您要查找的是不是：
- packet level logical interface 包级逻辑接口
- Netmon is used to monitor network traffic at the packet level. Netmon用于监视数据包级别的网络通信。
- A subinterface is a logical interface within a physical interface. 子接口是在物理接口上的逻辑接口。
- No IP heartbeat is available to identify logical interface failures. 可以用没有IP心跳来识别逻辑接口失效。
- SVCs do not eliminate all queuing issues, as the flow from the packet level must still be queued to the physical line. SVC没有消除所有的排队问题，因为从包层出来的信息流仍须排队送到物理线路上。
- SVCs do not eliminate all queuing issues,as the flow from the packet level must still be queued to the physical line. SVC没有消除所有的排队问题，因为从包层出来的信息流仍须排队送到物理线路上。
- The changes you see at the packet level will help indicate the success of your tuning with these techniques. 在报文级看到的变化可以帮助展示使用这些技术进行优化之后所取得的成功效果。
- For example, the following mapping stanza will cause ifup to bring up interface eth0 as the home logical interface. 例如,下面这段mapping会让ifup用逻辑接口home来激活接口eth0。
- This warning may also be caused if a network error is introduced at the packet level. 如果在数据包级引入网络错误,也可能引起此警告。
- A subinterface is a logical interface within a physical interface, such as the Fast Ethernet interface on a router. 一个子界面是在一个实体界面(例如：路由器上的高速乙太网路界面)上的逻辑界面。
- Eseutil verifies the page level and Extensible Storage Engine (ESE) level logical integrity of the database but does not verify database integrity at the Information Store level. Eseutil可验证页级别和可扩展存储引擎(ESE)级别的数据库逻辑完整性,但不会验证信息存储级别的数据库完整性。
- A loopback interface, which is a logical interface, can be configured for this purpose. 为了此目的，可组态设定一个逻辑介面的迴路介面。
- In the following it will be important for the reader to understand the difference between a physical interface and a logical interface. 下列内容中,对于读者而言了解物理接口(physical interface)和逻辑接口(logical interface)之间的不同是重要的。
- If no logical interface name is given on the ifup command line then the physical interface name is used as the initial logical interface name. 如果执行ifup的时候没有给定逻辑接口名称,那么物理接口名称就会被用作初始的逻辑接口名称。
- With the growing popularity of Asynchronous Transfer Mode and frame relay services,encrypting data at the packet level is becoming an attractive alternative to the conventional method of securing transactions on a link-by-link basis. 随着异步传输模式（ATM）和帧中继服务的日渐流行（信息）包级上的数据加密正在成为一种链路到链路基础上使交易安全进行的颇有吸引力的常规替代办法。
- The reason is that ifup uses the physical interface name as the default logical interface name and now in our example no eth0 logical interface is defined. 理由是ifup使用物理接口名作为缺省的逻辑接口名,但是现在在我们的例子中,没有关于逻辑接口eth0的定义。
- Thus ifup can be so configured that it brings up a given physical interface as the appropriate logical interface among a set of predefined alternatives. 因此ifup能够被设置为用预设的逻辑接口集合中的一个合适的逻辑接口来激活物理接口。
- AIr is the base protocol of infrared wireless LANs. AIr adopts No Packet Level Acknowledgement Protocol(NoPLACK),Packet Level Acknowledgement Protocol,SW-ARQ in AIrMAC,AIr Link Control,and AIr Link Manage. AIr协议在媒体访问控制 (MAC)、链接控制和链接管理上选择了无包级确认协议 (NoPLACK)、包级确认协议 (PLACK)、停 等自动重传请求协议(SW ARQ)等协议。
- With the growing popularity of Asynchronous Transfer Mode and frame relay services, encrypting data at the packet level is becoming an attractive alternative to the conventional method of securing transactions on a link-by-link basis. 随着异步传输模式（atm）和帧中继服务的日渐流行（信息）包级上的数据加密正在成为一种链路到链路基础上使交易安全进行的颇有吸引力的常规替代办法。
- If single hop radio distance is smaller than sensing range, such Physical layer firing proposals are ideal for LESOP, because there would be no packet level delay incurred in consecutive hops. 若单跳发射距离在感应范围内，该类物理层发射方案将是施行低功耗自组织协议（LESOP）的理想选择，因为该类方案在连跳过程中可以避免分组级时延。
