Technology Overview 

Technology: Frame Size Details     

Home

 

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.
