IXIA 10 Gigabit Ethernet Load Modules

This chapter provides details about 10 Gigabit Ethernet (10GE) family of load modules the specifications and features.

The 10 Gigabit Ethernet (10GE) family of load modules implements five of the seven IEEE 8.2.3ae compliant interfaces that run at 10Gbit/second. Cards are available which offer the following interfaces:

The following figure shows an LM10GEXENPAK module.

Figure: LM10GEXENPAK

In addition, two families of multimode card are available which offers combined 10GE LAN/WAN, OC192 POS, BERT, and FEC functionality. The features available for these load modules are described in IXIA 10GE LAN/WAN and OC 192 POS Load Modules.

The full details for these families may be found at:

LSM 10GE Family

The Ixia 10 Gigabit Ethernet LAN Service Module (LSM) offers unprecedented scalability, performance, and service testing flexibility. The Ixia 10GE LSM is Ixia's third-generation 10 Gigabit Ethernet solution. It is the industry's first six-port solution, and it offers a broad portfolio of edge/ core testing solutions for the most demanding test environments including performance, scalability, and conformance testing of Layer 2-3, Routing Protocols, and high performance Layer 4-7 testing. It supports IPv4 and IPv6 wire-speed traffic generation, advanced analysis and IPv4 and IPv6 routing protocol emulation.

The Ixia 10GE LSM supports a comprehensive portfolio of service testing solutions for the next-generation service provider networks including Metro Ethernet E-LAN and E-LINE services; and MPLS VPNs such as Layer 2 VPNs, Layer 3 RFC 2547 VPNs, and VPLS.

1XM12 High Performance chassis (941-0009) is required for 80 or more ports of 10 GbE NGY XFP or SFP+ 8-port, load modules to be installed in a single chassis. A field replaceable power supply upgrade kit (943-0005) is available for the XM12 chassis (941-0002) to convert it to the high-performance version. Up to ten 8-port NGY 10GBASE-T full performance load modules are supported in an XM12 High Performance chassis, and up to eight 8-port NGY 10GBASE-T full performance load modules are supported in a standard XM12 chassis). The XM2 chassis (941-0003) supports up to twelve ports of 10GBASE-T full performance load modules.

2The LSM10GXM8XP, LSM10GXM8S, and LSM10GXM8GBT use a high performance 800MHz processor with additional layer 2 cache.

3For 10GBASE-T interfaces on NGY the ppm does change the data rate, but does not change the bit period due to phy chip limitations.

4When an NGY load module is installed in an XM12 or XM2 chassis, the maximum operating temperature of the chassis is 35°C (ambient air).

Port LEDs

The NGY 10GBASE-T load module has only 2 port LEDs:

Each 10GB port incorporates a set of LEDs, as described in the following figure.

10GE LSM Port LEDs
LED Label Usage

Link

Green if Ethernet link is up (established) or the port is in a forced Link Up state, red if link is down. Link may be down due to no signal or no PCS lock.

Tx/Pause

Green while data is transmitted. Red while flow control frames are received. Off if no traffic is passing in either direction.

Note: For NGY load modules LSM10GXM(R)8 and LSM10GXM(R)4: green indicates that Tx is active and frames being sent; red indicates Tx is paused; off indicates Tx is not active.

Rx/Error

Green while data is received. Red on any Ethernet error. Off if no frames are received.

Note: For NGY load modules LSM10GXM(R)8 and LSM10GXM(R)4: green indicates valid Rx frames are being received; red indicates error frames being received; off indicates no frames being received.

LASER ON

Green when the port's laser is turned on. Off otherwise.

Detect

Green when valid plug in module is detected, red otherwise.

Power

Green when power is on, red if power fault occurs.

Removable Carrier Cards

The 10GE10G1-01 load modules has removable carrier cards available for use:

Carrier Card Installation

To install the carrier card, do the following:

  1. Insert the card into the opening in the 10GE LSM module.
  2. Slide the card along the guide rails until it connects to the load module.
  3. Tighten the screws so that the carrier card is firmly in place. Do not over tighten the screws (no more than a quarter turn once flush with the card front).

The carrier card can be installed either before or after the load module is connected to the chassis. It is best not to attach the transceiver to the carrier card until the card is installed in the load module. Load modules should be screwed down in the chassis before removing or installing a carrier card, to prevent from accidentally dislodging a load module from the chassis backplane.

Note: The carrier cards do not come with the required transceivers. They must be purchased separately.

XENPAK/XAUI Connectors

The LSM10G1-01 load module has XAUI and XENPAK connectors available. See XAUI Connectors and XENPAK Connectors above for more information on XENPAK connectors.

These connectors are only applicable when the XENPAK carrier is being used.

Statistics

Statistics for 10GE LSM cards (except NGY), under various modes of operation may be found in Statistics for 10GE LSM Modules (except NGY). Statistics for NGY load modules may be found in Statistics for NGY Modules.

NGY Fault Handling

IEEE Requirements

IEEE 802.3ae, section 46.3.4 defines how a Reconciliation Sublayer (RS) shall respond to Local and Remote Faults. Response to a Local Fault is to immediately cease sending traffic on the transmit data path (even if doing so truncates a frame) and to send continual Remote Faults. Response to a Remote Fault is to stop sending MAC data (completing any frame that is being transmitted) and to send continual idles.

NGY Operation

NGY load modules have a single statistic for Faults called Link Fault State. This statistic is real-time and indicates the current state of the port's Reconciliation Sublayer (RS) state machine. The possible statistics values are:

Features that force deviation from IEEE spec

Note: In general, if a NGY port appears to be transmitting according to the Frames Sent statistic, be aware that Link Fault State may override this.

Tx Ignores Rx Link Faults

This feature is enabled through the Link Fault Signaling tab of Port Properties. When the feature is enabled, the Fault statistic continues to indicate the RS state of the port; however, the transmit-side response behaves as if no fault was received. That is to say, Remote Faults are not sent as a response to Local Fault and Idles are not forced as a response to Remote Fault, even though Link Fault State indicates the board is in a Fault state.

Transmit Ignores Link Status

This feature is enabled through the Transmit Modes tab of Port Properties. When the feature is enabled, a port is permitted to transmit under conditions that would normally inhibit transmit. For instance, a port that has no link and is not in diagnostic loopback appears in IxExplorer as red color, and is normally not permitted to transmit. Enabling this feature allows transmit. When the feature is enabled, the statistic called Link State indicates `Ignore Link'.

Note that if the port is in Fault, enabling this feature and forcing transmit may result in misleading results. The port shown in the following stat view (See the following figure) is ignoring link (see Link State statistic), is in Remote Fault (see Link Fault State statistic), yet appears to be transmitting (see Frames Sent Rate statistic). The reality is that no frames are actually leaving the port because the port is in Remote Fault. This is because the block that maintains the transmit statistics is located before the block that forces idles as a response to Remote Fault.

Figure: Statistic View for NGY, Ignore Link Status

Intrinsic Latency Adjustment

This option, when present and enabled, reduces the measured latency by the amount of latency that is induced by the test equipment itself (not the DUT). For a specific transceiver, the system retrieves its pre-determined latency value and subtracts this from the measured overall latency. For an `unknown' transceiver (not previously measured), it calculates and stores the intrinsic latency value.

On the General tab in Port Properties, the Latency Calibration option is only enabled for cards with transceivers that have not been pre-measured for intrinisic latency by Ixia. The Latency Calibration option is grayed-out if any one of the following conditions are present:

The Latency Calibration option is enabled if the transceiver is XENPAK or X2 but no pre-calibrated value is found in the stored list. The Latency Calibration option is also enabled for transceivers that you have previously calibrated, so that the calibration measurement may be repeated (if desired).

Selecting the Latency Calibration option runs a Tcl script that measures intrinsic latency and stores the value in an .xml file. The .xml file contains the values that you have produced and saved. Each value is identified for a specific transceiver (per manufacturer, model, and serial number). You can run the calibrate process repeatedly with the same transceiver (if desired). Each new measurement overwrites the previous one for that transceiver.

Running the calibration measurement puts the port into a special loopback mode to measure intrinsic latency. When done, the port is put back into default normal mode. Any port configuration you have set before calibrating intrinsic latency, is lost as the port reverts to a default configuration.

The Enable check box is grayed out when no value exists in the system for the specific transceiver. If a value exists (in the .xml file) then the Enable check box is available. Select the check box to enable the intrinsic latency adjustment.

After the intrinsic latency adjustment has been done, you may want to refresh the chassis or close and reopen the Port Properties dialog.

Note: The LSM10GMS-01 load module always compensates for intrinsic latency it is not optional. Also, this load module does not support the'No CRC' option. Any imported stream with No CRC enabled is Forced Valid to `Bad CRC'.

The load module contains a phase-locked loop (PLL) that reduces the jitter of the input clock, either from the internal or external clock source. The bandwidth of the PLL is approximately 1kHz.

XAUI Connectors

The following connectors and adapters are available for the XAUI Load Modules and are discussed in Appendix A, XAUI Connector Specifications.

MDIO

A Management Data Input/Output (MDIO) interface is provided to you. The Ixia Load Module acts as the Station Management entity (STA), and can control one or more MDIO Manageable Devices (MMD) in the users system. Multiple MMDs can be attached to the interface. You can set/read the MDIO control/status registers inside a MMD through a graphical user interface.

The connector used for the MDIO interface is a 15-pin female D-sub and provides with the ability to add up to two external Mii interfaces compliant to either 802.3 clause 22 or 802.3ae clause 45. The connector pin assignments, Mii Interface, signal names, and functional descriptions are listed in the following table.

Figure: MDC/MDIO D-sub Connector Pin Assignments

Note: The MDIO on the Ixia XAUI Load Module is 3.3V while the Ixia XENPAK Load Module, when used with the adapter for XAUI, is 1.2V. The reason for the difference is that the XENPAK MSA requires 1.2V for MDIO whereas most XAUI SerDes chips require 3.3V (LVTTL). Therefore, when using the XAUI Load Module to test a XENPAK transceiver or SerDes, which require 1.2V, a level shifter is needed to convert 3.3V to 1.2V.

The MDIO/MDC interface has a clock line (MDC) and bi-directional data line (MDIO) as defined in IEEE 802.3ae. In addition to these, a +5Vdc supply, and data direction control line (DIR) are provided to make interfacing easier for you. The +5Vdc output is intended to power buffers and/or optocouplers at the user-end of the cable. This supply can be turned ON or OFF under software control through the GUI.

The +5Vdc supply is OFF when the chassis is initially powered-up, or following a reset.

Power Sequencing Specification

The Xenpak 2.1 MSA does not specify any particular power sequencing for the various Xenpak power supply rails (3.3V, 5V, and APS).

When Xenpak Power is enabled, power sequencing is as follows:

Reset

Hardware asserts a Reset by bringing Xenpak connector pin 10 low whenever either of the following conditions is true:

The hardware continues to assert Reset until both of these items are false. Once Xenpak Power is asserted, or if a Xenpak is hot-plugged, the system waits 5 seconds for Xenpak initialization (per MSA 2.1). Reset is then de-asserted, and the system waits an additional 500 ms for any vendor-based reset management to complete initialization. After this final 500 ms delay, the load module assumes the Xenpak module is ready for MII access or to transmit and receive.
