Traffic provisioning
Q-tagging mode
The X5IP option card supports Flow Classification in the IEEE 802.1Q tagging mode.
Users can assign a similar flow profile as described above for the IEEE 802.1ad
tagging mode. Note that the QoS classification operations will only modify the
end-user priority (UP) bits.
CQS - Provider Bridge Mode (PBM) and Q-tagging mode
The X5IP option card supports classification, queuing, and scheduling functions for
four traffic classes, associated with three queues in the Provider Bridge Mode and
Q-tagging mode.
Note: In the Q-tagging mode, this function is a non-standard conformance operation
mode in which the customer's user priority (UP) bits will be modified.
Ingress rate control in Provider Bridge Mode (PBM) and Q-tagging mode
The X5IP option card supports ingress rate control values through rate policing per
flow at customer role ports in provider bridge mode and Q-tagging mode. This
function is based on 'Strict policing' values where (PIR=CIR) and 'Oversubscription'
values where (PIR>CIR).
Note: In the Q-tagging mode, this function is a non-standard conformance operation
mode in which the third user priority (UP) bit of the customer tag will be modified.
LAN port provisioning
The following sections describe LAN port provisioning capabilities that are supported
by the X5IP option card.
LAN port as network port or customer port
The X5IP option card can be used to operate a LAN port as a network port or
customer port. Based on the IEEE 802.1Q and IEEE 802.1ad modes, the 1643
AM/AMS supports a flexible operational port role assignment per LAN port. During
port provisioning, a LAN port can be set to a 'network' role.
The following properties are applicable to a port in a 'network' port role:
• No V-LAN tagging operations
• Provider based Spanning Tree Protocol (provisionable, default=enabled)
• GVRP operations (provisionable, default=enabled)
The following properties are applicable to a port in a 'customer' port role:
• V-LAN tagging operations
• No provider based Spanning Tree Protocol
• No GVRP operations
WAN port as network port or customer port
In IEEE 802.1Q and IEEE 802.1ad modes, the Network Element supports a flexible
operational port role assignment per WAN port. Next to the default "network" port
role, a WAN port can be set to "customer" role.
