Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Broadband

13、 Radio Access Networks (BRAN). The present document gives guidelines for network management of HIPERLAN Type 2 (HIPERLAN/2) devices and defines a HIPERLAN/2 SNMP MIB. Introduction The present document is organized in the following way: Clause 4 describes some general preconditions for the MIB defini

14、tion; Clause 5 describes the W2 SNMP MIB; Annexes A, B, C, and D contain the MIB definitions (ASN.l). TR 101 683 i contains an overall description of the HIPERLAN/2 system. The Physical (PHY) layer is described in 2, the Data Link Control (DLC) layer is described in 3, the Radio Link Control (RLC) s

15、ublayer is described in 4, and the Convergence (CL) layers for Ethernet and ATM UNI are described in 5, 6, 7, and SI. ETSI 5 ETSI TS 1 O1 762 V1.l.l (2000-1 O) 1 Scope The purpose of the present document is to provide a common view of HIPERLAN Type 2 (W2) devices from different vendors for basic net

16、work monitoring and network control. This is achieved by defining a W2 SNMP MIB to optionally be included in W2 devices. For network monitoring basic performance and fault monitoring is covered. A basic set of configuration parameters is defined for network control. Systems management like device se

17、tup, software upgrade and also the manager side for network management is out of the scope of the present document. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present documen t.

The purpose of defining a MIB and related principles is to provide a common v

33、iew to the human network manager of W2 devices from different vendors. Basic performance and fault monitoring is covered for network monitoring. A basic set of configuration parameters is defined for network control. Systems management like device setup and software upgrade and also the manager side

34、 for network management are considered to be vendor specific and are not described in the present document. Vendor specific additions to the W2 MIB can be placed in vendor specific MIBs. It is assumed that each W2 device with SNMP support besides the W2 MIB contains at least parts of the Internet st

35、andard MIB, MIB-II. 4.1 4.2 Basic Principles SNMP network management requires an IP core network. SNMP often implies a corporate (business) environment. Centralized mode (see 3) is covered. In the future direct mode (see 3) may be covered. The W2 SNMP MIB is defined in the present document for the A

36、P. In the future it may be adapted to any managed W2 device by excluding or adding groups and single objects. SMIv2 (Structure of Management Information) is used for the definition of the W2 MIB. An easy transformation to SMIv1 (and SNMPv1) is provided for so a SNMPv1 manager can be used. For more i

37、nformation on SMI see 5.1. SNMPv3 is recommended for security reasons, but SNMPv3 is not mandatory. For more information on security see 5.1 and 5.2. Management of MT In a corporate network the MTs (PCs) are normally not monitored via SNMP because of the large number of devices. In a W2 environment

38、the mobility of the MTs adds extra complexity. The APs view of the associated MTs is included in the W2 MIB located in the AP. This can be the start for trouble shooting MT related problems. 4.3 Mapping of the H/2 Radio Interace on the Interace Table of MIB-II (informative) The interface table (ifab

39、le) of the standard Internet MIB MIB-II provides information for understanding of how the network interfaces of a device are performing. All types of managed network devices support the interface table of MIB-II. An AP normally supports interface entries for the core network interface and the W2 rad

40、io interface. Characteristics of the W2 radio interface are mapped on an interface entry of the interface table of MIB-II. This makes the W2 device look like any network device to the network manager. Different methods can be used when mapping the W2 radio interface on the ifable of MIB-II. The mapp

41、ing can be done according to RFC 1213 25 or via an extended ifable as described in RFC 2233 26. If the extended ifable is used it is possible to define interface entries for supported CLs besides the W2 interface entry. The order of the interfaces can be defined e.g. indicating that a CL interface i

42、s on top of the W2 interface. Table 1 proposes a mapping for an AP according to RFC 1213 25. Some comments: The layer described in ifable is DLC. Upper layer is CL. The interface to and from the upper layer is DLC-U-SAP, see DLC 3. Lower layer is PHY 2. ETSI 8 ETSI TS 1 O1 762 V1.l.l (2000-1 O) 0 Pa

43、cket in RFC 1213 25 means here a UDCH, UMCH, or UBCH message (see 3). From ifspeed, ifinoctets, and ifoutoctets it should be possible to calculate the utilization of the W2 interface. Just counting the data octets does not tell the utilization because of the link adaptation. Example: In a cell, ther

44、e is a single MT near the AP constantly using a data rate of 5Mbids. The MT is moved to the cell border still using a data rate of 5 Mbids. The utilization of the W2 interface of the AP is now perhaps 5 times larger than before. This is the reason why ifinoctects and ifoutoctets in Table 1 are provi

45、ded as normalized octets. A normalized octet represents a constant portion of the MAC frame, see clause 4.4. ETSI 9 ETSI TS 1 O1 762 V1.l.l (2000-1 O) Object if Descr NOTE: ifinoctets and ifoutoctets is not showing the data traffic through the AP. The traffic can be estimated from other attributes e
