Furthermore, all devices in the network must also be consistent on the maximum jumbo frame
size, so it is important to do a thorough investigation of all your devices in the communication
paths to validate their settings.
Jumbo Frame Enter the size of jumbo frame. The range is from
1522 to 10240
bytes.
Note: With different platforms, the max jumbo frame maybe different.

VLAN
A Virtual LAN (VLAN) is a group of ports that form a logical Ethernet segment on a Layer 2 Switch
which provides better administration, security, and management of multicast traffic. A VLAN is a
network topology configured according to a logical scheme rather than a physical layout. When
you use a VLAN, users can be grouped by logical function instead of physical location. All ports
that frequently communicate with each other are assigned to the same VLAN, regardless of
where they are physically on the network. VLANs let you logically segment your network into
different broadcast domains so that you can group ports with related functions into their own
separate, logical LAN segments on the same Switch. This allows broadcast packets to be
forwarded only between ports within the VLAN which can avoid broadcast packets being sent to
all the ports on a single Switch. A VLAN also increases network performance by limiting
broadcasts to a smaller and more manageable logical broadcast domain. VLANs also improve
security by limiting traffic to specific broadcast domains.
