2 Configuration Fundamentals The Dell Networking Operating System (OS) command line interface (CLI) is a text-based interface you can use to configure interfaces and protocols. The CLI is largely the same for each platform except for some commands and command outputs. The CLI is structured in modes - Dell PowerSwitch S4810P | Configuration Guide for the S4810 System 9.80.0 - Page 35

Shared LAG State Tracking Shared LAG state tracking provides the flexibility to bring down a port channel (LAG) based on the operational state of another LAG. At any time, only two LAGs can be a part of a group such that the fate (status) of one LAG depends on the other LAG. As shown in the - Dell PowerSwitch S4810P | Configuration Guide for the S4810 System 9.80.0 - Page 476
As shown in the following illustration, LAGs 1 and 2 are members of a failover group. LAG 1 fails and LAG 2 is brought down after the failure. This effect is logged by Message 1, in which a console message declares both LAGs down at the same time. Figure 60.

Quality of Service (QoS) Quality of service (QoS) is supported on Dell Networking OS. Differentiated service is accomplished by classifying and queuing traffic, and assigning priorities to those queues. Table 57.
