any – Any IP address (an abbreviation for the IPv6 prefix ::/0).
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)
