4 Product Architecture
37
The PTP 500 series provides eight traffic classes, classifying Ethernet frames into one of
eight prioritised queues based on inspection of the user priority field (802.1p) in a customer
(IEEE802.1Q) VLAN tag or provider (IEEE802.1ad) VLAN tag. Untagged frames receive a
default priority. The scheduling method is strict priority. The bridge does not implement any
VLAN functions for bridged frames apart from inspection of the priority field, and consequently
the bridge forwards tagged and untagged Ethernet frames regardless of VLAN ID and without
modification of any protocol header fields.
The management function of the PTP 500 Series Bridge is logically equivalent to a separate
protocol stack with virtual point of attachment at the Ethernet interface. This is illustrated in
Figure 10 – PTP 500 Series Bridge Layer Diagram
Each unit in the link is manageable through an IP connection. Standard IP protocols are
utilized for all management functions e.g., HP, SNMP, etc. The unit can be configured to use
VLAN tags on the management interfaces.
