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 prex length in the /x format. The range is /0
to /128. The :: notation species successive hexadecimal elds of zero.
mask Enter a network mask in /prex format (/x).
any Enter the keyword any to specify that all routes are subject to the lter.
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 species successive hexadecimal elds 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 port for the port
parameter.)
port port (OPTIONAL) 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 prex length in the /x format. The range is /0 to /
128. The :: notation species successive hexadecimal elds of zero.
count (OPTIONAL) Enter the keyword count to count packets processed by the lter.
byte (OPTIONAL) Enter the keyword byte to count bytes processed by the lter.
Defaults Not congured.

Usage Information
Most ACL rules require one entry in the CAM. However, rules with TCP and UDP port operators (gt, lt,
range) may require more than one entry. The range of ports is congured in the CAM based on bitmask
boundaries; the space required depends on exactly what ports are included in the range.
Example
An ACL rule with a TCP port range 4000 - 8000 uses eight entries in the CAM:
