Technology Overview
Technology: Frame Size Details
64 or 1518 bytes are used most often since these represent the normal minimum
and maximum frame size allowed by the network.
The standard frame sizes for Ethernet testing are 64, 128, 256, 512, 1024, 1280,
and 1518 bytes.
When testing RFC2544 with VLAN and/or MPLS tags, 64 bytes is no longer a proper
frame length.
With systems that support jumbo frames, such as 4096- or 9000- byte frames, these
frame sizes should be tested as well.
The XTT 5000 defaults to the frame size defined in RFC 2544, but allows you to set
the frame size to any valid value.
