路由器和交换机的接⼝命名含义
路由器和交换机的接⼝命名含义
The notation is denoting that there are multiple NIC interfaces on the router in the diagram and it's making reference to this.
F0/0 - interface #1
F0/1 - interface #2
NOTE: The F indicates that the NIC/port is most likely a Fast Ethernet type of connection.

shows them as well. Here's the referenced as Fa 0/1, which I believe is the more typical notation.
The other interesting take away is that the notation may sometimes include a 3rd digit to denote that the interface being referenced is not built into the Motherboard of the networking gear. The above diagram shows some examples of this, ie. T1 1/0/1. NOTE: The 3rd digit prefixes, and indicates which "slot" on the Motherboard a port is coming from.
Again the Cisco reference describes the slots like so:
I was also able to dig up this reference: which describes the reference of F0/0 like so. Take note that there are 2 types of situations:
Fixed interface ries router
Modular interface ries router
This notation was originally ud for fixed types of routers:
In fixed interface ries router, the interface nomenclature is type slot_#/ port_#.
hurry是什么意思But with the advent of modular routers, that did not denote which addon card (WIC) was being referenced. So the notation was expanded: New naming convention only for WIC slots (WAN Interface Card) is type slot_#/subslot_#/ port_#.
Ports installed directly on chassis still u classic convention that is type slot_#/ port_#.
Incidentally that same site had this table which describes the F0/0 notation like this:
Additional arches did turn up this URL: which had the types of ports listed:
Aux port: This auxiliary port is ud to connect a modem to the router, which can then be ud to remotely modify the少儿英语动画片下载
configuration on the router.
Attachment Unit Interface (AUI) port: Before the WIC became a standard for providing expansion through an add-on port,
the AUI allowed transceivers to be ud, providing you with the ability to add various types of network connections, such
as fiber or copper Ethernet connections.
Serial: Connects a modem or other rial device to allow a WAN network interface to be ud on the router.
Ethernet/Fast Ethernet/Gigabit Ethernet: Standard network interfaces ud to connect different network gments.
Console: Serial configuration port for command-line access to router management and configuration. Refer to Figure 3-1
to e the console port.
WAN Interface Card (WIC) port: Becau a wide variety of WAN connectivity options are available (for example, T1, ISDN,
ADSL), you can u this port to add different interfaces to a standard router.
Hardware WAN Interface Card (HWIC) port: With the integration of rvices into routers, the WIC interface became too
limiting. The HWIC interface was created to support a wider variety of hardware expansion options, such as switches and
rvice cards. This port is backward compatible with most older WIC hardware.
As well as this URL: :
Ethernet - Ethernet is typically Ethernet IEEE 802.3 standard bad physical interface, which operates at 10 Mbps speed.
The media standard ud is 10BaT.
Fast Ethernet - Fast Ethernet is typically Ethernet IEEE 802.3u standard bad physical interface which operates at 100
Mbps speed. The media standard ud is 100BaT.
Gigabit Ethernet - Gigabit Ethernet is typically Ethernet IEEE 802.3ab standard bad physical interface which operates at
1000 Mbps speed. The media standard ud is 1000BASE-T
Serial - Serial interfaces are typically ud for WAN connections from ISP (Internet Service Providers) for connectivity
types like Frame Relay, T1, T3, etc.
FDDI Fiber Distributed Data Interface - FDDI networks operates at 100 Mbps speed and us a token-passing mechanism
to prevent collisions.
Token Ring - Token Ring interfaces can operate at either 4 Mbps or 16 Mbps. In Token Ring networks a token is pasd
around the network (configured in ring topology), allowing the owner of the token to transmit a frame, to avoid
collision.Token Ring networks vanished from networking industry long way back. New Cisco routers do not have a Token
Ring interface.
Note: Only 10Mbps Ethernet interface has a name "Ethernet" in a Cisco Router. A 100Mbps Ethernet interface is called a
"FastEthernet" interface and a 1000Mbps Ethernet interface is called a "GigabitEthernet" interface.
That last bit is a bit more telling. Since Ethernet would historically been ud for 10MBps interfaces, the "F" in my "F0/0" & "F0/1" diagram would em to imply that the interface is a FastEthernet capable connection (10/100MBps).
However, more recently, Ethernet can also be ud interchangeably on Gigabit Ethernet as well as 10G Ethernet ports, so you need to pay special attention to the actual equipment that's been referenced by a diagram.

该符号表⽰图中的路由器上有多个NIC接⼝，并且正在对此进⾏引⽤。
F0 / 0-接⼝＃1
F0 / 1-接⼝＃2
注： F表⽰NIC /端⼝很可能是快速以太⽹类型的连接。
显⽰了它们。这⾥称为Fa 0/1，我相信这是更典型的表⽰法。
另⼀个有趣的收获是，该符号有时可能包含第三个数字，以表⽰所引⽤的接⼝未内置在⽹络设备的主板中。上图显⽰了⼀些⽰例。T1

1/0/1。注意：第3位数字前缀，表⽰端⼝来⾃主板上的哪个“插槽”。
再次，Cisco参考描述了这些插槽，如下所⽰：
我也能够找到该参考⽂献：像这样描述了F0 / 0的参考⽂献。请注意，有两种情况：
固定接⼝系列路由器
模块化接⼝系列路由器
此符号最初⽤于固定类型的路由器：
美食祈祷恋爱
在固定接⼝系列路由器中，接⼝名称为类型槽位 _＃/ 端⼝_＃。
但是随着模块化路由器的问世，这并不表⽰正在引⽤哪个附加卡（WIC）。因此，表⽰法进⾏了扩展：
仅对于WIC插槽（WAN接⼝卡）的新命名约定是类型槽位 _＃/ ⼦槽位 _＃/ 端⼝_＃。
直接安装在机箱上的端⼝仍为类型槽位 _＃/ 端⼝_＃的经典约定。
顺便说⼀句，同⼀站点具有此表，该表描述了这样的F0 / 0表⽰法：
其他搜索确实打开了以下URL：，其中列出了以下类型的端⼝：
辅助端⼝：此辅助端⼝⽤于将调制解调器连接到路由器，然后可⽤于远程修改路由器上的配置。
附件单元接⼝（AUI）端⼝：在WIC成为通过附加端⼝提供扩展的标准之前，AUI允许使⽤收发器，从⽽使您能够添加各种

串⾏：连接调制解调器或其他串⾏设备，以允许在路由器上使⽤WAN⽹络接⼝。
us ady8 info以太⽹/快速以太⽹/千兆以太⽹：⽤于连接不同⽹段的标准⽹络接⼝。
控制台：串⾏配置端⼝，⽤于命令⾏访问路由器管理和配置。请参阅图3-1，查看控制台端⼝。
WAN接⼝卡（WIC）端⼝：由于有多种WAN连接选项可⽤（例如T1，ISDN，ADSL），因此您可以使⽤此端⼝向标准路
由器添加不同的接⼝。
硬件WAN接⼝卡（HWIC）端⼝：随着将服务集成到路由器中，WIC接⼝变得过于局限。HWIC接⼝

以及以下URL：：

串⾏ -串⾏接⼝通常⽤于ISP（Internet服务提供商）的WAN连接，以实现帧中继，T1，T3等连接类型。
莫大的意思FDDI光纤分布式数据接⼝ -FDDI⽹络以100 Mbps的速度运⾏，并使⽤令牌传递机制来防⽌冲突。
令牌环 -令牌环接⼝可以以4 Mbps或16 Mbps的速度运⾏。在令牌环⽹络中，令牌在⽹络中传递（以环形拓扑配置），从⽽
令牌的所有者可以传输帧以避免冲突。令牌环⽹络从⽹络⾏业中消失了很长时间。新的Cisco路由器没有令牌环接⼝。
注意：在Cisco路由器中，只有10Mbps以太⽹接⼝的名称为“以太⽹”。100Mbps以太⽹接⼝称为“ FastEthernet”接⼝，⽽
unusualness1000Mbps以太⽹接⼝称为“ GigabitEthernet”接⼝。
最后⼀点更具说服⼒。由于以太⽹过去⼀直⽤于10MBps接⼝，因此在我的“ F0 / 0”和“ F0 / 1”图中，“ F”似乎暗⽰该接⼝是⽀持FastEthernet 的连接（10 / 100MBps）。
但是，最近，以太⽹也可以在千兆位以太⽹和10G以太⽹端⼝上互换使⽤，因此您需要特别注意图中引⽤的实际设备。
