But an ACL rule with TCP port lt 1023 takes only one entry in the CAM:
Rule# Data Mask From To #Covered

Commands
permit udp
c e s
Configure a filter to pass UDP packets meeting the filter criteria.
Syntax
permit udp {source address mask | any | host ipv6-address} [operator port [port]] {destination
address | any | host ipv6-address} [operator port [port]] [count [byte]] | [log] [monitor]
To remove this filter, you have two choices:
•Use the no seq sequence-number command syntax if you know the filter’s sequence number or
•Use the no permit udp {source address mask | any | host ipv6-address} {destination
address | any | host ipv6-address} command.
Parameters
permit Assign a permit filter for IPv6 packets.
permit udp Assign a permit filter for UDP packets.
source address
Enter the IPv6 address of the network or host from which the packets were sent in
the x:x:x:x::x format followed by the prefix length in the /x format.
Range: /0 to /128
The :: notation specifies successive hexadecimal fields of zero.
mask Enter a network mask in /prefix format (/x).
any Enter the keyword any to specify that all routes are subject to the filter.
host ipv6-address Enter the keyword host followed by the IPv6 address of the host in the

parameter.)
port port
(OPTIONAL) Enter the application layer port number. Enter two port numbers if
using the range logical operand.
Range: 0 to 65535
destination address
Enter the IPv6 address of the network or host to which the packets are sent in the
x:x:x:x::x format followed by the prefix length in the /x format.
Range: /0 to /128
