udf-delete

A User Defined Field (UDF) can match up to 128 bytes of a packet starting from the first byte of the packet. The relative offset can be given to the match location. The length of the match can be from 1 to 4 bytes. Hardware with a Trident chip supports the creation of 8 UDF IDs. Each ID can match a 2 byte portion of a packet. Creating a UDF with a length of 3 or 4 bytes requires 2 UDF IDs whereas a UDF

with length of 1 or 2 bytes required 1 UDF id. The length specified for each UDF determines the total number of UDFs supported by Netvisor. If you specify a length of 3 or 4 bytes, a maximum of 4 UDFs can be created. If you specify a length of 1 or 2 bytes, a maximum of 8 UDFs can be created.
