See ERX Module Guide, Appendix A, Module Protocol Support for information about the
modules that support transparent bridging.
For information about the modules that support transparent bridging on the E120 and
E320 routers:
See E120 and E320 Module Guide, Table 1, Modules and IOAs for detailed module
specifications.
See E120 and E320 Module Guide, Appendix A, IOA Protocol Support for information
about the modules that support transparent bridging.
The configuration task examples in this chapter use the slot/port[.subinterface ] format
to specify the physical interface on which to configure transparent bridging. However,
the interface specifier format that you use depends on the router that you are using.
For ERX7xx models, ERX14xx models, and ERX310 router, use the slot/port[.subinterface
] format. For example, the following command specifies ATM 1483 subinterface 10 on
slot 0, port 1 of an ERX7xx model, ERX14xx model, or ERX310 router.
host1(config)#interface atm 0/1.10
For E120 and E320 routers, use the slot/adapter/port[.subinterface ] format, which includes
an identifier for the bay in which the I/O adapter (IOA) resides. In the software, adapter
0 identifies the right IOA bay (E120 router) and the upper IOA bay (E320 router); adapter
1 identifies the left IOA bay (E120 router) and the lower IOA bay (E320 router). For
example, the following command specifies ATM 1483 subinterface 20 on slot 5, adapter
0, port 0 of an E320 router.
host1(config)#interface atm 5/0/0.20

Before you configure transparent bridging on an E Series router, verify that:
You have correctly installed a line module that supports transparent bridging. For a
list of the line modules that support transparent bridging, see ERX Module Guide,
