IEEE Std 802.16-2001

LOCAL AND METROPOLITAN AREA NETWORKS—PART 16:

11.3 Configuration file encodings

These settings are found in only the configuration file. They shall not be forwarded to the BS in the Registration Request. Type fields and length fields are 1 byte in length.

11.3.1 End-of-data marker

This is a special marker for end of data. It has no length or value fields.

Type

255

11.3.2 Pad configuration setting

This has no length or value fields and is only used following the end of data marker to pad the file to an integral number of 32-bit words.

Type

0

11.3.3 Software upgraded filename

The filename of the software upgrade file for the SS. The filename is a fully qualified directory-path name which is in a format appropriate to the server. There is no requirement that the character string be null terminated; the length field always identifies the end of the string. The file is expected to reside on a TFTP server identified in a configuration setting option defined in 11.4.7.

11.3.4 SNMP write-access control

This object makes it possible to disable SNMP “Set” access to individual Management Information Base (MIB) objects. Each instance of this object controls access to all of the writable MIB objects whose Object ID (OID) prefix matches. This object may be repeated to disable access to any number of MIB objects,

OID prefix plus control flag

 

 

 

where n is the size of the ASN.1 Basic Encoding Rules [ISO 8825] encoding of the OID prefix plus one byte for the control flag.

AIR INTERFACE FOR FIXED BROADBAND WIRELESS ACCESS SYSTEMS

IEEE Std 802.16-2001

The control flag may take the following values:

0- allow write-access

1- disallow write-access

Any OID prefix may be used. The Null OID 0.0 may be used to control access to all MIB objects.

When multiple instances of this object are present and overlap, the longest (most specific) prefix has precedence. Thus, one example might be as follows:

someTable

disallow write-access

 

 

someTable.1.3

allow write-access

 

 

This example disallows access to all objects in some table except for someTable.1.3.

11.3.5 SNMP MIB Object

This object allows arbitrary SNMP MIB objects to be Set via the TFTP-Registration process,

Type

Value

n

variable binding

 

 

 

where the value is an SNMP VarBind as defined in IETF RFC 1157. The VarBind is encoded in ASN.1 Basic Encoding Rules, just as it would be if part of an SNMP Set request.

The SS shall treat this object as if it were part of an SNMP Set Request with the following caveats:

a)It shall treat the request as fully authorized (it shall not refuse the request for lack of privilege).

b)SNMP Write-Control provisions (see 11.3.4) do not apply.

c)No SNMP response is generated by the SS.

This object may be repeated with different VarBinds to “Set” a number of MIB objects. All such Sets shall be treated as if simultaneous.

Each VarBind shall be limited to 255 bytes.

11.3.6 Software upgrade TFTP server

This object is the IP address of the TFTP server on which the software upgrade file for the SS resides.
