Frame Type/Size

Description

 

 

Good Frames

Frames that have no errors.

 

 

CRC Error Frames

All frames that contain CRC or Alignment errors (default is packets of

 

64 to 1518 bytes).

 

 

Fragment/Undersize

All fragments and undersized frames (default is packets less than 64

 

bytes).

 

 

Jabber/Oversize

All jabbers and oversize frames (default is packets greater than 1518

 

bytes).

 

 

Minimum Packet Size

Sets the minimum packet size for all filtering activities based on frame

(THGm only)

size. Packet sizes less than this value are considered Fragments/

 

Undersize for THGm.

 

 

Maximum Packet Size

Sets the maximum packet size for all filtering activities based on frame

(THGm only)

size. Packet sizes larger than this value are considered Jabbers/Over-

 

size for THGm.

 

 

Multi-State and Multi-Statement Filters

To create more complex filters, use Surveyor’s graphical scripting language. You’ll find it intuitive and easy to use if you have experience doing simple programming or experience working with “meta-languages.” After you become familiar with this graphical scripting language, you’ll have a powerful tool for getting exactly the data you want. It is recommended that you first have an understanding of filter templates and creating single filter statements before attempting to create advanced filters.
