Traffic provisioning
VLAN tagging - IEEE 802.1Q
The X5IP option card supports an IEEE 802.1Q compliant VLAN tagging,
classification, and filtering standard on all of its external Ethernet LAN ports or
internal WAN ports.
The Ethernet packets are processed as follows:
A customer's VLAN tagged packets are VLAN classified according to the VLAN ID
contained in the VLAN tag. The system performs VLAN ingress filtering based on the
port membership of the receiving port for a specific VLAN.
A customer's untagged and priority-tagged packets are VLAN classified according to a
default port VLAN ID that is assigned to the receiving port. The system inserts the
PVID in the VLAN tag. A unique VLAN ID can be provided to customers.
E/FE/GbE VLAN trunking
The X5IP option card aggregates E/FE/GbE traffic of multiple end-users over a single
external Ethernet or Fast Ethernet or Gigabit Ethernet port. A VLAN trunk port is a
shared member of multiple VLANs from different end-users.
GARP VLAN Registration Protocol (GVRP)
The 1643 AM/AMS supports the GARP VLAN Registration Protocol (GVRP) on the
X5IP option card. This protocol is used to maintain VLAN identification consistency
and connectivity throughout the switched WAN network.
For more information about GVRP, see
(p. 8-49).
Rapid spanning tree protocol (rSTP)
The 1643 AM/AMS supports the Rapid Spanning Tree Protocol for each virtual switch
on the X5IP option card based on the IEEE 802.1D standard.
For more information about the Rapid Spanning Tree Protocol, see
tree protocol (rSTP)" (p.
Overlength Ethernet Frames
The X5IP option card supports forwarding, encapsulation, and mapping of Ethernet
frames with lengths upto 1650 octets/bytes.
Enhanced Flow Classification
The X5IP option card supports Enhanced Flow Classification - 802.1Q mode and
801.2ad mode. Network traffic from end users can be classified into flow categories on
the edge ports of a TransLAN® domain. As a result, ports can be provisioned as
"Edge" or "Interior" ports. Edge ports are either Customer Role ports (UNI) or "Virtual
ports" on a Trunk port (E-NNI). A virtual port is the traffic over a trunk port belonging
to a single end-user and is characterized by an S-VID tag.
