Juniper JUNOSE 11.1.X - LINK LAYER CONFIGURATION 4-7-2010, Configuration Manual

Page: 414 / 774

■
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 382 provides several examples of how the router uses the
conventions described in “Format for dsl-forum-1 Keyword” on page 381 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.
