History new draft

History: new draft

  • July 2006: discussion at IETF66 meeting

    • start the work on ANCP MIB for access nodes

    • call for contributors

      • Stefaan De Cnodder / Moti Morgenstern

  • October 2006: first draft submitteddraft-decnodder-ancp-mib-an-00.txt

    • ANCP MIB for the Access Node

    • MIB for NAS is not part of this document


Overview mib

Overview MIB

  • The MIB manages Access Node Control Sessions

    • 2 tables are defined

      • ancpAnSessionConfigTable

      • ancpAnCurrentSessionTable

    • 2 notifications to indicate ANCP session state changes

    • 3 groups are defined

    • 2 textual conventions

      • GsmpSubVersion

      • AnSessionCapabilities

      • other textual conventions taken from other MIBs (e.g., GSMP-MIB)


Ancpansessionconfigtable

ancpAnSessionConfigTable

  • to configure ANCP sessions to a particular NAS

  • Attributes:

    • attributes to identify the NAS: IP address and type

    • attributes to configure properties of the ANCP session

      • example: capabilities, version, retry timers for transport protocol, ...

  • Index of the table

    • is unsigned32 (sessionId)

    • stand-alone attribute (ancpAnNextSessionId) to get an unused sessionid


Ancpancurrentsessiontable

ancpAnCurrentSessionTable

  • to show the operational data of each ANCP session

    • example: negotiated capabilities, version, ...

  • each row created/deleted in ancpAnSessionConfigTable results in a row being created/deleted in this table

  • Index is taken from ancpAnSessionConfigTable


Notifications

Notifications

  • Notifications are generated when the state of an ANCP session changes:

    • ancpSessionDown: from UP to DOWN

      • session goes operational down

      • session is deleted from ancpAnSessionConfigTable

    • ancpSessionUp: from DOWN to UP


Next steps

Next Steps

  • Make in line with latest framework and requirements draft, in particular new section on “management related requirements”

    • partitions

  • What about NAS MIB?

    • framework/req stable enough to start MIB?

    • new MIB or one MIB for AN and NAS?

  • Comments!
