Device-Level Packet Loss Measurement
Device-level packet loss measurement includes the following scenarios:
- Statistics collection on a direct link: collects statistics on lost packets over the link between two directly connected devices.
- Statistics collection on a device: collects statistics on lost packets on all X series cards of a device.
Packet Loss Measurement on a Direct Link
In Figure 5-5, the link between directly connected devices conforms to the packet conservation rule. For example, after packet loss measurement is enabled for the direct link between Switch_1 and Switch_2, you can obtain the loss ratio of packets sent from Switch_1 to Switch_2, or from Switch_2 to Switch_1.
Packet Loss Measurement on a Device
In Figure 5-6, the device conforms to the packet conservation rule. For example, after the packet loss measurement is enabled for Switch, you can obtain the loss ratio of packets sent and received by Switch.
