number of zeros required to fill the undefined fields.
dscp – DSCP traffic class. (Range: 0-63)
sport – Protocol
5

(Range: 0-65535)
time-range-name - Name of the time range. (Range: 1-32 characters)
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

Command Usage
All new rules are appended to the end of the list.
Source and destination port parameters are only available when protocol
parameters are specified in the rule.
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)
5. Includes TCP and UDP.
