Layer 3/4 Priority Settings
– 247 –
To show the DSCP to internal PHB/drop precedence map:
1. Click Traffic, Priority, DSCP to DSCP.
2. Select Show from the Action list.
3. Select a port.

Mapping
CoS Priorities to
Internal DSCP Values
Use the Traffic > Priority > CoS to DSCP page to maps CoS/CFI values in incoming
packets to per-hop behavior and drop precedence values for priority processing.
Command Usage
◆ The default mapping of CoS to PHB values is shown in Table 17 on page 248.
◆ Enter up to eight CoS/CFI paired values, per-hop behavior and drop
precedence.
◆ 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.
Parameters
These parameters are displayed:
◆ Port – Specifies a port.
