Command Usage
◆ The default mapping of CoS to PHB values shown in Table 108 is based on the
recommended settings in IEEE 802.1p for mapping CoS values to output
queues.
◆ Enter a value pair for the internal per-hop behavior and drop precedence,
followed by the keyword “from” and then up to eight CoS/CFI paired values
separated by spaces.
◆ If a packet arrives with a 802.1Q header but it is not an IP packet, then the CoS/
CFI-to-PHB/Drop Precedence mapping table is used to generate priority and
drop precedence values for internal processing. Note that priority tags in the
original packet are not modified by this command.
◆ The internal DSCP consists of three bits for per-hop behavior (PHB) which
determines the queue to which a packet is sent; and two bits for drop
precedence (namely color) which is used to control traffic congestion.
