NOTE: Automatic migration of the startup configuration to the next version of firmware from the current and previous versions of firmware is supported; the syntax is automatically updated when it is read into the running-config. Check the release notes to determine if any parts of the configuration cannot be migrated. Save the running-config to maintain the updated syntax. Migration of configuration is not assured on a firmware downgrade. When upgrading or downgrading firmware, check the configuration to ensure that it implements the desired configuration. Meta-configuration data (stack-port and slot configuration) is always reset to the defaults on a downgrade on each stack unit. As an example, Ethernet ports configured as stacking ports default back to Ethernet mode on a downgrade. Migration of configuration information is never assured when errors are shown while the system is booting. Although the errored lines are displayed, commands that enter a sub-configuration mode followed by an exit command cause the CLI to exit Global Configuration mode, and subsequent configuration commands are ignored. Always hand-edit the startup-config if errors are shown on the screen during bootup. For information about Auto Install, see "DHCP and USB AutoConfiguration" on page 575. sFlow sFlow is the standard for monitoring high-speed switched and routed networks. sFlow technology is built into network equipment and gives complete visibility into network activity, enabling effective management and control of network resources. The Dell EMC Networking N-Series switches support sFlow version 5. For information about configuring managing sFlow settings, see "Monitoring Switch Traffic" on page 595. SNMP Alarms and Trap Logs The system logs events with severity codes and timestamps. The events are sent as SNMP traps to a trap recipient list. For information about configuring SNMP traps and alarms, see "SNMP" on page 505. 64 Switch Feature Overview
