Abstract
A firewall processing card from a plurality of firewall processing cards coupled to a chassis, is selected by a load balancing engine (or other mechanism) and receives the data packet over the fabric channel. First, if the session match exists to management-type data packets the data packet is returned to the I/O board and if a match exists to user data packets the data packet is sent to a firewall service of the firewall processing card. If no session match exists, the firewall processing card checks for a policy match to the data packet for creating a new session or drops the data packet. The I/O board receives the data packet returned from the processing blade over the base channel and checks for a session matching to the data packet. If a session match exists and the data packet is a management data packet, the data packet is sent to a management service at a user level of the I/O board and if not a management data packet the data packet is dropped. If no session match exists, the I/O board creates a new session or drops the data packet.
