Information
The C-Series cannot count both packets and bytes, so when you enter the count byte options,
only bytes are incremented.
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 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 uses 8 entries in the CAM:
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 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
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.
log
(OPTIONAL) Enter the keyword log to enter ACL matches in the log.
monitor
(OPTIONAL) Enter the keyword monitor to monitor traffic on the
monitoring interface specified in the flow-based monitoring session
along with the filter operation.
