Dell M6220 User Configuration Manual page 246

• Simple mode allows the user to create Aggregation Groups where internal
ports and external ports can be configured in a separate broadcast domain.
• Security-related configurations: dot1x, RADIUS, TACACS+ are allowed
when the switch is operating in Simple Mode.
• All other feature configurations from the CLI/Web/SNMP interfaces are
disabled, and the user does not see any commands/pages/MIBs related to
all other regular features that are available in Normal Mode.
• The hashing algorithm in Simple mode is the same as the default hashing
algorithm in Normal mode. In Normal mode, the default hashing is based
on source MAC and destination MAC address. You cannot change the
hash algorithm in Simple mode. Ports that are already a member of a LAG
are external ports that are shown using the show port-aggregator port
summary command. In Simple mode, you can set the LACP mode on a
group, but not on an individual port. Use the show interface status
command to check the lag status.
• The switch handles traffic in the following way when in Simple Mode:
– Tagged traffic would be dropped if the incoming port is not a member
of the incoming packet's VLAN.
– Untagged traffic is switched and untagged at the egress.
– Default VLAN tagged traffic should be switched and egress as
untagged.
– Tagged traffic that belongs to a user-created VLAN gets switched in
that VLAN and egresses as tagged.
NOTE:
The reserved VLAN ID assigned to a group is also referred to as a default
VLAN.
The following list shows the features that are available in Simple mode. Some
configuration options with the listed features might not be available.
• Management Security (No Telnet Server or Denial of Service)
• File Management
• Port Status and Statistics (Ethernet ports only)
• Port Channel Status
• Dot1x
