Expires May 29, 2010 [Page 2] Internet-Draft ANCP NAS MIB November 2009 1. Introduction This memo defines a portion of the Management Information Base (MIB) for managing Network Access Servers (NAS) that are using Access Node Control Protocol defined in [ANCPPR] 2. Conventions The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. 3. Overview In [ANCPFW], the framework for the Access Node Control Protocol (ANCP) is described. It defines 2 network entities, the Access Node (AN) and the Network Access Server (NAS), between which ANCP sessions are established. The detailed protocol specification of ANCP is described in [ANCPPR]. This document specifies a MIB module for a Network Access Server that supports ANCP. Note: the current MIB definition is specific for [ANCPPR] If [ANCPPR] gets updated later, then the MIB definition in this document will also follow these changes. 4. Structure of the MIB Module 4.1. Textual Conventions The following new textual conventions are introduced: AncpSessionState, AncpSessionCapabilities, AncpDslLineState, and AncpDslLineType. 4.2. The ANCP NAS MIB Module Subtree This document defines mib modules ANCP-NAS-MIB under mib-2. 4.3. The Notifications Subtree Notifications are defined to inform the management station about state changes of ANCP sessions and ANCP ports. The notification ancpNasPortUp is to inform the management station when a ANCP Port-Up message is received, and ancpNasPortDown is to inform when a ANCP Port-Down message is received. The notification ancpNasSessionUp is to inform when a session comes up and ancpNasSessionDown to inform Rohit, et al. Expires May 29, 2010 [Page 3] Internet-Draft ANCP NAS MIB November 2009 session going down. To enable and disable the generation of these notifications, attributes ancpNasPortStatusNotifEnable and ancpNasSessionNotifEnable are defined. The attribute ancpNasPortStatusNotifEnable controls the generation of ancpNasPortUp and ancpNasPortDown, and ancpNasPortStatusNotifEnable controls the generation of ancpNasSessionUp and ancpNasSessionDown. 4.4. The Table Structures The ANCP MIB module for the NAS has the following tables: o ancpNasIfConfigTable This table is used to configure interface specific ANCP parameters including neighbors (i.e DSLAMs). A neighbor is identified with a name, ID and a client-ID. The name is generally the hostname of the neighbor, neighbor's IP or MAC can be used as the ID which is unique. The client-ID is the port's identity, or the Access-Loop- Circuit-ID which will take a well defined form based on the access technology used. In the case of ATM based local loop, the string will be of the form: Access-Node-Identifier atm slot/port:vpi.vci In case of Ethernet based (and tagged) local loop, the string will be of the form: Access-Node-Identifier eth slot/port[:vlan-id] o ancpNasSessionTable This table shows the operational state of ANCP sessions on the NAS. o ancpNasPortTable This table shows the ports known to the NAS and their state and DSL line parameters. The ports can be configured or learnt (via ANCP Event messages). Configured ports have a corresponding entry in the ancpNasIfConfigTable. Following groups are defined: o ancpNasSessionGroup This group contains all objects specific to ANCP session. Rohit, et al. Expires May 29, 2010 [Page 4] Internet-Draft ANCP NAS MIB November 2009 o ancpNasPortGroup This group contains all port specific objects for ANCP. o ancpNasConfigGroup This group contains all configurable objects for ANCP. o ancpNasNotifControlGroup This group contains the attributes which control the generation of ANCP session and port status notifications. o ancpNasNotificationGroup This group contains the notifications that indicate state changes of ANCP sessions and ports (ancpNasNotifications). 5. Relationship With Other MIB Modules ANCP NAS MIB module uses ifIndex (defined in ifTable of IF-MIB [RFC2863]) to index ancpNasIfConfigTable. 5.1. MIB modules required for IMPORTS The ANCP MIB module for Network Access Server requires following MIB modules for IMPORTS: o SNMPv2-SMI defined in [RFC2578] o RMON2-MIB defined in [RFC4502] o IF-MIB defined in [RFC2863] o INET-ADDRESS-MIB defined in [RFC4001] o SNMPv2-CONF defined in [RFC2580] o GSMP-MIB defined in [RFC3295] o SNMPv2-TC defined in [RFC2579] 6.

Security Considerations Unauthorized access to the write-able objects could cause a denial of service and/or widespread network disturbance. Hence, the support for SET operations in a non-secure environment without proper protection can have a negative effect on network operations. These are the tables and objects and their sensitivity/vulnerability: o ancpNasAdjacencyTimer Unauthorized changes to ANCP adjacency timer, like changing the adjacency timer to a very small value will increase the adjacency protocol messages generated and increase traffic on the NAS port, this could impact other traffic on the NAS. o ancpNasIfEnable Unauthorized changes to ancpNasIfEnable can result in adverse operational effect by enabling ANCP when that was supposed to be disabled, or service being made un-available to legitimate users. o ancpNasIfNeighbourName, ancpNasIfID Unauthorized changes to ancpNasIfNeighbourName and ancpNasIfID can result in a spurious ANCP neighbor (AN) being added or an actual neighbor being removed disrupting all ANCP traffic from than AN. o ancpNasIfClientID Unauthorized changes to ancpNasIfClientID could result in spurious subscribers being added or legitimate subscribers being removed. Also ancpNasIfClientID being a unique identity of a port, a change to any object may also cause service disruption. It is recommended that the implementers consider the security features as provided by the SNMPv3 framework (see [RFC3410] , section 8), including full support for the SNMPv3 cryptographic mechanisms (for authentication and privacy). Further, deployment of SNMP versions prior to SNMPv3 is NOT RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to enable cryptographic security. It is then a customer/operator responsibility to ensure that the SNMP entity giving access to an instance of this MIB module is properly configured to give access to the objects only to those principals (users) that have legitimate rights to indeed GET or SET (change/ create/delete) them.
