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 S6000 | Configuration Guide for the S6000 System 9.90.0 - Page 34

3 Getting Started This chapter describes how you start configuring your system. When you power up the chassis, the system performs a power-on self test (POST) and system then loads the Dell Networking Operating System. Boot messages scroll up the terminal window during this process. No user - Dell PowerSwitch S6000 | Configuration Guide for the S6000 System 9.90.0 - Page 43

Figure 19. BGP Routers in Full Mesh The number of BGP speakers each BGP peer must maintain increases exponentially. Network management quickly becomes impossible. Sessions and Peers When two routers communicate using the BGP protocol, a BGP session is started. The two end-points of that session are - Dell PowerSwitch S6000 | Configuration Guide for the S6000 System 9.90.0 - Page 154
State Idle Connect Description BGP initializes all resources, refuses all inbound BGP connection attempts, and initiates a TCP connection to the peer. In this state the router waits for the TCP connection to complete, transitioning to the OpenSent state if successful. If that transition is not - Dell PowerSwitch S6000 | Configuration Guide for the S6000 System 9.90.0 - Page 155
