends a broadcast Find WX message to IP subnet broadcast address.
4 WX1 and WX3 have high priority for the MAP and reply immediately.
5 The MAP contacts WX1 and determines whether it should use a locally
stored operational image or download it from the WX switch.
WX1 is contacted because it has fewer active MAP connections than
WX3. Once the operational image is loaded, the MAP requests
configuration information from WX1.
