Menachem,
The usage of a VPI/VCI is
really dependent on the use case you are considering.
Regarding the use case
access line topology it is optional because there is no strong relation to a
layer 2 parameter if we report the net data rate.
But considering the use
cases OAM (F5 LB for ADSL2/2plus) or line configuration the layer 2 parameter
such as VPI/VCI or VLAN is essential. So I would recommend keeping these layer
2 parameters in the format of the “Access-Loop-Circuit-ID”.

Thomas

Betreff: [ANCP] Layer 2 Parameters
in the Protocol document
Hi,
I have a question regarding the
"Access-Loop-Circuit-ID" as defined in the document "draft-wadhwa-gsmp-l2control-configuration-01.txt".
In the case of an Ethernet based local loop the format is
defined as:
"Access-Node-Identifier eth slot/port[:vlan-id]"
meaning that the vlan-id is optional.
In the case of an ATM based local loop the format is
defined as:
"Access-Node-Identifier atm slot/port:vpi.vci" meaning
that the vpi.vci is mandatory.
I would like this changed to "Access-Node-Identifier
atm slot/port[:vpi.vci]" meaning that the vpi.vci is optional.
This would allow for multiple vpi/vci(s) on the same port
as a message could be sent without the vpi.vci field.

I have a
similar question regarding the "Access-Aggregation-Circuit-ID-ASCII"
as defined in the document "draft-wadhwa-gsmp-l2control-configuration-01.txt".
In the case of an Ethernet based local loop the format is
defined as:
"Access-Node-Identifier eth
slot/port[:inner-vlan-id][:outer-vlan-id]" meaning that the vlan-ids are
optional.
In the case of an ATM based local loop the format is
defined as:
"Access-Node-Identifier atm slot/port:vpi.vci" meaning
that the vpi.vci is mandatory.
I would like this changed to "Access-Node-Identifier
atm slot/port[:vpi.vci]" meaning that the vpi.vci is optional.
Thank
you kindly.
Best
Regards,
Menachem
