Hello Mr. Chen Jian,
You say that "...the bearer may not be a interface entry of Iftable" but
this statement is incorrect.
Bearer channels are considered as virtual interfaces and have been
allocated ifType values by IANA. E.g., the "Interleave" [=124] and "Fast"
[=125] ifType values are allocated by IANA for ADSL bearer channels as you
can learn in RFC2662.
In adsl2ChannelStatusTable the first key is the ifIndex of the bearer
channel. This is a direct addressing of the bearer channel layer. We
however did not asked for a new ifType value. Instead, we recommended on
using either one of the two values mentioned above or the ifType value
"Channel" [=70] for the ifIndex of the ADSL/2/2plus bearer channels.
Addressing a specific channel STATUS is an operation we identified as a
necessity. This does not contradict the way we CONFIGURE the line.
The configuration template is a complete structure, containing the details
for all layers, line level and channel/Data-Path level. The template is
associated with the whole line and there's is no need to attach a profile
per channel. So, we actually use for this operation the ifIndex of the
line.
Last but not least. You must implement the rows in the ifTable for the
ADSL2 channels because this is MANDATORY. This is not a new requirement in
our document. E.g., this is already in RFC2662. Also, in case the bearer
channel is an ATM interface then the RFC2515 assumes that the ATM interface
has a matching row in the ifTable.

Hello Menachem Dodge,
The indexes of the adsl2ChannelStatusTable are 'ifindex' &
'adsl2ChStatusUnit ' in the MIB draft.
It seems the 'ifindex' stand for index of frame bearer of TPS-TC layer in
this table. I think bearer
channels are contained in a physical line.The physical line can be a entry
of Iftable and the bearer
may not be a interface entry of Iftable.
In the Profile section, we can only bind a Template which contained all
bearer
channel profiles to a xDSL line. The operation of bind a channel profile
to a bearer channel is
unavailable. Thus, the minimum interface may be a physical xDSL line.
So, I suggest the index of the adsl2ChannelStatusTable add a node
adsl2ChStatusChIndex(1-4).
The 'ifindex' of the table means a physical line.
There is another reason for this. If a bearer channel is a interface of
IfTable, we must implement 2-5
interface instances in IfTable of one physical line. I think it is not
necessay.
Best Rgds,
Chen Jian
