Therefore this object will be set to the value of 127.
4. Evolution of the Interfaces Group of MIB-II (RFC 2863)
The interfaces group consists of an object indicating the number of interfaces supported by 
the unit and an interface table containing an entry for each interface in the GranDSLAM 
R3.2. Since RFC 2863 is an SNMPv2 MIB it will be converted to SNMPv1 for support by 
the GranDSLAM R3.2. There will be entries for WAN interfaces, ATM cell interfaces, an 
AAL5 interface, management interfaces and DSL interfaces.
4.1
“ifNumber” Object (interfaces 1) 
ifNumber will be supported as specified in the Evolution MIB and will specify the number 
of rows in the ifTable for this particular device.
4.1.1
“ifIndex” Object (ifEntry 1) 
This object provides the index into the ifTable and typically into tables in other MIBs also. 
A unique value, greater than zero, for each interface or interface sublayer in the managed 
system. It is recommended that values be assigned contiguously starting from 1. The value 
for each interface sublayer must remain constant at least from one re-initialization of the 
entity’s network management system to the next re-initialization. 
4.1.1.1
ifIndex scheme
This section introduces the ifIndex scheme to be used in the GranDSLAM R3.2 product. It 
describes the interfaces to be managed as specified in the system requirements along with 
their corresponding ifIndex assigned.  The assignment of the values to the ifIndex in the 
product is static and maintained across power cycles and software upgrades. The first 
column in 
, is the Interface description. The 
second column corresponds to the layer in the stack where this interface fits (It does not 
necessary match the layer in the OSI model). The third column is the  number of this 
interface supported in the current software release. The forth column is the maximum 
number of this interface that is envisioned  in this product.  The fifth  column is the name 
associated with that instance of the interface.
The ‘x’ suffix in some ifName values corresponds to the interface/port number within the 
same chassis.
