Parameters top — The top parameter is mutually exclusive to the bottom parameter. When the top parameter is
specified, the top most PBits are used (if existing) to match any dot1p dot1p-value entries.
Table 18 defines the dot1p evaluation behavior when the top parameter is specified.
bottom — The bottom parameter is mutually exclusive to the top parameter. When the bottom
parameter is specified, the bottom most PBits are used (if existing) to match any dot1p dot1p-
value entries. Table 19 defines the dot1p evaluation behavior when the bottom parameter is
specified.
