Juniper路由器接口命名规则
首先接口分为2类
Permanent Interfaces,fxp0用于管理,类似Cisco loopback接口和fxp1用于内部链接RE和PFE
Transient Interfaces.除fxp0/1之外的都是Transient Interfaces,
Interface Naming Structure of Transient Interfaces
media_type-fpc/pic/port.unit
1.media_type
A two-character designator that uniquely> cisco没有的东西,指的是用2个字母来描述接口的类型,如:
ae
Aggregated Ethernet interface
as
Aggregated SONET/SDH interface
at
Asynchronous Transfer Mode (ATM) interface
ds
DS0 interface (including Multichannelized DS-3 interfaces)
e1
E1 interface (including Channelized STM-1 to E1 interfaces)
e3
E3 interface
es
Encryption interface
fe
Fast Ethernet interface
fxp
Management and Internal Ethernet interfaces
ge
Gigabit Ethernet interface
gr
Generic Route Encapsulation tunnel interface
ip
IP-over-IP encapsulation tunnel interface
lo
Loopback interface
so
SONET/SDH interface
t1
T1 interface (including Channelized DS-3)
t3
T3 interface (including Channelized OC-12 interfaces)
2.fpc –类似思科的sip母板
The physical slot in the chassis where the interface is located

3.pic-类似思科的spa子卡
The slot on the FPC that contains the interface

4.port 这个没问题了,就是spa上的接口.
The location on the PIC where the interface port is located

5.Unit子接口.
The logical portion of the interface that contains properties, such as an IP address
Let’s examine each of these interface portions in more detail.
Suppose a router has two OC-3 PICs in slots 0 and 1 on an FPC
in slot 1. Each of the PICs contains two ports. The names of these interfaces are:
so-1/0/0.0
so-1/0/1.0
so-1/1/0.0
so-1/1/1.0
When an FPC in slot 3 contains four OC-12 ATM PICs, the FPC becomes fully populated.
Each PIC supports a single physical port. The interface names when each port has a single log-
ical unit assigned are:
at-3/0/0.0
at-3/1/0.0
at-3/2/0.0
at-3/3/0.0
The OC-48 SONET FPC in an M40 router is an example of a quad-wide PIC. Should this
PIC be installed in slot 6, it appears as PIC slot 0 with a single port 0. The JUNOS software rep-
resentation becomes:
so-6/0/0.0
A channelized OC-12 PIC contains 12 logical DS-3 channels. When installed in PIC slot 2 on
FPC slot 2, the channels are represented as:
t3-2/2/0:0
t3-2/2/0:1
t3-2/2/0:2
t3-2/2/0:3
t3-2/2/0:4
t3-2/2/0:5
t3-2/2/0:6
t3-2/2/0:7
t3-2/2/0:8
t3-2/2/0:9
t3-2/2/0:10
t3-2/2/0:11
