![]() ![]() There are several functions to convert fields in the display filter language. No.Ĭurly braces are a common way to arrange mathematical expressions. The following table contains the full list of arithmetic operators: Sr. To distinguish a layer range from a slice, the hash symbol is required.Īrithmetic operators: Display Filter Arithmetic Operations: Only the inner (second) layer of the packet is matched.įor more sophisticated ranges, the same syntax as for slices applies:Į.g., tcp.port# denotes layers 2, 3, or 4 inclusive. The layer operator (#), followed by a decimal number, can be used to limit a field to a particular layer in the protocol stack: In this instance, n denotes the starting offset, while m denotes the given range’s length.
