Table 21: Interface Specifier Format Examples for dsl-forum-1 Keyword

Interface Example
ATM 1483 subinterface on
slot 2, port 0, subinterface 1
with VPI 100 and VCI 101
ATM 1483 subinterface on
slot 3, adapter 1, port 7,
subinterface 6 with VPI 200
and VCI 201
Gigabit Ethernet interface on
slot 2, port 0 with no VLAN
or S-VLAN subinterfaces
378
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 or the E320 routers, the router uses the actual adapter value (0 or 1) in
the dsl-forum-1 format. For ERX14xx models, ERX7xx models, and the ERX310 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.
Format Examples for dsl-forum-1 Keyword
Table 21 on page 378 provides several examples of how the router uses the conventions
described in "Format for dsl-forum-1 Keyword" on page 377 to translate internally generated
interface specifiers into the format of the dslForum1InterfaceSpecifier value. The examples
in the table use adapter 1 for interfaces on an E120 or E320 router, and adapter 0 (no
adapter value) for interfaces on ERX14xx models, ERX7xx models, and the ERX310 router.
