V7.x Packet Controllers
PCX/PCX-2 Controller Overview
Xedge Switch Version 7.2 and later supports the Xedge PCX-2 slot controller. Both
the PCX-2 and the earlier PCX device have two daughter cards: an LPM card and
a network processor. In this section, the information applies to both the PCX-2 and
PCX controllers, except where noted.
Features & Benefits
•
Complies with Metro Ethernet Forum (MEF) compliant Ethernet Private Line
•
Conforms with IEEE 1588 Precision Time Protocol (Version 2) as
an IEEE 1588 Client over Ethernet.
•
High speed, high capacity packet switching
•
Dual control plane for MPLS or ATM transport
•
Supports layer 2 or layer 3 VPNs
•
Flexible Routing includes PNNI, OSPF-TE
•
Reduces OPEX and CAPEX
Traffic Management
PCx offers superior traffic management capabilities to assure that priority traffic
(for example, real-time IP flows such as IP video packets) is not perturbed when the
destination route encounters congestion from bursty traffic. Each PCx module acts
on priorities based on destination IP addresses, and assures QoS across the wide-
area network. Through intelligent tunnel management and queueing, PCx buffers
up to 1000 frames to handle burst traffic.
Routing
PCx determines routes based on IP destination addresses. Layer-3 tunnels are built
across the Xedge cloud to other PCx devices and selected Layer-3 devices (e.g.,
centralized router resources or external routers connected to the network via MPLS or
ATM interfaces). Each PCx supports more than 256 IP tunnels which may be
established using OSPF, RIP2, deterministic MPLS/ATM routes, or by selecting a
specific PCx tunnel as a local site's default gateway. PCx can be configured with auto
re-routing with variations on limited and restricted re-routing.
Ethernet Connections
The Ethernet interface is provided by connectors on the PCX-2 base card.
For the PCX, the Ethernet connectors are located on the GENPC daughter card.
•
Gigabit Ethernet connectivity is provided by two GbE ports which require small
format pluggable (SFP) inserts.
•
Fast Ethernet connectivity is provided by eight 10/100 Mbps FE ports.
•
FE Activity and GbE Activity LEDs are described in
Power Up or Reboot Sequence
