An ACL rule with TCP port lt 1023 takes only one entry in the CAM:
Rule# Data Mask From To #Covered
1 0000000000000000 1111110000000000 0 1023 1024

Commands
deny – assigns a filter to deny IP traffic.
deny udp – assigns a filter to deny UDP traffic.
deny udp
Configure a filter to drop user datagram protocol (UDP) packets meeting the filter criteria.
Syntax
deny 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
• Use the no deny udp {source address mask | any | host ipv6-address}
{destination address | any | host ipv6-address} command
Parameters
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. The range is /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 x:x:x:x::x format.
The :: notation specifies successive hexadecimal fields of zero.
operator (OPTIONAL) Enter one of the following logical operand:
• eq = equal to
• neq = not equal to
• gt = greater than
• lt = less than
• range = inclusive range of ports (you must specify two ports for the port command
parameter).
port port
Enter the application layer port number. Enter two port numbers if using the range logical
operand. The range is 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. The range is /0 to /128.
The :: notation specifies successive hexadecimal fields of zero.
count (OPTIONAL) Enter the keyword count to count packets processed by the filter.
byte (OPTIONAL) Enter the keyword byte to count bytes processed by the filter.
Defaults Not configured.
