6. Smartbits Hardware Overview

7. Different Linecard Types Traditional vs. Smartmetrics Terametrics For SNT, Smartmetrics cards can have many streams, and Traditional cards can only have 1 stream. Terametrics cards are Smartmetrics+, they have everything the Smartmetrics cards have plus they have Layer4-7 processing. Traditional Cards (mainly on smb-2000) SX-7410, LAN-3100, LAN-3200, AT-9155, AT-9622. Only gives per PORT statistics SmartMetrics Cards ML-7710, LAN-3101, LAN-3201, LAN-3310. Gives per port and per stream statistics Terametrics Cards (routing, L4-L7, + rates per stream capability) LAN-33XX, XFP-3731 (10G)

11. Ways to Run Smartbits in Production SNT+ Configuration file driven (*.SNT and *.SAI) Most widely deployed driver Ideal for short duration batch mode style testing Cisco Products = Cat6k, Cat4k, WNBU, ATG (New ATG product by Hong Lu) SNTtc Command-line driven Ideal for dynamic configuration file creation Modular: Supports Spirent TestCenter, Avalanche and the SmartBits platforms Cisco Products = 7600 (SPA), DC3, CRS SNT Command-line driven Only supports data-plane traffic on the SmartBits platform Cisco Products = Cable, MDS, ATG, DSBU, VTG Custom Scripts Generally written by Cisco TE, typically > 5 years old, done prior to SNT+ creation. Not recommended by Spirent due to support challenges Cisco Products = 7x00 Routers Use sentence case in bullet points, DO NOT use all caps, or initial caps. Use no punctuation at the end of sentences. Use bold or italics for emphasis, but not all the time. Try not to have more than five major bullets of text on a page, and not more than 8 lines of text. Don’t try to cram everything into one slide -- make major points on the slide and use notes pages or your voice track to add in the details.

13. My Topology for Demonstration

14. Installation + Start Download snt.zip from www.gospirent.com/mfg FTP snt.zip to your Sun workstation Simply copy this zip file to where you want to install it on the workstation. Extract the file with "unzip snt.zip" Set the LD_LIBRARY_PATH to point to the *.so file that is included: Example = setenv LD_LIBRARY_PATH ${LD_LIBRARY_PATH}:/usr/autoprog/foxconn/snt Set permissions with “chmod 777 *” on snt directory and contents To Start = ./sntx.x <chassis ip>

15. Configuration – Reserving Ports conf terminal port 0 reserve 1/4/1 exit port 1 reserve 1/4/2 exit

16. Configuration for Router UUT General Tip = All commands are “autocomplete”, meaning you do not have to type the whole word. “sh por” is the same as “show port” Note = framerate can only be set on stream level for certain cards (lan-33xx). For older cards (i.e. lan-3101 or smb-2000 cards) rate is set on the port level config t port 0 packetcount 10000 # sets port to generate 10,000 packets stream create 1 # create emulated device on logical port 0 stream 1 # enter configuration mode for stream (emulated device) macdest arp # enables arp resolution for destination MAC, required for routers ipsource 20.1.1.2 # sets source ip address of emulated device ipdest 30.1.1.2 # sets destination ip address of emulated device packetsize 512 sets packet size for emulated device to transmit framerate 10000 # sets frames per second to generate, actual rate would be fps * frame size * 8 (to convert to bits) or 10000 * 512 * 8 = ~40mbps Exit port 1 packetcount 10000 stream create 1 stream 1 macdest arp ipsource 30.1.1.2 ipdest 20.1.1.2 packetsize 512 framerate 10000

17. Configuration for Switch UUT config t port 0 packetcount 10000 stream create 1 # create emulated device on logical port 0 stream 1 # enter configuration mode for stream (emulated device) macsource 00-00-00-00-00-01 # sets source mac address for traffic macdest 00-00-00-00-00-02 # sets destination mac address for traffic, arp not required when testing a switch packetsize 512 framerate 10000 port 1 packetcount 10000 stream create 1 stream 1 macsource 00-00-00-00-00-02 macdest 00-00-00-00-00-01 packetsize 512 framerate 10000

18. Show Commands

19. Run and Results SNT> run port all # runs all the ports configured in the test for the duration defined in the ports statement SNT> run port 0 # runs only port 0, no other ports will generate, all ports still receive SNT> run port 0-1 # runs only ports 0 through 1. If there were 10 ports in this test, only 0- 1 would generate traffic SNT> show count # shows port counters only Pt#/Stream# TxFrames RxFrames RxBytes RxTriggers OverSize UnderSize CRCErrors 0 1000 1000 516000 0 0 0 0 1 1000 1000 516000 0 0 0 0 SNT> show bcount # shows stream counters, more details on next slide Pt#/Stream# TxFrames RxFrames RxBytes RxTriggers OverSize UnderSize CRCErrors 0 1000 1000 516000 0 0 0 0 (1/4/1) 1 1000 (1/4/2) 1 1000 1 1000 1000 516000 0 0 0 0 (1/4/2) 1 1000 (1/4/1) 1 1000 SNT> clear counters #erases port and stream counters

20. Port Results vs. Stream Results A port can have multiple streams. A stream is defined as an individually trackable item usually with unique attributes like a different source ip address. Benefit : Allows for more detailed pass/failure analysis Example : The below topology shows two Smartbits ports testing x number of UUTs, in this case UUTs are IP phones (current Foxconn configuration). The 3rd UUT is failing

21. Internet Mix (Imix) Traffic Traditionally, Cisco runs three separate tests at different frame sizes, i.e. 64, 512, 1518. Some groups have changed to one test, running a mixture of framesizes, modeled after a realworld network. IMIX is defined as a 7:4:1 ratio of 64:512:1518 byte packets. This means that for every 12 packets, 7 are 64 bytes, 4 are 512 and 1 is 1518. This is another example of how to utilize streams Example: port 0 reserve 1/4/1 packetcount 100000 stream create 3 stream 1 packetsize 64 framerate 7000 stream 2 packetsize 512 framerate 4000 stream 3 packetsize 1518 framerate 1000

22. Other Configuration Options General + Root Prompt Commands help or ? Displays list of available commands at that prompt clear config Deletes running configuration config <filename.cnf> Loads new configuration write <filename> Saves existing configuration to file, .cnf automatically added to filename exit Returns back one prompt end Returns back to root prompt Port level configuration menu speed Set port transmission speed (10/100/1000 Mbps, autoneg) duplex Set port transmission type (full/half duplex) phyint Set physical interface for dual-media 1G (copper/fiber) packetcount Change the # of packets to send pattern Set packet payload, default is 0000 show Show port and stream level parameters for current port exit | end Return to main command level

23. Unix No Nos Cautions for UNIX DO NOT DO CTRL-Z on SNT. CTRL-Z is a standard Unix operative to put the foreground job into the background. If you accidentally do this, snt will disappear type “jobs” to see how many SNT’s are stopped you must type “fg” to get back each snt you put in the background ( fg is unix for “foreground” ) If you find SNT is not connecting, and you may have done some strange things like CTRL-Z or prehaps started many SNT sessions you did not want, use “astop snt” to get rid of them all.

24. Smartbits Hardware No Nos Smartbits cards are NOT Hot-Swappable. Power OFF the Smartbits chassis if you want to swap cards. Smartbits cards are static-senstive, so use of a grounding strap is recommended.

25. SNT Firmware Requirements

26. SNT Firmware Requirements How do you check what is currently installed? The text (Click here to add text) and title (Click here to add title) placeholders are set where they should be, DO NOT change or delete them. They are there for a reason, and when applying different templates they automatically format to the template formatting. Text slides ? there are two placeholders for text. The first placeholder is for the title of the slide, font is Arial, Bold, 36 point, color is orange. Titles should be initial cap, except for articles and conjunctions (a, an, and, but, for, nor, it, to, the), like in a newspaper headline. Try to stay within one line in the title, DO NOT use more than two.
