Juniper路由器接口命名规则

zhouyi

　　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:
　　[1] at-3/0/0.0
　　[1] at-3/1/0.0
　　[1] at-3/2/0.0
　　[1] 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:
　　[1] t3-2/2/0:0
　　[1] t3-2/2/0:1
　　[1] t3-2/2/0:2
　　[1] t3-2/2/0:3
　　[1] t3-2/2/0:4
　　[1] t3-2/2/0:5
　　[1] t3-2/2/0:6
　　[1] t3-2/2/0:7
　　[1] t3-2/2/0:8
　　[1] t3-2/2/0:9
　　[1] t3-2/2/0:10
　　[1] t3-2/2/0:11
