  1. How do I configure the monitoring line card (10G-MONITOR)?

    Detailed instructions can be found in the following FAQ entry "How do I configure the monitoring line card (10G-MONITOR or M3-MONITOR) in the 10G-CLOS-ENCL or M3-CLOS-ENCL/M3-CLOS-ENCL-B and/or M3-SPINE-ENCL/M3-SPINE-ENCL-B switch(es)?".

  2. Can I assign a static IP address to the monitoring line card (10G-MONITOR)?

    Yes, as of switch firmware v0.9.8.8 and later, you can assign a static IP address to the monitoring line card via the TFT Color Display. Assign the static IP address as instructed in the FAQ entry "How do I configure the monitoring line card (10G-MONITOR or M3-MONITOR) in the 10G-CLOS-ENCL or M3-CLOS-ENCL/M3-CLOS-ENCL-B and/or M3-SPINE-ENCL/M3-SPINE-ENCL-B switch(es)?".

  3. Can I store/save the switch control settings on reboot?

    Yes, as of switch firmware v0.9.8.8 and later, it is possible to store (save) switch control settings after a reboot. Refer to the FAQ entry How do I store / save switch control settings on 10G-CLOS-ENCL or M3-CLOS-ENCL/M3-CLOS-ENCL-B or M3-SPINE-ENCL/M3-SPINE-ENCL-B switches?.

  4. How do I assign/require an administrator's password for access to the web interface?

    From the web interface, select Select Admin Password.

  5. I have forgotten the administrator's password for access to the web interface of the switch. How do I reset the password?

    Contact help@myri.com with the MAC address of the monitoring line card (silk-screened on the faceplate of the card), and you will be provided with a procedure to reset the administrator's password.

  6. How do I upgrade the firmware on the monitoring line card (10G-MONITOR)?

    Detailed instructions can be found in the section entitled Upgrade Monitoring Card Firmware.

    Also refer to How do we tell if the switch firmware is up-to-date?

  7. How do I upgrade the firmware on the switch line cards?

    Detailed instructions can be found in the section entitled Upgrade Monitoring Card Firmware.

  8. How do we tell if the switch firmware is up-to-date?

    The following procedure will determine if the switch firmware on the monitoring line card and the switch line cards is up-to-date.

    1. From the web interface, click on Status->slot m, and check the value of firmware in the 10G-MONITOR section of the output. You should see something like: 
      firmware: v0.9.9.3 June 18 2007 13:52:58

    2. Check the latest version of shipfs.img on the ftp site

      http://www.myri.com/ftp/pub/xbar32/

    3. If the switch firmware on the monitoring line card is not up-to-date, upgrade the monitoring line card firmware as detailed in the instructions in Update Monitoring Card Firmware.

    Another way to determine the versions of the line card firmware on all switch line cards is to grep the web output. 

    infusion%  lynx -source http://10.0.0.2/cgi/web.cgi\?all | grep firmware | grep Compiled
firmware version: M3 Switch Firmware v3.0 Type: LCMONITOR  Compiled on: Oct 7 2004 18:15:34
firmware version: M4 Switch Firmware v0.9 Type: 10G-2SW16LC  Compiled on: Nov 282005 16:49:45

  9. Can you provide examples of how to use the SNMP interface to the switch?

    Yes. Detailed examples can be found in the FAQ entry Does the monitoring line card in the 10G-CLOS-ENCL or M3-CLOS-ENCL/M3-CLOS-ENCL-B and M3-SPINE-ENCL/M3-SPINE-ENCL-B switches support SNMP?.

  10. Can I determine the serial number of the 10G-CLOS-ENCL switch enclosure from the web interface?

    Yes. Status -> Slot 23 (10G-POWER). The serial number listed is the serial number for the 10G-CLOS-ENCL switch chassis/enclosure.

  11. One of the connected switch ports is not illuminated in green/yellow on the TFT color display.

    In the following text, the term cx4_port is used to denote a 10GBase-CX4 switch port, the term quad port is used to denote a Xaui-over-ribbon-fiber switch port, and the term 10ge_port is used to denote a 10GBase-R switch port.

    Is the disconnected switch port (i.e., its virtual port is not illuminated on the TFT display) a cx4_port, quad port, or a 10ge_port?

    If a switch port is disconnected, follow these diagnostic procedures.

    1. Make sure that the switch firmware (MX-10G) has been installed properly on the host connected to that switch port. When the host software module has been loaded, the green LED on the host interface should be illuminated, and the TFT box associated with this switch port should be green. Check the kernel log (/var/log/messages) on that host for any errors that may have been encountered during the MX installation process.

    2. If the host software has been installed properly and the switch port TFT box is still not illuminated in green, try disconnecting and reconnecting the cable (at both ends). Does the switch port TFT box illuminate green?

      Note that the proper procedures for disconnecting/reconnecting a quad port cable are detailed in the following FAQ entry.

    3. If the TFT box does not illuminate green, try a different cable to see if the failure could be due to a damaged cable. Does the TFT box illuminate green if you use a different cable?

    4. If changing the cable does not result in the switch port TFT box illuminating as green, then try connecting the cable to another switch port on a switch line card. Does the green LED illuminate if the cable is connected to a different switch port? If yes, then it sounds like a hardware problem with the original cx4_port or quad port. Examine the switch counters data for that switch port for further information. Let's say that the disconnected cx4_port Y is located on the switch line card in slot X. Go to the web interface (Status - > Slot X - > cx4_port Y), and look for non-zero switch counters (e.g., signal lost or port down).

      If you have a loopback test device (10G-CX4-LOOPBACK or 10G-SR-LOOPBACK), then you can use this device to test for any problems at the switch port. After plugging the loopback test device into the switch port, you should see the value of signal lost go to 0 on the TFT display and/or the web output for that port, and the switch port should be displayed as green on the TFT display. If this does not occur, then there is a hardware problem with this switch port.

    5. If the switch port TFT box is still not illuminated in green, then it sounds like the problem is with the host interface. If you run mx_info on this host, does this host see the other hosts in the network? I.e., does the routing table information contain routes to all of the other hosts in the network? If not, refer to this FAQ entry for details. Refer to this FAQ entry for details on running the mx_pingpong hardware loopback test.
