Ethernet 802.2
The default setting for the Novell FDDI MAC field is Ethernet 802.2.
The Interpret 802.3 Length for Frames > 64 Bytes
This field allows the user to enable the DELHF-UA to examine the length
field of an 802.3 Ethernet frame to determine if the sending device has
added padding to a frame that contains more than the Ethernet minimum
of 64 bytes. If padding has been added, the DELHF-UA removes any
padding before sending the frame onto the FDDI ring.
The DELHF-UA automatically checks for padding all Ethernet
frames that are the minimum 64 bytes in length.
The Interpret 802.3 length for frames > 64 bytes field toggles between the
following options:
•
[DISABLED] (default setting)
•
[ENABLED]
If you retain the default setting of [DISABLED], the DELHF-UA only
examines 802.3 frames that are the Ethernet minimum 64 bytes in length.
This allows for optimal switching performance, as the DELHF-UA
assumes all frames over 64 bytes in length contain no padding.
If this field is set to [ENABLED] the DELHF-UA examines ALL 802.3
frame length fields to determine whether any of the frames contain
padding. In this setting, the DELHF-UA removes unnecessary padding
from any 802.3 frame, regardless of the size. Refer to Section 3.10.4 for
information on when to set this field to [ENABLED]. Section 3.10.5
describes how to perform this task.
