Interfaces Group (RFC 1573)
The evolution of the Interfaces Group of MIB II (RFC 1573 converted to
SNMP v1) consists of an object indicating the number of interfaces supported by
the DSL router and an interface table containing an entry for each interface.
Refer to Table C-3 for the objects supported for the DSL and Ethernet interfaces.
The Interface Stack Group table does not apply, but is required for MIB
compliance. One row will be displayed with ifStackHigherLayer=0 and
ifStackLowerLayer=0. The ifStackStatus=2 (enumerated value for notInService)
and is read-only. The Interface Test Table and the Generic Receive Address
Table are not supported.
Table C-3. Interfaces Group Objects (1 of 2)
Object Description Setting/Contents
ifNumber
( interfaces 1) Supported as specified in
the Evolution MIB. Specifies the number of interfaces for this unit in the ifTable.
ifIndex
( ifEntry 1) Provides the index into the
interface table ( ifTable )
and to other MIB tables.
ifIndex calculation:
(Slot # * 1000 + local port)
* 1000 + remote ifIndex
Remote ifIndex (DSL router ifIndex) and Interface:
H 0 – DSL router.
H 1 – Ethernet interface.
H 2 – DSL network interface.
H noSuchName – Unsupported index entered.
ifDescr
( ifEntry 2) Supplies text for each
interface:
H DSL interface
Text Strings for each interface:
H “DSL Interface; Card Type (IDSL, RADSL, SDSL); S/W Release:
yy yy yy; H/W Release:zzz; [CCA part number]”
H DSL interface
H Ethernet interface
yy.yy.yy; H/W Release:zzz; [CCA part number]”
H “Ethernet Interface; Card Type (frame format of Type II or SNAP);
S/W Release:
yy.yy.yy; H/W Release:zzz; [CCA part number]”
ifType
( ifEntry 3 ) Identifies the interface type
based on the physical/link
protocol(s). Supported values:
H radsl(95) – Used for RADSL.
H sdsl( 96 ) – Used for SDSL.
H iso88023Csmacd(6 ) – Used for Ethernet.
H idsl( 154 ) – Used for IDSL.
ifMtu
( ifEntry 4 ) Identifies the largest
datagram that can be sent
or received on an
interface. Integer.
ifSpeed
( ifEntry 5 ) Provides the interface’s
current bandwidth in bits
per second (bps). H DSL interface – The downstream rate of the DSL interface once
trained, or zero if not trained.
H Ethernet interface – 10240000 bps (for 10 MB operation) or
102400000 (for 100 MB operation).
ifPhysAddress
( ifEntry 6 ) Identifies the physical
address for the interface. H DSL interface – The MAC address when operating in 1483
Bridged mode.
H Ethernet interface – The MAC address.
ifAdminStatus
( ifEntry 7 ) Supported as read-only. H up(1) – Always displays as up.
