    Overview The Packet over SONET (PoS) modules are I/O modules for the BlackDiamond 6800 series chassis-based system. These modules connect a BlackDiamond 6800 series switch to the SONET infrastructure used by metropolitan area service providers and operators of server co-location networks.

  • Page 18: Blackdiamond I/O Modules

    Overview BlackDiamond I/O Modules In addition to the PoS modules described in this guide, the BlackDiamond 6800 series switch supports a variety of I/O modules that offer a choice of port connections over different media types and distances. For more information, see the BlackDiamond 6800 Series Switch Hardware Installation Guide.

  • Page 20: Physical Description

    Overview Physical Description The PoS module consists of a printed circuit board mounted on a metal carrier that acts as the insertion vehicle in a BlackDiamond 6800 series switch (see Figure 1-1). The module carrier also includes ejector/injector handles and captive retaining screws at each end of the module front panel.

The STATUS LED indicator is located near the top end of the PoS module front panel, near the ejector/injector handle. This LED indicator is a bi-color LED (displaying in either green or amber) that signals the operating status of the module as a whole.

    Function Summary The following sections provide brief descriptions of the key functions provided by the PoS modules. Each of these sections is expanded into greater detail in Chapter 3. SONET and SDH SONET and SDH are the two terms used to identify a time division multiplexing technology that is optimized for transporting voice traffic across a digital optical network, but that is also capable of providing high-speed capacity for transporting data.
  • Page 26 PPP link using BCP. Jumbo Frames The PoS module ports provide jumbo frame support that is similar to that provided by Ethernet ports on a BlackDiamond 6800 series switch. Jumbo frames are Ethernet frames that are larger than 1522 bytes, including four bytes used for the cyclic redundancy check (CRC).

    VLAN ID (VID) mapping tables. dot1q tagmapping Each PoS port supports two VID tables: one table is used in the ingress direction; the other is used in the egress direction. Each of the tables enables an input VID to be mapped to an output VID.
  • Page 28 The PoS module also supports port tunneling. Port tunneling can be used to encapsulate and transport the raw High-Level Data Link Control (HDLC) encapsulated byte stream from one PoS port to another PoS port across an MPLS network. This allows service providers to tunnel different types of SONET HDLC streams across a non-SONET backbone like Ethernet.

    Configuring the PoS Module Configuring and Monitoring Flow Statistics Each PoS port can maintain and export traffic statistics for the flows that traverse the associated SONET link. A flow is defined as a unidirectional sequence of packets between a particular source device and destination device that share the same protocol and transport-layer information.

  • Page 110: Format Of Netflow Version 1 Export Datagram Header

    For example, each SONET port might export statistics to a dedicated flow-collector device. The ExtremeWare NetFlow implementation for the PoS module also enables a single SONET port to distribute statistics across multiple groups of flow-collector devices. This NetFlow distribution feature enables a scalable collection architecture that is able to accommodate high volumes of exported data.

  • Page 111: Collection Port And Filtering Options

    Figure 3-10: NetFlow Collection Architecture Example Collection Port and Filtering Options By default, each PoS port maintains statistics for all the flows traversing the SONET link in both the ingress and egress directions. However, generalized filtering options exist that enable a port to maintain statistics only for ingress flows, only for egress flows, or only for selected ingress and/or egress flows.

  • Page 112: Collection Architecture Scalability And Reliability

    If the flow is still active, a new flow record will be created when the next packet arrives. The PoS module transmits a NetFlow Export Datagram when 25 flow records are ready for export, or when at least one flow has been awaiting export for one second.
