C ONFIGURING AN
E XTENDED IP V 6 ACL
Use the Security > ACL (Configure ACL - Add Rule - IPv6 Extended) page
to configure an Extended IPv6 ACL.
CLI R EFERENCES
◆ "permit, deny (Extended IPv6 ACL)" on page 982
◆ "show ipv6 access-list" on page 984
◆ "Time Range" on page 817
P ARAMETERS
These parameters are displayed:
◆ Type – Selects the type of ACLs to show in the Name list.
◆ Name – Shows the names of ACLs matching the selected type.
◆ Action – An ACL can contain any combination of permit or deny rules.
◆ Destination Address Type – Specifies the destination IP address. Use
“Any” to include all possible addresses, or “IPv6-prefix” to specify a
range of addresses. (Options: Any, IPv6-prefix; Default: Any)
◆ Destination IPv6 Address – An IPv6 address or network class. The
address must be formatted according to RFC 2373 “IPv6 Addressing
Architecture,” using 8 colon-separated 16-bit hexadecimal values. One
double colon may be used in the address to indicate the appropriate
number of zeros required to fill the undefined fields. (The switch only
checks the first 64 bits of the destination address.)
◆ Destination Prefix-Length – A decimal value indicating how many
contiguous bits (from the left) of the address comprise the prefix; i.e.,
the network portion of the address. (Range: 0-64 bits)
◆ DSCP – DSCP traffic class. (Range: 0-63)
◆ Next Header – Identifies the type of header immediately following the
IPv6 header. (Range: 0-255)
Optional internet-layer information is encoded in separate headers that
may be placed between the IPv6 header and the upper-layer header in
a packet. There are a small number of such extension headers, each
identified by a distinct Next Header value. IPv6 supports the values
defined for the IPv4 Protocol field in RFC 1700, and includes these
commonly used headers:
0 : Hop-by-Hop Options (RFC 2460)
6 : TCP Upper-layer Header (RFC 1700)
17 : UDP Upper-layer Header (RFC 1700)
43 : Routing (RFC 2460)
44 : Fragment (RFC 2460)
50 : Encapsulating Security Payload (RFC 2406)
51 : Authentication (RFC 2402)
60 : Destination Options (RFC 2460)
