    Description by circitor

    This MIB is intended to be implemented on IEEE
    802.11 Wireless LAN management devices for Access
    Points and Wireless Bridges participating in the
    context management process and making use of
    the services provided by entities offering WDS
    and WNS. This MIB allows NMS to access individual
    configuration of wireless stations through the
    SNMP agent at the management device, i.e. WSA.

    The term '802.11 station' or 'wireless station'
    refers to one of the Access Point or Wireless
    Bridge throughout the MIB unless stated otherwise.

    The hierarchy of the devices offering the wireless
    domain and network services looks like the following.

    The diagram above depicts the overall campus network
    hierarchy and the services being offered at various
    levels in the hierarchy. Here, authentication
    services for infrastructure nodes are offered by the
    root node, the node providing WNS at the topmost
    (Campus) level. This node spans an enterprise campus
    that resides in a geographic location. In this case,
    an 802.11 station performs initial authentication
    with the topmost WNS entity. It also gets the keys
    needed for secure context transfer by communication
    with that entity.

    WNS are offered at various levels as shown in the
    hierarchy to achieve scalability. WNS at the
    subsequent levels other than the root level include
    authentication services for MNs and are typically
    confined to a single building.

    At the broadcast domain level, the WDS includes
    authentication and registration services for the APs.
    An AP provides proxy authentication and registration
    services for the MNs. The APs that connect to parent
    APs through the wireless interface ( as shown by the
    dotted lines ) are Repeater-APs. The WGBs are managed
    in the same manner as the MNs. However, the Ethernet
    Nodes ( EN ) that are connected to the WGB won't be
    served as part of the WDS.

    GLOSSARY

    Access Point ( AP )

    Any entity that contains an 802.11 medium access
    control ( MAC ) and physical layer ( PHY ) interface
    and provides access to the distribution services via
    the wireless medium for associated clients.

    Wireless Bridge

    An 802.11 entity that provides wireless connectivity
    between two wired LAN segments and is used in point-
    to-point or point-to-multipoint configurations.

    Mobile Node ( MN )

    A roaming 802.11 wireless device in a wireless
    network associated with an access point.


    WorkGroup Bridge ( WGB )

    A work-group bridge is a non-STP AP with an 802.11
    primary port and a secondary Ethernet port that
    provides access to a non-STP secondary Ethernet LAN
    segment. STP refers to the IEEE 802.1D Spanning Tree
    Protocol. An 'STP AP' executes the 802.1D STP and
    the 802.1D STP is operated on an 'STP link'. A
    'non-STP AP' does not execute the 802.1D STP.

    Repeater-AP

    A repeater is a 'wireless AP' that is attached to a
    parent AP on an 802.11 primary port. The Ethernet
    port is disabled in a Repeater-AP.

    Infrastructure Node ( IN )

    This term refers to Access Points, Wireless Bridges
    and those devices that implement and offer WNS and
    WDS as shown in the network hierarchy.

    Ethernet Node ( EN )

    The node that gets the uplink to the Wireless AP
    via the WGB. This node connects to the WGB through
    its primary Ethernet port.

    Context

    The mobility context for an MN includes its current
    mobility bindings with the APs, IP/802 address
    bindings, cached configuration parameters, QoS state,
    IP group membership, authentication state, accounting
    statistics, and other dynamically derived protocol
    state information.

    Wireless Domain Services

    The set of services being offered at a particular
    broadcast domain that may be an IP subnet or a
    particular VLAN. The services include the following.

    1. MN security credential caching to provide seamless,
    secure intra-subnet roaming.

    2. Authenticated context transfer for roaming client
    within the subnet.

    Since, by definition, the WDS are bound to one subnet
    ( broadcast domain ), if implemented in a device
    spanning multiple subnets, the implementation should
    take care to provide separate set of services for
    each of the subnets.


    Wireless Network Services

    The set of services that can be visualized as being
    offered at various levels other than the lowest
    (subnet) level of a hierarchical campus network.

    At the topmost level, infrastructure authentication
    services for all the devices in the network that
    provide WNS and WDS are offered. In case if WNS are
    not distributed at several levels as shown in the
    hierarchy above and is confined to be offered only at
    a single topmost level, the services offered also
    include authentication services for the MNs.

    WNS Entity

    The logical entity that resides in an infrastructure
    node and offers WNS to the descendants of that
    infrastructure node in the wireless services
    hierarchy.

    WDS Entity

    The logical entity that resides in an infrastructure
    node and offers WDS to the descendants of that
    infrastructure node in the wireless services
    hierarchy.

    WS Entity

    Refers to one of WNS / WDS Entities.

    Parent Node

    The entity that immediately precedes an infrastructure
    node in the hierarchy. For mobile nodes, the parent
    APs provide proxy wireless services by talking to their
    immediate parent entities providing WDS.

    Root Node

    The entity that is at the highest level in the network
    hierarchy. The root node acts as the IN Authenticator
    for the infrastructure nodes. In case if WNS are not
    distributed, the root node also acts as the Mobile Node
    Authenticator ( See description below ).

    Descendant

    A node that is in the sub-tree of the campus hierarchy
    tree rooted at the node providing WNS at the campus
    level.

    Infrastructure Node ( IN ) Authenticator

    The logical entity that communicates with the AAA
    server and provides authentication services for the
    infrastructure nodes. Details of the IN Authenticator
    has to be configured in the device providing WDS
    manually. The AP learns about the IN Authenticator
    automatically upon registering with its immediate
    parent. The WDS also includes MN authentication
    services if the entity providing WDS is at the
    topmost level in the hierarchy.

    Mobile Node ( MN ) Authenticator

    The logical entity that communicates with the AAA
    server and provides authentication services for mobile
    nodes. An infrastructure node learns the whereabouts
    of the MN Authenticator from the root node.

    Wireless Network Manager ( WNM )

    The network management system that manages the
    entire hierarchy of devices providing WNS and WDS.

    Advertisement

    The process by which the Access Points identify their
    parent entities providing WDS. APs listen to the
    advertisements of the WDS entities and gets registered
    with one of those entities to facilitate secured
    context transfer.

    WLCCP

    Wireless LAN Context Control Protocol. Used to
    establish and manage the network topology and
    securely manage the 'operational context' for mobile
    stations in a campus network.

    WSA

    Wireless Switch Architecture. A layer II switch
    which is capable of manage directly and indirectly
    attached 802.11 stations within a subnet.

    AAA

    Authentication, Authorization, Accounting

    The method by which users are authenticated,
    authorized and tracked to gain access and move about
    inside a network. A node will request network access
    through an appropriate protocol to an authentication
    server that provides protocols and services for
    providing authentication, authorization and session
    accounting.

    Service Set Identifier ( SSID )

    802.11 Service Set Identifier. An SSID identifies a
    set of mobile nodes grouped into a logical 'service
    set' and the APs that provide access for the service
    set.

    being offered in a network rooted at the device
    implementing WDS. In such a network, the WDS entity
    provides authentication services to both the
    infrastructure and mobile nodes.

    An 802.11 station in this hierarchy mentioned above
    performs the following.

    1) Provides proxy authentication and registration
    services to the MNs, WGBs and repeater-APs. The
    station forwards all the authentication and
    registration requests of its clients to its parent
    node offering WDS and acting as the IN Authenticator
    to enable the authentication and registration of its
    clients.

    2) Participates in the election process to elect
    the node that will provide WDS for a particular
    broadcast domain.

    The diagram above depicts the overall campus network
    hierarchy and the services being offered at various
    levels in the hierarchy. Here, authentication
    services for infrastructure nodes are offered by the
    root node, the node providing WNS at the topmost
    (Campus) level. This node spans an enterprise campus
    that resides in a geographic location. In this case,
    an 802.11 station performs initial authentication
    with the topmost WNS entity. It also gets the keys
    needed for secure context transfer by communication
    with that entity.

    WNS are offered at various levels as shown in the
    hierarchy to achieve scalability. WNS at the
    subsequent levels other than the root level include
    authentication services for MNs and are typically
    confined to a single building.

    At the broadcast domain level, the WDS includes
    authentication and registration services for the APs.
    An AP provides proxy authentication and registration
    services for the MNs. The APs that connect to parent
    APs through the wireless interface ( as shown by the
    dotted lines ) are Repeater-APs. The WGBs are managed
    in the same manner as the MNs. However, the Ethernet
    Nodes ( EN ) that are connected to the WGB won't be
    served as part of the WDS.

    GLOSSARY

    Access Point ( AP )

    Any entity that contains an 802.11 medium access
    control ( MAC ) and physical layer ( PHY ) interface
    and provides access to the distribution services via
    the wireless medium for associated clients.

    Wireless Bridge

    An 802.11 entity that provides wireless connectivity
    between two wired LAN segments and is used in point-
    to-point or point-to-multipoint configurations.

    Mobile Node ( MN )

    A roaming 802.11 wireless device in a wireless
    network associated with an access point.


    WorkGroup Bridge ( WGB )

    A work-group bridge is a non-STP AP with an 802.11
    primary port and a secondary Ethernet port that
    provides access to a non-STP secondary Ethernet LAN
    segment. STP refers to the IEEE 802.1D Spanning Tree
    Protocol. An 'STP AP' executes the 802.1D STP and
    the 802.1D STP is operated on an 'STP link'. A
    'non-STP AP' does not execute the 802.1D STP.

    Repeater-AP

    A repeater is a 'wireless AP' that is attached to a
    parent AP on an 802.11 primary port. The Ethernet
    port is disabled in a Repeater-AP.

    Infrastructure Node ( IN )

    This term refers to Access Points, Wireless Bridges
    and those devices that implement and offer WNS and
    WDS as shown in the network hierarchy.

    Ethernet Node ( EN )

    The node that gets the uplink to the Wireless AP
    via the WGB. This node connects to the WGB through
    its primary Ethernet port.

    Context

    The mobility context for an MN includes its current
    mobility bindings with the APs, IP/802 address
    bindings, cached configuration parameters, QoS state,
    IP group membership, authentication state, accounting
    statistics, and other dynamically derived protocol
    state information.

    Wireless Domain Services

    The set of services being offered at a particular
    broadcast domain that may be an IP subnet or a
    particular VLAN. The services include the following.

    1. MN security credential caching to provide seamless,
    secure intra-subnet roaming.

    2. Authenticated context transfer for roaming client
    within the subnet.

    Since, by definition, the WDS are bound to one subnet
    ( broadcast domain ), if implemented in a device
    spanning multiple subnets, the implementation should
    take care to provide separate set of services for
    each of the subnets.


    Wireless Network Services

    The set of services that can be visualized as being
    offered at various levels other than the lowest
    (subnet) level of a hierarchical campus network.

    At the topmost level, infrastructure authentication
    services for all the devices in the network that
    provide WNS and WDS are offered. In case if WNS are
    not distributed at several levels as shown in the
    hierarchy above and is confined to be offered only at
    a single topmost level, the services offered also
    include authentication services for the MNs.

    WNS Entity

    The logical entity that resides in an infrastructure
    node and offers WNS to the descendants of that
    infrastructure node in the wireless services
    hierarchy.

    WDS Entity

    The logical entity that resides in an infrastructure
    node and offers WDS to the descendants of that
    infrastructure node in the wireless services
    hierarchy.

    WS Entity

    Refers to one of WNS / WDS Entities.

    Parent Node

    The entity that immediately precedes an infrastructure
    node in the hierarchy. For mobile nodes, the parent
    APs provide proxy wireless services by talking to their
    immediate parent entities providing WDS.

    Root Node

    The entity that is at the highest level in the network
    hierarchy. The root node acts as the IN Authenticator
    for the infrastructure nodes. In case if WNS are not
    distributed, the root node also acts as the Mobile Node
    Authenticator ( See description below ).

    Descendant

    A node that is in the sub-tree of the campus hierarchy
    tree rooted at the node providing WNS at the campus
    level.

    Infrastructure Node ( IN ) Authenticator

    The logical entity that communicates with the AAA
    server and provides authentication services for the
    infrastructure nodes. Details of the IN Authenticator
    has to be configured in the device providing WDS
    manually. The AP learns about the IN Authenticator
    automatically upon registering with its immediate
    parent. The WDS also includes MN authentication
    services if the entity providing WDS is at the
    topmost level in the hierarchy.

    Mobile Node ( MN ) Authenticator

    The logical entity that communicates with the AAA
    server and provides authentication services for mobile
    nodes. An infrastructure node learns the whereabouts
    of the MN Authenticator from the root node.

    Wireless Network Manager ( WNM )

    The network management system that manages the
    entire hierarchy of devices providing WNS and WDS.

    Advertisement

    The process by which the Access Points identify their
    parent entities providing WDS. APs listen to the
    advertisements of the WDS entities and gets registered
    with one of those entities to facilitate secured
    context transfer.

    WLCCP

    Wireless LAN Context Control Protocol. Used to
    establish and manage the network topology and
    securely manage the 'operational context' for mobile
    stations in a campus network.

    WSA

    Wireless Switch Architecture. A layer II switch
    which is capable of manage directly and indirectly
    attached 802.11 stations within a subnet.

    AAA

    Authentication, Authorization, Accounting

    The method by which users are authenticated,
    authorized and tracked to gain access and move about
    inside a network. A node will request network access
    through an appropriate protocol to an authentication
    server that provides protocols and services for
    providing authentication, authorization and session
    accounting.

    Service Set Identifier ( SSID )

    802.11 Service Set Identifier. An SSID identifies a
    set of mobile nodes grouped into a logical 'service
    set' and the APs that provide access for the service
    set.

    The above diagram depicts how wireless services are
    being offered in a network rooted at the device
    implementing WDS. In such a network, the WDS entity
    provides authentication services to both the
    infrastructure and mobile nodes.

    An 802.11 station in this hierarchy mentioned above
    performs the following.

    1) Provides proxy authentication and registration
    services to the MNs, WGBs and repeater-APs. The
    station forwards all the authentication and
    registration requests of its clients to its parent
    node offering WDS and acting as the IN Authenticator
    to enable the authentication and registration of its
    clients.

    2) Participates in the election process to elect
    the node that will provide WDS for a particular
    broadcast domain.

This MIB allows NMS to access individual configuration of wireless stations through the SNMP agent at the management device, i.e. WSA. The term '802.11 station' or 'wireless station' refers to one of the Access Point or Wireless Bridge throughout the MIB unless stated otherwise. The hierarchy of the devices offering the wireless domain and network services looks like the following. += = = = + | | | WNS | (Campus level) | | += = = = + / \ / \ / \ / \ \/ \/ += = =+ += = =+ | | | | | WNS | | WNS | | | | | += = =+ += = =+ / \ \ / \ \ / \ \ / \ \ \/ \/ \/ +=====+ +=====+ + | | | | | | | | | WDS | | WDS | | WSA | | WDS | ( Subnet | | | | | | | | level- +=====+ +=====+ + / \ \ :: :: \ broadcast / \ \ :: :: \ domain ) / \ \ :: :: \ / \ \ :: :: \ / \ \ :: :: \ \/ \/ \/ :: :: \/ +~-~-~+ +~-~-~+ +~-~-~+ +~-~-~+ + + + + + + + + + AP + + AP + + AP + + AP + + + + + + + + + +~-~-~+ +~-~-~+ +~-~-~+ +~-~-~+ .. . . . . . . . . . . . . . . . . . . . . . . . \/ \/ \/ \/ \/ +.....+ +.....+ +-.-.-.+ +~-~-~+ +......+ + + + + + + + + + + + MN + + MN + + WGB + + AP + + MN + + + + + + + + + + + +.....+ +.....+ +-.-.-.+ +~-~-~+ +......+ . . . . . . . . . . . . \/ \/ \/ ++++++++ +......+ +......+ + + + + + + + EN + + MN + + MN + + + + + + + ++++++++ +......+ +......+ The diagram above depicts the overall campus network hierarchy and the services being offered at various levels in the hierarchy. Here, authentication services for infrastructure nodes are offered by the root node, the node providing WNS at the topmost (Campus) level. This node spans an enterprise campus that resides in a geographic location. In this case, an 802.11 station performs initial authentication with the topmost WNS entity. It also gets the keys needed for secure context transfer by communication with that entity. WNS are offered at various levels as shown in the hierarchy to achieve scalability. WNS at the subsequent levels other than the root level include authentication services for MNs and are typically confined to a single building. At the broadcast domain level, the WDS includes authentication and registration services for the APs. An AP provides proxy authentication and registration services for the MNs. The APs that connect to parent APs through the wireless interface ( as shown by the dotted lines ) are Repeater-APs. The WGBs are managed in the same manner as the MNs. However, the Ethernet Nodes ( EN ) that are connected to the WGB won't be served as part of the WDS. GLOSSARY Access Point ( AP ) Any entity that contains an 802.11 medium access control ( MAC ) and physical layer ( PHY ) interface and provides access to the distribution services via the wireless medium for associated clients. Wireless Bridge An 802.11 entity that provides wireless connectivity between two wired LAN segments and is used in point- to-point or point-to-multipoint configurations. Mobile Node ( MN ) A roaming 802.11 wireless device in a wireless network associated with an access point. WorkGroup Bridge ( WGB ) A work-group bridge is a non-STP AP with an 802.11 primary port and a secondary Ethernet port that provides access to a non-STP secondary Ethernet LAN segment. STP refers to the IEEE 802.1D Spanning Tree Protocol. An 'STP AP' executes the 802.1D STP and the 802.1D STP is operated on an 'STP link'. A 'non-STP AP' does not execute the 802.1D STP. Repeater-AP A repeater is a 'wireless AP' that is attached to a parent AP on an 802.11 primary port. The Ethernet port is disabled in a Repeater-AP. Infrastructure Node ( IN ) This term refers to Access Points, Wireless Bridges and those devices that implement and offer WNS and WDS as shown in the network hierarchy. Ethernet Node ( EN ) The node that gets the uplink to the Wireless AP via the WGB. This node connects to the WGB through its primary Ethernet port. Context The mobility context for an MN includes its current mobility bindings with the APs, IP/802 address bindings, cached configuration parameters, QoS state, IP group membership, authentication state, accounting statistics, and other dynamically derived protocol state information. Wireless Domain Services The set of services being offered at a particular broadcast domain that may be an IP subnet or a particular VLAN. The services include the following. 1. MN security credential caching to provide seamless, secure intra-subnet roaming. 2. Authenticated context transfer for roaming client within the subnet. Since, by definition, the WDS are bound to one subnet ( broadcast domain ), if implemented in a device spanning multiple subnets, the implementation should take care to provide separate set of services for each of the subnets. Wireless Network Services The set of services that can be visualized as being offered at various levels other than the lowest (subnet) level of a hierarchical campus network. At the topmost level, infrastructure authentication services for all the devices in the network that provide WNS and WDS are offered. In case if WNS are not distributed at several levels as shown in the hierarchy above and is confined to be offered only at a single topmost level, the services offered also include authentication services for the MNs. WNS Entity The logical entity that resides in an infrastructure node and offers WNS to the descendants of that infrastructure node in the wireless services hierarchy. WDS Entity The logical entity that resides in an infrastructure node and offers WDS to the descendants of that infrastructure node in the wireless services hierarchy. WS Entity Refers to one of WNS / WDS Entities. Parent Node The entity that immediately precedes an infrastructure node in the hierarchy. For mobile nodes, the parent APs provide proxy wireless services by talking to their immediate parent entities providing WDS. Root Node The entity that is at the highest level in the network hierarchy. The root node acts as the IN Authenticator for the infrastructure nodes. In case if WNS are not distributed, the root node also acts as the Mobile Node Authenticator ( See description below ). Descendant A node that is in the sub-tree of the campus hierarchy tree rooted at the node providing WNS at the campus level. Infrastructure Node ( IN ) Authenticator The logical entity that communicates with the AAA server and provides authentication services for the infrastructure nodes. Details of the IN Authenticator has to be configured in the device providing WDS manually. The AP learns about the IN Authenticator automatically upon registering with its immediate parent. The WDS also includes MN authentication services if the entity providing WDS is at the topmost level in the hierarchy. Mobile Node ( MN ) Authenticator The logical entity that communicates with the AAA server and provides authentication services for mobile nodes. An infrastructure node learns the whereabouts of the MN Authenticator from the root node. Wireless Network Manager ( WNM ) The network management system that manages the entire hierarchy of devices providing WNS and WDS. Advertisement The process by which the Access Points identify their parent entities providing WDS. APs listen to the advertisements of the WDS entities and gets registered with one of those entities to facilitate secured context transfer. WLCCP Wireless LAN Context Control Protocol. Used to establish and manage the network topology and securely manage the 'operational context' for mobile stations in a campus network. WSA Wireless Switch Architecture. A layer II switch which is capable of manage directly and indirectly attached 802.11 stations within a subnet. AAA Authentication, Authorization, Accounting The method by which users are authenticated, authorized and tracked to gain access and move about inside a network. A node will request network access through an appropriate protocol to an authentication server that provides protocols and services for providing authentication, authorization and session accounting. Service Set Identifier ( SSID ) 802.11 Service Set Identifier. An SSID identifies a set of mobile nodes grouped into a logical 'service set' and the APs that provide access for the service set.
