IEEE 802 1p mapping using the Web based management interface Note that the IEEE 802 1p to queue mapping for an interface port depends on the number of queues available at that interface This number depends on the queue set associated with the interface As displayed in Table 10 the traffic service class determines the IEEE 802 1p priority that determines the egress queue of the traffic Non IP traffic can be in the same IP service class if the non IP packets are assigned the same IEEE 802 1p priority Port types For IP traffic the Business Policy Switch ports are classified into two categories trusted and untrusted ports Usually trusted ports are connected to the core of the DiffServ network Untrusted ports are typically access links that are connected to end stations 209320 A 53 The Business Policy Switch does not trust the DSCP of IP traffic received from an untrusted port but it does trust the DSCP of IP traffic received from a trusted port Filters installed on trusted ports must not change the DSCP of the IP packets received on these ports These filters must change the IEEE 802 1p and drop precedence of the matching packets based on the incoming DSCP using a table that matches each one of the 64 DSCP values to the corresponding IEEE 802 1p priority The values can be modified by a policy server or by the user Refer to Verifying DSCP mapping on page 89 If a packet is received from a trusted port and it doe
