be used in the address to indicate the appropriate number of zeros
required to fill the undefined fields.
destination-ipv6-address - An IPv6 destination 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 128 bits of the destination address.)
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: 0-128 for source prefix, 0-128 for destination prefix)
dscp – DSCP traffic class. (Range: 0-63)
next-header – Identifies the type of header immediately following the IPv6
header. (Range: 0-255)
sport – Protocol
5
source port number. (Range: 0-65535)
dport – Protocol
4
destination port number. (Range: 0-65535)
port-bitmask – Decimal number representing the port bits to match.
(Range: 0-65535)
icmp-type – The ICMP protocol number. (Range: 0-255)
time-range-name - Name of the time range. (Range: 1-32 characters)

Command Usage
All new rules are appended to the end of the list.
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, including 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)
51 : Authentication (RFC 2402)
50 : Encapsulating Security Payload (RFC 2406)
60 : Destination Options (RFC 2460)
