2.2 MX120e+ Introduction
The MX120e+ is part of the MX product family - in essence the MX120e+ is similar to having two MX100e+ units in one chassis.
The default configuration of the MX120e+ allows for single port operation (same as the MX100e+), dual port operation, and pass
through monitor mode. Pass through monitor mode enables bidirectional monitoring between the two 100Base-FX/1000Base-X
ports or the two 10/100/1000Base-T ports.
Dual Port Operation
When the dual port interfaces and software options are enabled, the test set can operate a combination of two ports at the
same time with the following physical port operation combinations:
Port 1 10/100/1000Base-T and Port 2 10/100/1000Base-T (copper ports only)
Port 1 100Base-FX/1000Base-X and Port 2 100BaseFX/1000Base-X (fiber ports only)
Port 1 10/100/1000Base-T and Port 1 1000Base-X (copper and fiber port combination)
Port 1 and Port 2
Port 1 (any application) and Port 2 (Loopback)
Port 1 (Loopback) and Port 2 (Loopback)
Test Applications
When operating in single port operation, any of the following test applications are available. When operating in dual port
operation, one port can run any of these test applications while the other port provides loopback.
BERT: Unframed / Framed Layer 1, and Framed Layer 2/3 Ethernet traffic generation with user selectable test
pattern for Bit Error Rate analysis.
RFC 2544: Throughput, Back-to-Back, Frame Loss and Latency conformance tests in accordance with RFC 2544
specifications.
Throughput: Ethernet traffic generation and analysis with multiple-streams to verify network throughput and jitter.
Loopback: Loop back the transmitted data while swapping the source and destination addresses of the MAC, IP and
UDP layers.

user defined test patterns to simulate various conditions. All patterns are encapsulated into an Ethernet frame to verify bit-per-bit
performance of the circuit under test. Prior to testing, the test layer, frame header, traffic profile, error injection, and control settings
of the far-end device (if applicable) must be configured.
Layer 1: Unframed mode (fiber ports only) or Framed mode
Unframed mode: Test traffic consists of a bit stream of the selected test pattern
Framed mode: Test pattern is encapsulated into a valid Ethernet frame with SOF, Preamble and CRC field

MAC, VLAN, MPLS, IP, and Test Pattern Configurations:
To configure the MAC addresses, IP addresses, VLAN tag(s), MPLS tag(s), and test pattern, tap on the frame image displayed on
the screen. This brings you to the configuration screens for all the header fields.
MAC Header Tab:
MAC Source: Use the default source address of the test set or configure a new or different address.
MAC Destination: Configure the destination MAC address of the far-end partner test set or use the ARP or ARP GW
keys to determine the MAC address of the destination IP address (ARP) or the Gateway (ARP GW). Note that a valid
IP connection needs to be up to use these functions. Refer to section 5.1 IP in the V100+ Common Functions
manual for details on IP connection.
Ethernet Type: For Layer 3 and 4 testing, the user can also configure the Ethertype:
0800-IP (Internet Protocol Version 4, IPv4)
0600-Xerox
0801-X.75 (X.75 Internet)
0805-X.25 (X.25 Level 3)

VLAN Tab: In the VLAN tab the following parameters are configured:
VLAN ID: Can be configured in the range 1 to 4094.
VLAN ID is the identification of the VLAN, which is basically used by the standard 802.1Q.
It has 12 bits which allows the identification of 4096 (2^12) VLANs.
Of the 4096 possible VIDs, a VID of 0 is used to identify priority frames and value 4095 (FFF) is reserved.
Maximum possible VLAN configurations are therefore set to 4094.
VLAN Priority: Can be configured in the range 0 to 7.
Set by the Priority Code Point (PCP), a 3-bit field which refers to the IEEE 802.1p priority.
It indicates the frame priority level from 0 (lowest) to 7 (highest), which can be used to prioritize different
classes of traffic (voice, video, data, etc.).
Type: The following selections are possible:
8100 (IEEE 802.1Q tagged frame)
88a8 (IEEE 802.1ad Provider Bridging)
Drop Eligible: If enabled, drop eligibility flag will be set.
VLAN Flooding: Enable/Disable.
VLAN Flooding Range: Specifies the number of VLAN IDs. Enter a number from 0-4096. The VLAN IDs will be
incremented by 1 until it reaches the number of times entered in the flood range.

MPLS Tab: In the MPLS tab the following parameters are configured:
MPLS label: Can be configured in the range 16 through 1,048,575 (labels 0 to 15 are reserved).
Note: Composed of 20 bits which allows for the creation of over one million labels.
CoS: Can be configured in the range 0 to 7.
Note: This field is three bits in length and maps directly to IP Precedence TOS bits to provide Class of Service
(COS).
S-bit: Can be configured 0 or 1.
Note: The S field is one bit in length and is used for stacking labels. This is important as it is used to indicate the last
label in the label stack.
TTL: Can be configured in the range 0 to 255. The default setting is 128 hops.
Note: Used to decrement the time-to-live counter.

IP Tab: In the IP tab the user must configure the destination IP address and source address. The user may also configure
the following IP header fields:
IPv4
IP Src and IP Dest: For IP Src, if the IP connection is up, refer to section 5.1 IP in the V100+ Common Functions
manual. The source address is fixed to the IP address from the IP setup menu.

IP TOS (for Quality of Service testing):
Legacy TOS (Precedence): The first three bits of the IP TOS field can be edited:
000 - Routine
001 - Priority
010 - Immediate
011 - Flash
100 - Flash Override
101 - Critical
110 - Internetwork Control
111 - Network Control
DSCP (Differentiated Services Code Point): The first six bits of the IP TOS can be edited to provide more
granular service classification.
For more information on the definition of DSCP field in IPv4 and IPv6 headers, refer to
RFC2474.
Time To Live (TTL): Can be configured in the range 0 to 255.
Fragment offset byte: Can be configured in the range 0 to 65.528.
Note: The fragment offset field, measured in units of eight-byte blocks, is 13 bits long and specifies the offset
of a particular fragment relative to the beginning of the original unfragmented IP datagram.
Protocol field: UDP (0x11), TCP (0x06), or User defined.

Data Tab: User selects a test pattern that will be encapsulated in the Ethernet frame payload (for framed mode).
Depending on the test layer, different test pattern options are available:
Layer 1 test patterns
CRPAT: Compliant Random Pattern provides broad spectral content and minimal peaking for the
measurement of jitter at component or system level.
CJTPAT: Compliant Jitter Test Pattern is a Jitter Tolerance Pattern that stresses a receiver by exposing it to
extreme phase jumps thereby stressing the Clock Data Recovery (CDR) circuitry. The pattern alternates
between repeating low transition density patterns and repeating high transition density patterns.
CSPAT: Compliant Supply Noise Pattern. Represents worst case power supply noise.
