any – Any IP address (an abbreviation for the IPv6 prefix ::/0).
host – Keyword followed by a specific source IP address.
source-ipv6-address - An IPv6 source 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.
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 64 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, 0-8 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)
time-range-name - Name of the time range.
(Range: 1-16 characters)
