New inline filters are added in QM5452 or older version

Users can utilize Inline Search to effectively filter packets according to source or destination IPv4 and IPv6 addresses, as well as source or destination port numbers and protocols. Below, you'll find reference examples of potential entries to guide you in this process.

Inline Filter File

The following content explains step by step guide for using an inline search filter file in the packet search.

Upload Filter File

  1. On your local system, open TextEditor, enter filter syntax in BPF format and save it as .txt

    • example: ((tcp[8:4]\&0xffffffff == 0) and (tcp[tcpflags] \& tcp-syn != 0))

  2. Upload the file to the packet search

  3. Click the search button

Filter File Search

Uploaded filter files are stored in the system. You can go to ‘FilterFile’ and select the file for your search. You can also delete the file from this section.

File Entry shows the contents of the file you selected. To use the filter, click the ‘Confirm Selection’ button.

Filter Strings
