66 Switch Feature Overview
For information about Auto Install, see "DHCP and USB Auto-
Configuration" on page 557.
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 577.
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 487.
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.
