Numbering Scheme
When configuring or managing an interface, you must know the numbering scheme
for identifying an interface. The numbering scheme depends on the type of E-series
router that you have.
ERX-7xx Models, ERX-14xx Models, and the ERX-310 Router
Use the slot/port [ .subinterface ] format to identify Ethernet interfaces and
subinterfaces.
■
slot —Number of the slot in which the line module resides in the chassis.
In ERX-7xx models, line module slots are numbered 2-6; slots 0 and 1 are
reserved for SRP modules. In ERX-14xx models, line module slots are numbered
0–5 and 8–13; slots 6 and 7 are reserved for SRP modules. In an ERX-310 router,
line module slots are numbered 1–2; slot 0 is reserved for the SRP module.
■
port —Number of the port on the I/O module.
On the OC3-2 GE APS I/O module, you can configure only a Gigabit Ethernet
interface in port 2; ports 0 and 1 are reserved for OC3/STM1 ATM interfaces.
■
subinterface —Subinterface number of the protocol or VLAN subinterface.
For information about installing line modules and I/O modules in ERX routers, see
ERX Hardware Guide, Chapter 4, Installing Modules .
E120 Router and E320 Router
Use the slot/adapter/port [.subinterface] format to identify Ethernet interfaces and
subinterfaces.
