Format for dsl-forum-1 Keyword

When you specify the radius remote-circuit-id-format command with the dsl-forum-1 keyword, the router appends the agent-circuit-id suboption value to an interface specifier that is consistent with the recommended format in the DSL Forum Technical Report (TR)-101—Migration to Ethernet-Based DSL Aggregation (April 2006).

The format of the PPPoE remote circuit ID when you use the dsl-forum-1 keyword is as follows:

dslForum1InterfaceSpecifier#agent-circuit-id

where:

• dslForum1InterfaceSpecifier is the interface specifier in dsl-forum-1 format
• # is the default delimiter character
• agent-circuit-id is the agent-circuit-id suboption (suboption 1) of the PPPoE intermediate agent tags sent from the DSLAM

If the DSLAM transmits empty data for agent-circuit-id, the router appends the value 0/0/0/0/0/0 to dslForum1InterfaceSpecifier.

To obtain the value for dslForum1InterfaceSpecifier, the router translates an internally generated interface specifier into the format for the dsl-forum-1 keyword, using the following conventions:

• The dsl-forum-1 format for ATM interfaces is atm slot/adapter/port:vpi.vci
• The dsl-forum-1 format for Ethernet interfaces is eth slot/adapter/port:svlanId.vlanId
• For the E120 router or the E320 router, the router uses the actual adapter value (0 or 1) in the dsl-forum-1 format. For ERX-14xx models, ERX-7xx models, and the ERX-310 router, which do not support an adapter value, the router sets the adapter value to 0 (zero).
• For Ethernet interfaces that use VLANs but do not use S-VLANs, the router sets the svlanId value to 4096 and uses the actual vlanId value in the dsl-forum-1 format.
• For Ethernet interfaces that use neither S-VLANs nor VLANs, the router sets both the svlanId value and the vlanId value to 4096 in the dsl-forum-1 format.
• The router ignores subinterface values for ATM and Ethernet interfaces in the translated dsl-forum-1 format.

  Note: The format of the interface specifier that the router generates internally is different from the interface specifier format that you use to configure interfaces on the router. For information about the interface types and specifiers to use when configuring interfaces on E-series routers, see Interface Types and Specifiers in JUNOSe Command Reference Guide.
