However, rules with TCP and UDP port operators (gt, lt, range) may require more than one entry. The range of ports is configured in the CAM based on bitmask boundaries; the space required depends on exactly what ports are included in the range. For example, an ACL rule with TCP port range 4000 - 8000 will use 8 entries in the CAM: Rule# Data Mask From To #Covered 1 0000111110100000 1111111111100000 4000 4031 32 2 0000111111000000 1111111111000000 4032 4095 64 3 0001000000000000 1111100000000000 4096 6143 2048 4 0001100000000000 1111110000000000 6144 7167 1024 5 0001110000000000 1111111000000000 7168 7679 512 6 0001111000000000 1111111100000000 7680 7935 256 7 0001111100000000 1111111111000000 7936 7999 64 8 0001111101000000 1111111111111111 8000 8000 1 Total Ports: 4001 But an ACL rule with TCP port lt 1023 takes only one entry in the CAM: Related Commands Rule# Data Mask From To #Covered 1 0000000000000000 1111110000000000 0 1023 1024 Total Ports: 1024 deny deny tcp Assign a deny filter for IP traffic. Assign a deny filter for TCP traffic. ipv6 access-group s S6000 Assign an IPv6 access-group to an interface. Syntax ipv6 access-group access-list-name {in | out} [implicit-permit] [vlan range] To delete an IPv6 access-group configuration, use the no ipv6 access-group access-list-name {in} [implicit-permit] [vlan range] command. Parameters access-list-name in | out implicit-permit vlan range Enter the name of a configured access list, up to 140 characters. Enter either the keyword in or out to apply the IPv6 ACL to incoming traffic (ingress) or outgoing traffic (egress). (OPTIONAL) Enter the keyword implicit-permit to change the default action of the IPv6 ACL from implicit-deny to implicit-permit (that is, if the traffic does not match the filters in the IPv6 ACL, the traffic is permitted instead of dropped). (OPTIONAL) Enter the keyword vlan followed by the VLAN range in a comma separated format. Range: 1 to 4094 Defaults Disabled Command Modes INTERFACE 162 | Access Control Lists (ACL)
