Large Send Offload; Locally Administered Address - StarTech.com ST2000SPEXI Instruction Manual

Restrictions:
• Jumbo Frames can be implemented simultaneously with VLANs and teaming,
however Jumbo frames are not supported in multi-vendor team configurations.
• Supported protocols are limited to IP (TCP, UDP).
• Jumbo frames require compatible switch connections that forward Jumbo Frames.
To configure Jumbo Frames at the switch, consult your network administrator or
switch user's guide.
• When standard sized Ethernet frames (64 to 1518 bytes) are used, there is no benefit
to configuring Jumbo Frames.
• The Jumbo Frames setting on the switch must be set to at least 8 bytes larger than
the adapter setting for Microsoft Windows operating systems, and at least 22 bytes
larger for all other operating systems.

Large Send Offload

Enables the adapter to offload the task of segmenting TCP messages into valid
Ethernet frames.
Because the adapter hardware can complete data segmentation much faster than
operating system software, this feature can improve transmission performance. The
adapter also uses fewer CPU resources.
Large Send Offload can be configured separately for IPv4 and IPv6.

Locally Administered Address

The Locally Administered Address feature allows you to override a device's MAC
Address and assign an address of your choice. The address is a 12-digit hexadecimal
number in the range: 0000 0000 0001 – FEFF FFFF FFFF.
CAUTION: Make sure no other systems on the network use this address.
NOTES:
• Do not use a multicast address (least significant bit of the high byte = 1).
For example, in the address 0y123456789A, "y" cannot be an odd number. (y must
be 0, 2, 4, 6, 8, A, C, or E.)
• To restore the default MAC address, click Use Default.
• You cannot change the address if the adapter is part of a team.
• Changing this setting may cause a momentary loss of connectivity.
