Wireless DHCP (WDHCP)
The Wireless Dynamic Host Configuration Protocol (WDHCP) provides the dynamic assignment
of IP addresses to the CSC. The IP addresses are assigned and maintained by the WAW
Network. WDHCP allows CSCs to associate with any MBS2-LP to gain access to the WAW
Network.
WDHCP relies on the Wireless Modem Discovery (WMD) protocol: a simple protocol used by
client CSCs to query for the availability of MBS2-LPs within their communication range. Once the
MBS2-LP is selected, the CSC registers with a WDHCP server in the NOSS, which processes the
request and assigns the IP address to the CSC
Internet Protocols Support
The MBS2-LP is capable of supporting the following IP-based protocols:
• DHCP client and server on all MBS2-LP IP-capable interfaces
• Standard IP routing between all MBS2-LP IP-capable interfaces
• PPP over the Serial Interface
• ICMP Ping from the MBS2-LP to the user-specified address
• Telnet and TFTP firmware downloads from all MBS2-LP IP-capable interfaces
