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。

每个以太帧之间都要有帧间隙(Inter Frame Gap),即每发完一个帧后要等待一段时间才能再发另外一个帧,以便让帧接收者对接收的帧做必要的处理(如调整缓存的指针、更新计数、通知对报文进行处理等等)。在以太网标准中规定最小帧间隙是12个字节,其数据为全1。对于个别的接口,可减少到64(GE)或40比特(10GE),其他的...
In the Consoles group box, navigate to the applicable port's text and enter the appropriate port number, where different from the default port number. Click the corresponding Enabled or Disabled radio button. Note: Telnet Enable/Disable is not supported when authentication is enabled....
GID网络设备:/sys/class/infinband/<device>/ports/<port>/gid_attrs/ndevs/<index> 对一个QP设置RoCE模式(前提是配置好了GID表): 对于RC/UC QP,在从INIT转换到RTR状态时,填充一个地址向量(Address Vector)时,应该为QP的源GID指定硬件端口的GID表索引。这个索引对应的GID类型就被设置为该QP的RoCE类型。
Specify a port range in the form of interface-type interface-number to interface-type interface-number where the end port must be greater than the start port. agg-id: Source or destination aggregation group ID. If it is a source aggregation group, the port with minimum port number is the...

执行命令interfacegigabitethernetinterface-number,进入指定以太网接口的视图。 执行命令port-mode{10ge|1ge},使能以太网GE接口的工作速率模式。 缺省情况下,GE接口的工作速率模式为非强制模式。 检查配置结果 以太网接口参数配置成功后,您可以查看到以太网接口的状态、MTU等信息。
