  • Page 31: Access Control

    5.3 User Interface Advanced Mode The NetTESTER offer a simplified version of the user interface found on the Metrodata EDD family products. Parts of the EDD functionality that are not normally relevant to the tester application have been removed. Should they be needed, however, these hidden functions can still be accessed by switching the user interface to 'Advanced Mode'.
  • Page 32 METRODATA NetTESTER FAMILY USER MANUAL Reference should be made to the EDD family user manual [1] for more guidance on using the advanced mode. It is recommended that the mode is accessed in order to make simple changes to default settings that are not accessible from the normal tester user interface.
  • Page 33 METRODATA NetTESTER FAMILY USER MANUAL 6 VLANS AND TAGGING IEEE 802.1Q [2] defines the concept of a Virtual LAN (VLAN), a mechanism for partitioning traffic that is carried over a physical LAN so that it appears as a number of separate LAN connections. This is done by adding an extra 4-byte 'tag' near the start of each packet, which identifies the VLAN to which it belongs using a number in the range 1-4095 (the VLAN ID).

  • Page 34: Management Interfaces

    METRODATA NetTESTER FAMILY USER MANUAL 7 LAYER 3/4 OPERATION: TCP/IP AND UNIT MANAGEMENT The unit is primarily a Layer 2 (VLAN and Ethernet) device, but Layer 3/4 (TCP/IP) functionality is includes in order to provide the following: • Access to the unit's user interface via a network (as opposed to a terminal) connection.
  • Page 35 METRODATA NetTESTER FAMILY USER MANUAL Since a Windows PC will typically fall back to using an Automatic Private IP address if it fails to find a DHCP server, randomly selecting an address in the 169.254.x.x range, the unit should become accessible without having to change any settings on the PC.

  • Page 36: Telnet And Ssh

    METRODATA NetTESTER FAMILY USER MANUAL Note: Modern web browsers tend to open several TCP connections at once for a single session, so the connection limit is likely to be reached sooner than expected when using HTTP access. 7.5 Telnet and SSH Telnet [3] and SSHv2 [4] are both protocols offering terminal-like access to the unit over a network connection.
  • Page 37 METRODATA NetTESTER FAMILY USER MANUAL SNMP runs over UDP/IP. The messages support a small number of primitive operations (read, write, etc.) Unsolicited messages from the agent, known as notifications or traps, are also supported. Various versions of the protocol exist. The unit support versions 1 and 2c.
  • Page 38 METRODATA NetTESTER FAMILY USER MANUAL tftp -i 192.168.0.11 put demo.cfg settings/demo.cfg To transfer a file from the unit, the command line would be: tftp –i <unit ip address> get <unit filename> <pc filename> As an example, the following command would read a configuration file named demo.cfg from the unit and save this on the PC.

  • Page 39: File System

    METRODATA NetTESTER FAMILY USER MANUAL 8 FILE SYSTEM 8.1 File Types Files can be of 3 different types: Software File This type of file contains software to be programmed into the unit. Configuration File This type of file contains the information necessary to define all the configuration settings of a unit (see section 3.2.3).
  • Page 40 METRODATA NetTESTER FAMILY USER MANUAL Figure 8.1 File system, as seen by SFTP client Files contained in each of the folders may be read and (except for the report files) written, over-written, renamed or deleted by an external client (though only SFTP supports renaming and deleting).
  • Page 41 METRODATA NetTESTER FAMILY USER MANUAL 9 SERVICE LEVEL AGREEMENTS (SLAS) The unit uses the concept of a Service Level Agreement (SLA) as proposed by MEF [6] This defines the service supplied to the customer by the provider in terms of a list of measurable parameters with minimum acceptable values for each.
  • Page 42 METRODATA NetTESTER FAMILY USER MANUAL 3. Utilisation. As above, but both the preamble and inter-packet gap (IPG, 12 bytes) are included. Include Tags Where packets are tagged, the tag bytes may be included or excluded for IR purposes. Separate controls are available for c-tags, s- tags and tags that are to be added by external equipment.
  • Page 43 METRODATA NetTESTER FAMILY USER MANUAL FTD/IFDV In order to comply with the SLA, FTD and Percentile IFDV parameters must be satisfied by a portion of packets specified by this percentile value. Maximum Performance parameters apply only to Transmission Unit packets up to the size specified. Larger packets may be passed at the provider's discretion, with no performance assurances.

  • Page 44: Loopback Function

    METRODATA NetTESTER FAMILY USER MANUAL 10 SERVICE ACTIVATION TESTING Service Activation Testing is the term used to describe testing of a service prior to it carrying any live traffic. Simulated traffic is generated and used to measure aspects of the service performance. This can then be compared to the Service Level Agreement (SLA), to provide confidence that this will be met in the live environment, or to give advance warning of potential problems.
  • Page 45 METRODATA NetTESTER FAMILY USER MANUAL 00:C0:81:4x.xx.xx* Any User * - x.xx.xx is the remainder of the unit MAC address, i.e. this is the unit MAC address modified by setting either bit 23 or 22. ** - These are referred to in places as "Magic MAC" addresses.
  • Page 46 Further, packets carrying a UDP payload will have their UDP source/destination ports swapped and the UDP checksum set to zero. The Layer 4 mode is intended for use where the traffic comes from a Metrodata device operating in 'Layer 3' tester mode (see below).
  • Page 47 METRODATA NetTESTER FAMILY USER MANUAL 10.3.1.1 Basic Test The basic test regime, as the name suggests, allows for simple tests with specified rate, duration and packet size(s). Two such tests, with independent parameters, may be run in sequence, allowing for a short 'go/no-go' phase, followed by a longer 'soak' phase.
  • Page 48 METRODATA NetTESTER FAMILY USER MANUAL Once the binary search has produced a result, it is normal to perform a longer test at this rate, although this may be disabled if the fastest possible execution is required. The longer test helps to eliminate results that are marginally higher than they should be, produced by a combination of the short test time used in the search phase and buffering within the network.
  • Page 49 METRODATA NetTESTER FAMILY USER MANUAL • Each element of the test for each packet size is awarded a pass or fail by comparison with the SLA, and these are combined to produce an overall pass/fail result. 10.3.1.3 Y.1564 Y.1564 [8] defines a testing methodology that is tied directly to the concept of the SLA, and which addresses the problem (with RFC2544) of excessively long testing times.
  • Page 50 METRODATA NetTESTER FAMILY USER MANUAL 11 OPTICAL TIME-DOMAIN REFLECTOMETRY (OTDR) TESTING The unit can be used with a range of special SFP single-mode fibre modules, supplied by Optical Zonu [9], which have an integrated Optical Time-Domain Reflectometry (OTDR) measurement facility. With an OTDR SFP module fitted, the...
  • Page 51 METRODATA NetTESTER FAMILY USER MANUAL 12 IN-SERVICE PERFORMANCE MONITORING In-Service Performance Monitoring (normally referred to simply as performance monitoring, or PM) is the process of ensuring that a service continues to meet the performance requirements (SLA) once it has started to carry live traffic.

    TWAMP messages. This is controlled globally, and can only be changed from the Advance Mode user interface. For strict compliance with RFC5357, the NTP (TWAMP) option should be selected. Where the peer is a Metrodata product running software version 9.37 or older, the PTP (Y.1731) option should be selected. For Metrodata peers running newer software, either option may be used, but the same selection must be made on both units.

  • Page 126 METRODATA NetTESTER FAMILY USER MANUAL TWAMP OPERATION The diagram below shows a network configuration with a single generator using TWAMP to monitor the connection to three remote peer devices. In this application, the TWAMP Generator will send a test PDU to each remote peer at a rate of 1 packet per second to measure the round-trip latency, one-way jitter and the synthetic packet loss associated with the route to the peer.
  • Page 127 METRODATA NetTESTER FAMILY USER MANUAL The one issue with SLA monitoring is that SLA’s are typically defined over a long time period, for example 24 hours or 30 days. As an example, the latency may be defined as 95% of all frames must be within 100mS over 24 hours, which means that there could be 4320 latency violations before the SLA would be breached.
