Configuring Stateful Firewall (ASPF)

Configuring Stateful Firewall (ASPF)


Application specific packet filter (ASPF) is status-based packet filtering. ASPF detects the application-layer sessions that attempt to pass the firewall, and discards undesired packets. ASPF can detect and filter FTP, SIP, and RTSP packets at the application layer.


  1. Run system-view

    The system view is displayed.

  2. Run firewall interzone zone-name1 zone-name2

    The interzone view is displayed.

  3. Run detect aspf { ftp | rtsp | sip }

    ASPF is configured.

    Generally, application-layer protocol packets are transmitted bidirectionally, so the direction does not need to be specified. The firewall automatically checks the packets in both directions.

    By default, ASPF is not configured in an interzone.

Verifying the Configuration

  • Run the display firewall interzone [ zone-name1 zone-name2 ] command to check ASPF information in the interzone.
