Interfaces Overview

This section contains the following topics:

Network Interface Types

J-series Services Routers support the following network interface types:
E1, Fast Ethernet, serial, T1, and T3.
T3 interfaces, which are also known as DS3 interfaces, are supported
on J6300 Services Routers only.

Interfaces and Interface Naming

The interfaces on a Services Router are used for networking and services. Most
interfaces are configurable, but some internally generated interfaces are not
configurable. Each interface has a unique name that identifies its type and location
and indicates whether it is a physical interface or an optional logical unit created on
a physical interface:
For example,
15 on that interface, and
The parts of an interface name are explained in Table 27.

The name of each interface on the router has the following format, to identify
the physical device that corresponds to a single physical network connector:
type - FPC / PIM / port
Network interfaces that are fractionalized into time slots include a virtual DS0
channel number in the name, preceded by a colon (:):
type - FPC / PIM / port : channel
Each logical interface has an additional logical unit identifier, preceded by a
period (.):
type - FPC / PIM / port :< channel >. logical unit
is the E1 interface on port 0 of FPC 5,
e1-5/0/0
e1-5/0/0:15.0
e1-5/0/0:15
is logical unit 0 on that channel.
