An ACL rule with a TCP port range 4000 - 8000 uses eight entries in the CAM: Rule# Data Mask From To #Covered 1 0000111110100000 2 0000111111000000 3 0001000000000000 4 0001100000000000 5 0001110000000000 6 0001111000000000 7 0001111100000000 8 0001111101000000 1111111111100000 1111111111000000 1111100000000000 1111110000000000 1111111000000000 1111111100000000 1111111111000000 1111111111111111 4000 4032 4096 6144 7168 7680 7936 8000 4031 4095 6143 7167 7679 7935 7999 8000 32 64 2048 1024 512 256 64 1 Total Ports: 4001 An ACL rule with a TCP port lt 1023 takes only one entry in the CAM: Rule# Data Mask From To #Covered 1 0000000000000000 1111110000000000 0 1023 1024 Total Ports: 1024 916
