Advanced Services

This section describes the contents, parameters, and default settings for all Advanced Services components in
Dell PowerConnect W Configuration. Dell PowerConnect W Configuration in AirWave supports advanced
services such as IP Mobility and VPN services. F

Overview of IP Mobility Domains

Dell PowerConnect W's layer-3 mobility solution is based on the Mobile IP protocol standard, as described in
RFC 3344, "IP Mobility Support for IPv4". This standard addresses users who need both network connectivity
and mobility within the work environment.
Unlike other layer-3 mobility solutions, the Dell PowerConnect W mobility solution does not require that you
install mobility software or perform additional configuration on wireless clients. The Dell PowerConnect W-
Series controllers perform all functions that enable clients to roam within the mobility domain.
In a mobility domain, a mobile client is a wireless client that can change its point of attachment from one
network to another within the domain. A mobile client receives an IP address (a home address) on a home
network. A mobile client can detach at any time from its home network and reconnect to a foreign network (any
network other than the mobile client's home network) within the mobility domain. When a mobile client is
connected to a foreign network, it is bound to a care-of address that reflects its current point of attachment. A
care-of address is the IP address of the Dell PowerConnect W-Series controller in the foreign network with which
the mobile client is associated.
The home agent for the client is the controller where the client appears for the first time when it joins the mobility
domain. The home agent is the single point of contact for the client when the client roams. The foreign agent for
the client is the controller which handles all Mobile IP communication with the home agent on behalf of the
client. Traffic sent to a client's home address is intercepted by the home agent and tunneled for delivery to the

Description
A string representing the name of the user.
An indication of whether messages sent on behalf of this user can be authenticated, and
if so, the type of authentication protocol used. This can take one of the two values:


If messages sent on behalf of this user can be authenticated, the (private) authentication
key for use with the authentication protocol. This is a string password for MD5 or SHA
depending on the choice above.
An indication of whether messages sent on behalf of this user can be protected from
disclosure, and if so, the type of privacy protocol which is used. This takes the value DES
(CBC-DES Symmetric Encryption Protocol).
If messages sent on behalf of this user can be encrypted/decrypted with DES, the
(private) privacy key for use with the privacy protocol.
MD5: HMAC-MD5-96 Digest Authentication Protocol
SHA: HMAC-SHA-96 Digest Authentication Protocol
