IXIA LSM1000XMVR8-01 LAN Services Modules

Ixia's Gigabit Ethernet XMVR LAN Services Modules （LSMs） offer Layer 2-3 network testing functionality in a single test system. Each test port supports wire-speed Layer 2-3 traffic generation and analysis and medium performance routing/bridging protocol emulation. With industry-leading16 Dual-PHY ports per module, ultra-high density test environments can be created for auto-negotiable 10/100/1000 Mbps Ethernet over copper as well as Gigabit/100FX Ethernet over fiber. With 12 slots per XM12 High Performance chassis, up to 192 Gigabit Ethernet test ports are supported in a single test system
Each port on a GE XMVR module contains a RISC processor running Linux and a full testing-optimized TCP/IP stack. This architecture provides the performance and flexibility required for testing routers, switches, broadband and wireless access devices, and many other networking devices.
Ixia's Gigabit Ethernet XMVR LAN Services Modules （LSMs） are offered in 4, 8, 12 and 16 port configurations, providing scalability and affordability for many testing requirements.

Specifications

Flexible Packet Generation

Each Ixia GE XMVR test port is capable of generating precisely controlled network traffic at up to wire speed of the network interface using Ixia’s IxExplorer test application. Up to millions of packet flows can be configured on each port with fully customizable packet header fields. Flexible header control is available for Ethernet, IPv4/v6, IPX, ARP, TCP, UDP, VLANs, QinQ, MPLS, GRE, and many others. Payload contents can also be customized with incrementing/decrementing, fixed, random, or user-defined information. Frame sizes can be fixed, varied according to a pattern, or randomly assigned across a weighted range. Rate control can be flexibly defined in frames per second, bits per second, percentage of line rate, or inter-packet gap time.
 

Real-Time Latency

Packets representing different traffic profiles can be associated with Packet Group Identifiers （PGIDs）. The receiving port measures the minimum, maximum, and average latency in real time for each packet belonging to different groups. Measurable latencies include:

• Instantaneous latency and inter-arrival time where each packet is associated with one group ID
• Latency bins, where PGIDs can be associated with a latency range
• Latency over time, where multiple PGIDs can be placed in "time buckets" with fixed durations
• First and last time stamps, where each PGID can store the timestamps of first and last received packets

Transmit Scheduler

Two modes of transmission are available - Packet Stream and Advanced Stream Scheduler: 

Packet Stream Scheduler In Packet Stream Scheduler mode, the transmit engine allows configuration of up to 256 unique sequential stream groupings on each port. Multiple streams can be defined in sequence, each containing multiple packet flows defined by unique characteristics. After transmission of all packets in the first stream, control is passed to the next defined stream in the sequence. After reaching the last stream in the sequence, transmission may either cease, or control may be passed on to any other stream in the sequence. Therefore, multiple streams are cycled through, representing different traffic profiles to simulate real network traffic.
Advanced Stream Scheduler In Advanced Stream Scheduler mode, the transmission of stream groupings is interleaved per port. For example, assume a port is configured with three streams. If Stream 1 is defined with IP packets at 20% of line rate, Stream 2 is defined with TCP packets at 50% of line rate, and Stream 3 is defined with MPLS packets at 30% of line rate, data on the port will be transmitted at an aggregate utilization of * with interleaved IP, TCP, and MPLS packets.

Extensive Statistics

• Real-time 64-bit frame counts and rates
• Spreadsheet presentation format for convenient manipulation of statistics counters
• Eight Quality of Service counters （supporting 802.1p, DSCP, and IPv4 TOS measurements）
• Six user-defined statistics that use a trigger condition
• Extended statistics for ARP, ICMP, and DHCP
• Transmit stream statistics for frame counts and rate
• External logging to file for statistics and alerts
• Audible and visual alerts with user-definable thresholds

Data Capture

Each port is equipped with 8 MB of capture memory, capable of storing tens of thousands of packets in real time. The capture buffer can be configured to store packets based on user-defined trigger and filter conditions. Decodes for IPv4, IPv6, UDP, ARP, BGP-4, IS-IS, OSPF, TCP, DHCP, IPX, RIP, IGMP, CISCO ISL, VLAN, and MPLS are provided. 
 

Data Integrity

As packets traverse through networks, IP header contents may change resulting in the recalculation of packet CRC values. To validate device performance, the data integrity function of Gigabit Ethernet XMVR modules allows packet payload contents to be verified with a unique CRC that is independent of the packet CRC. This ensures that the payload is not disturbed as the device changes header fields. 
 

Sequence and Duplicate Packet Checking

Sequence numbers can be inserted at a user-defined offset in the payload of each transmitted packet. Upon receipt of the packets by the Device under Test （DUT）, out-of sequence errors or duplicated packets are reported in real time at wire-speed rates. The user can define a sequence error threshold to distinguish between small versus big errors, and the receive port can measure the amount of small, big, reversed, and total errors. Alternatively, the user can use the duplicate packet detection mode to observe that multiple packets with the same sequence number are received and analyzed. 
 

Routing/Bridging Protocol Emulation

Ixia's Gigabit Ethernet XMVR modules support performance and functionality testing using routing/bridging protocol emulation via the IxNetwork and IxAutomate applications. Protocols supported include IPv4/IPv6 routing （BGP-4, OSPF, IS-IS, and RIP）, MPLS （RSVP-TE, LDP, L2 MPLS VPNs, L3 MPLS VPNs, and VPLS）, multicast （IGMP, MLD, and PIM-SM）, and bridging （STP, RSTP, MSTP）. Medium scalable scenarios can be created emulating up to 100 routers advertising thousands of routes per test port. Up to wire-speed Layer 2/3 traffic can be automatically created to target routes and MPLS tunnels. 
 

Tcl API

Ixia's Gigabit Ethernet XMVR modules are supported by a comprehensive Tcl Application Programming Interface （API）. This API allows users to develop custom scripts, and integrate the modules into automated test environments.
