1. Filter by specifying a range of message lengths.

frame.len >= <最小长度> and frame.len <= <最大长度>

For example, to filter out messages with a length between 100 and 200 bytes, you can use the following filtering expression:

frame.len >= 100 and frame.len <= 200

1. Filter by specifying a specific message length.

frame.len == <特定长度>
