Enter
deny
or
permit
to specify whether to deny or permit the packet if
conditions are matched. These are the conditions:
•
For
protocol
, enter the name or number of an Internet protocol:
ahp
,
esp
,
icmp
,
ipv6
,
pcp
,
stcp
,
tcp
, or
udp
, or an integer in the range 0 to 255
representing an IPv6 protocol number.
Note
For additional specific parameters for ICMP, TCP, and UDP, see
Steps 3b through 3d.
•
The
source-ipv6-prefix
/
prefix-length
or
destination-ipv6-prefix
/
prefix-length
is the source or destination IPv6 network or class of networks
for which to set deny or permit conditions, specified in hexadecimal and
using 16-bit values between colons (see RFC 2373).
•
Enter
any
as an abbreviation for the IPv6 prefix ::/0.
•
For
host
source-ipv6-address
o
r destination-ipv6-address,
enter the source
or destination IPv6 host address for which to set deny or permit conditions,
specified in hexadecimal using 16-bit values between colons.
•
(Optional) For
operator
, specify an operand that compares the source or
destination ports of the specified protocol. Operands are
lt
(less than),
gt
(greater than),
eq
(equal),
neq
(not equal), and
range
.
If the operator follows the
source-ipv6-prefix
/
prefix-length
argument, it
must match the source port. If the operator follows the
destination-ipv6-
prefix
/
prefix-length
argument, it must match the destination port.
•
(Optional) The
port-number
is a decimal number from 0 to 65535 or the
name of a TCP or UDP port. You can use TCP port names only when
filtering TCP. You can use UDP port names only when filtering UDP.
•
(Optional) Enter
dscp
value
to match a differentiated services code point
value against the traffic class value in the Traffic Class field of each IPv6
packet header. The range is from 0 to 63.
•
(Optional) Enter
fragments
to check noninitial fragments. This keyword is
visible only if the protocol is
ipv6
.
•
(Optional) Enter
log
to cause an logging message to be sent to the console
about the packet that matches the entry. Enter
log-input
to include the
input interface in the log entry. Logging is supported only for router ACLs.
•
(Optional) Enter
routing
to specify that IPv6 packets be routed.
•
(Optional) Enter
sequence
value
to specify the sequence number for the
access list statement. The range is from 1 to 4294967295.
•
(Optional) Enter
time-range
name
to specify the time range that applies to
the deny or permit statement.
