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 or destina tion-ipv6-addr ess, enter the sou rce
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 acceptable range is from 0 to 63.
•(Optional) Enter fragments to check noninitial fragme nts. This key word 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 th e 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 acceptable range is from 1 to 4294967295.
•(Optional) Enter time-range name to specify the time range that ap plies to
the deny or permit statement.
