Rule Empty Rule table Extra rules used when combining QoS and hardware filtersRule Profile maskFollowing figure shows the copies of these rules Are there enough bytes for your set of filters? Okay length For example, this set of filters would work Disabled by defaultSome protocols also use filters, so use some of the length How to see the current filter resource usage on the switch Default mask Appendix a How to use the layer 4 mask in classifiersBinary 07D0 in hexadecimalPoints to remember Example 1 portsNow it is really easy to write the classifiers Example 2 portsExample 3 ports 256 128512 02465536 Following table shows the port ranges for the largest blocksC613-16058-00 REV C
