port Ethernet 1⼀0⼀2 是什么意思？

以太网端口的端口编号规则。

在网络技术中，端口(Port)大致有两种意思：一是物理意义上的端口，比如，ADSL Modem、集线器、交换机、路由器用于连接其他网络设备的接口，如RJ-45端口、SC端口等等；二是逻辑意义上的端口，一般是指TCP/IP协议中的端口，端口号的范围从0到65535，比如用于浏览网页服务的80端口，用于FTP服务的21端口等等。

扩展资料：

常用的保留TCP端口号有：

HTTP 80，FTP 20/21，Telnet 23，SMTP 25，DNS 53等。

常用的保留UDP端口号有：

DNS 53，BootP 67（server）/ 68（client），TFTP 69，SNMP 161等。

每个TCP报文头部都包含源端口号（source port）和目的端口号（destination port），用于标识和区分源端设备和目的端设备的应用进程。

基本是这样进入配置模式sys方法11．创建（进入）VLAN10，将E1/0/1加入到VLAN10
[SwitchA]vlan 10
[SwitchA-vlan10]port Ethernet 1/0/12．创建（进入）VLAN20，将E1/0/2加入到VLAN20
[SwitchA]vlan 20
[SwitchA-vlan20]port Ethernet 1/0/2方法21．进入以太网端口E1/0/1的配置视图
[SwitchA]interface Ethernet 1/0/12．配置端口E1/0/1的PVID为10
[SwitchA-Ethernet1/0/1]port access vlan 103．进入以太网端口E1/0/1的配置视图
[SwitchA]interface Ethernet 0/24．配置端口E1/0/2的PVID为20
[SwitchA-Ethernet1/0/2]port access vlan 20一下是一台我配置过的3600#

以太网端口的端口编号规则
本系列交换机的端口均采用3位编号方式：interface type A/B/C。
l A：IRF中成员设备的编号，若未形成IRF，其取值为1。
l B：设备上的槽位号。取值为0，表示设备上固有端口所在的槽位；取值为1，表示接口模块扩展卡1上端口所在的槽位；取值为2，表示接口模块扩展卡2上端口所在的槽位。
l C：某槽位上的端口编号
