you commit them to activate the configuration. The start transaction command applies only to the current session. Changing the configuration mode of the current session to the Transaction-Based Configuration mode does not affect the configuration mode of other CLI sessions. ● After you explicitly enter the commit command to save changes to the candidate configuration, the session switches back to the default behavior of automatically saving the configuration changes to the running configuration. ● When a session terminates while in the Transaction-Based Configuration mode, and you have not entered the commit command, the changes are maintained in the candidate configuration. You can start a new Transaction-Based Configuration mode session and continue with the remaining configuration changes. ● All sessions in Transaction-Based Configuration mode update the same candidate configuration. When you use the commit command on any session in Transaction-Based Configuration mode or you make configuration changes on any session in Non-Transaction-Based mode, you also commit the changes made to the candidate configuration in all other sessions running in the transaction-based configuration mode. This implies that inconsistent configuration changes may be applied to the running configuration. Dell EMC recommends only making configuration changes on a single CLI session at a time. ● When you enter the lock command in a CLI session, configuration changes are disabled on all other sessions, whether they are in Transaction-Based Configuration mode or Non-Transaction-Based Configuration mode. For more information, see Candidate configuration. CLI command hierarchy CLI commands are organized in a hierarchy. Commands that perform a similar function are grouped together under the same level of hierarchy. For example, all commands that display information about the system and the system software are grouped under the show system command, and all commands that display information about the routing table are grouped under the show ip route command. To move directly to EXEC mode from any sub-mode, enter the end command. To move up one command mode, enter the exit command. CONFIGURATION mode When you initially log in to OS10, you are placed in EXEC mode. To access CONFIGURATION mode, enter the configure terminal command. Use CONFIGURATION mode to manage interfaces, protocols, and features. OS10# configure terminal OS10(config)# Interface mode is a sub-mode of CONFIGURATION mode. In Interface mode, you configure Layer 2 (L2) and Layer 3 (L3) protocols, and IPv4 and IPv6 services on an interface: ● Physical interfaces include the Management interface and Ethernet ports. ● Logical interfaces include Loopback, port-channel, and virtual local area networks (VLANs). From CONFIGURATION mode, you can also configure L2 and L3 protocols with a specific protocol-configuration mode, such as Spanning-Tree Protocol (STP) or Border Gateway Protocol (BGP). CLI Basics 55
