Execution per rule

The following Executions per rule are supported:



Drop

– when a rule matches the packet will be dropped



Redirect

– when a rule matches redirect the packet to the defined destination port



Mirror

– when a rule matches copy packet also to a defined destination port

Director Advanced Features:



Port trunking between the different Intel ports to Intel ports connected to it for load balancing between the different Intel ports



Port trunking between the different External Intel port to the external switch connected to it for load balancing between the

different external ports.



Session balancing with L3/L4 hashing or other mechanism



ISL (Inter Switch Link) Tagging per port can be added to the packets per configuration



ISL Tagging can be removed and can be forward to specific port per the ISL index.



Quality of Service support with the following features:



Priority levels: 16 internal “switch” priorities, 8 or 16 VLAN priorities (optional use of CFI bit as an extra VLAN priority bit)



Arbitrary mapping of ingress VLAN priority to an internal VLAN priority



Arbitrary mapping of an internal VLAN priority to egress VLAN priority



Arbitrary mapping of internal VLAN priority to switch priority



Arbitrary mapping of DSCP to switch priority, configurable priority source selection.



Scheduler: 8 traffic classes, arbitrary mapping of switch priorities to traffic class, deficit weighted round-robin or strict priority.



Notification: Two congestion notifications can be supported;



Virtual output queue congestion notification (VCN) and Intel proprietary backward congestion notification (FCN).



Open Flow support (consistent with OpenFlow protocol standard)



sFlow support

User defined Packet transmission with two optional modes: 1. Simple mode

– transmit on specific port. 2. Switched mode – where

switch determines destination port/ports, or with specific information such as whether or not egress processing rules should be

applied.

Storm Control Management

– Switch can support a variety storm controller. Each storm controller can be programmable to define

rat, condition (like unicast ICMP frames whose TTL is at most 1), frame type (can be OR’ed), ingress & egress port ports. Actions:

do nothing, drops frames to port (according to filter)
