Hi All, As described “802.16_2004_TGF.pdf, draft2, section 9.3.2.2”
we decided to manage wireless man “BS Sectors” as network interface.
As such there is one row defined in the interface table (ifTable) per “BS
Sector” along with required attributes e.g. ifType (propBWAp2Mp), IfPhysAddress
(Mac Address of BS Sector) etc. Two questions arise: 1. Can anybody think of the scenario where
the Mac Address of “BS Sector” would be actually used? 2. Can the ifPhysAddress be filled with zero
length octet string as suggest the description of this object in the IF-MIB
(see extract below) if standard doesn’t define the use of it? Unlike SS Mac Address the Mac Address of BS (Sector) is not defined
in the standard 802.16-2004 at all. The BS Mac Address is mentioned in the
802.16e/D5a in the context of Neighbor advertisement message. But in this
context it is not sure what Mac Address the document refers to (what type of interface
in the interface table). Nevertheless the issue is with 802.16f MIB, which is
designed for fixed operation. Extract form IF-MIB: “ ifPhysAddress OBJECT-TYPE
SYNTAX PhysAddress MAX-ACCESS read-only STATUS
current DESCRIPTION
"The interface's address at its protocol sub-layer. For
example, for an 802.x interface, this object normally
contains a MAC address. The interface's media-specific MIB
must define the bit and byte ordering and the format of the
value of this object. For interfaces which do not have such
an address (e.g., a serial line), this object should contain
an octet string of zero length." ::= { ifEntry 6 } ” Regards, Krzysztof Dudzinski Airspan Networks |
