  1. MXK TrainingModule 6Operational support tools

  2. Operational Support Tools This modules covers Overview of available debug facilities Gathering statistics Bridge forwarding table ONT alarms MTAC tests Upgrading Emergency procedures

  3. Available facilities syslog, alarms, traps etc Hardware related information Fans, temperature etc System logs Alarms Traps

  4. Hardware related information To read shelf power status zSH> shelfctrl monitor Shelf uptime: 4 hours, 13 minutes Shelf Monitor CPLD version: 0.5 Shelf Monitor Firmware version: 0.5 Outlet temperature sensor: 30 degrees C (normal) Fan Power A: normal Fan Power B: normal Power Supply A: failure Power Supply B: normal Fan status: OK. System: Critical alarm set. Card a: Critical alarm set.

  5. Hardware related information, cont’d Show card information zSH> slots 1 Type : MXK 4 PORT GPON Card Version : 800-02586-02-A EEPROM Version : 1 Serial # : 2062628 CLEI Code : No CLEI Card-Profile ID : 1/1/10205 Shelf : 1 Slot : 1 Software Version: MXK State : RUNNING Mode : FUNCTIONAL Heartbeat check : enabled Longest hbeat : 52 Fault reset : enabled Uptime : 4 hours, 15 minutes.

  6. Alarms To show current alarms, enter: zSH> alarm show ************ Central Alarm Manager ************ ActiveAlarmCurrentCount :12 AlarmTotalCount :14 ClearAlarmTotalCount :2 OverflowAlarmTableCount :0 ResourceId AlarmType AlarmSeverity ---------- --------- ------------- 1-a-1-0/eth linkDown critical <output omitted> 1-a-9-0/eth linkDown critical 1-a-10-0/eth linkDown critical 1-a-11-0/eth linkDown critical system power_supply_a_failure minor 1-1-1-0-gponolt/sn-2 gpon_unassigned_serial_number warning

  7. Bridge statistics To enable on-demand statistics for a given bridge interface, use: zSH> bridge stats enable ethernet4-500/bridge Show total number of packets traversing the interface: zSH> bridge stats Interface Received Packets/Sec Transmitted Packets/Sec Name UCast MCast BCast UCast MCast Bcast Error ethernet4-500 0 0 0 0 0 0 0 Show rate, in packets per second, for a bridge interface: zSH> bridge rates Interface Received Packets/Sec Transmitted Packets/Sec Name UCast MCast BCast UCast MCast Bcast Error ethernet4-500 0 0 0 0 0 0 0

  8. Forwarding table Note that asymmetric bridge uplinks do not record MAC addresses, but the downlinks do. For TLS bridges, utilize normal layer two troubleshooting techniques. Each TLS interface will record MACs. zSH> bridge show Type VLAN Bridge St Table Data -------------------------------------------------------------------------- tls Tagged 500 ethernet4-500/bridge UP D 00:0c:76:16:da:4d

  9. Port command Use the port command to up or down a port change configuration of a port show the status of a port show statistics for a port set a description for a physical port zSH> port down 1-a-10-0/eth zSH> port status 1-a-10-0/eth zSH> port show 1-a-10-0/eth zSH> port stats 1-a-10-0/eth port <up|down|bounce|config|show|description|status|stats <add|modify|delete|find> > <interface name/type> <config options> <description_text>

  10. IP ARP table The local IP ARP table can be viewed by entering: zSH> ip arpshow LINK LEVEL ARP TABLE destination gateway flags Refcnt Use Interface -------------------------------------------------------------------------- 00:0c:76:16:da:4d 405 1 154 ethernet4-10 0 00:03:ba:09:59:41 405 1 195 ethernet4-10 0 00:01:47:01:ae:18 405 1 2658 lo 0 -------------------------------------------------------------------------- 6 routes, 3 arp routes --------------------------------------------------------------------------

  11. IP PING and TELNET PING and TELNET is available from the console. mxk# ping PING 64 data bytes !!!!! ---- PING Statistics---- 5 packets transmitted, 5 packets received round-trip (ms) min/avg/max = 0/0/0 mxk# telnet

  12. ONT alarms A connected ONT will send in alarms to the MXK, these can be viewed by using zSH> gpononu alarms 1/1/1 1/1/1 ONU Active Alarms PptpEthUni 0x0401 LanLos PptpEthUni 0x0402 LanLos PptpEthUni 0x0403 LanLos PptpEthUni 0x0404 LanLos

  13. ONT statistics A connected ONT can gather statistics from Ethernet ports zSH> gpononu statistics 1/1/1 1/1/1 ONU Statistics Ethernet Performance Monitoring History Data - Port 1 59 Interval Time 0 FCS Errors 0 Excessive Collision Counter 0 Late Collision Counter 0 Frame Too Long 0 Buffer Overflows on Receive 0 Buffer Overflows on Transmit < output omitted > 0 Internal MAC Receive Error Counters

  14. MTAC Testing The MXK-MTAC/RING-ENH card is able to perform Metallic Loop Testing (MLT) without an external test set. The MXK-MTAC/RING-ENH card comes with an integrated test head, thus, each shelf has its own dedicated test head. This means user can now communicate with each shelf concurrently to perform test out sessions. Typical tests takes 1-2 seconds.

  15. MTAC Testing • Tonegeneration • Transhybridloss • Drawandbreakdialtone • Dcfeedselftest • Onandoffhookmeasurement • Ringingselftest • Ringingmonitor • Meteringselftest • Transmissionselftest • Howlertest • Readloopandbatterycond... • Tests include • foreigndcvoltage • Foreignacvoltage • dcloopresistance • 3elementresistance • 3elementcapacitance • receiveroffhook • distancetoopen • foreignaccurrents • ringerequiv • dtmfandpulsedigitmeasur • noisemeasurement

  16. MTAC Testing • Test syntax mtac-linetest<portaddr> <mode> <testid> [<linetype>] [force] [p1] [p2] [p3] [p4] [p5] zSH> mtac-linetest 1/1/1 lookoutdistancetoopen shdsl force

  17. Upgrading a system Steps Download software and release notes Carefully read release notes Back up old configuration and software Download software to MXK flash Replace the RAW file (bootfile) on the flash card Reset and reboot

  18. Download software and release notes From, open Service and Support then Downloads You need to have a valid Zhone Web user account Download the selected software and release notes

  19. Carefully read release notes Carefully read the release notes of the selected software, it contains important information!

  20. Back up old configuration and software Back up the old configuration using: zSH> dump network <host> <filename> Create the file locally zSH> cd onreboot zSH> dump file restore To create a software backup, create a local directory on the flash and copy all *.bin files to it.

  21. Download software to MXK flash Unpack the *.tar.gz file and publish it with your TFTP server Download the *.bin files to your MXK system You can also download the *.bin files for every card you have, but if you later insert a different uplink or line card you need to download the accompanying .bin file for the card

  22. Replace the RAW file (bootfile) on the flash card Replace the RAW (bootfile) file zSH> image flash <binary RAW file> 1

  23. Reset and reboot Reset and reboot the system zSH> set2default The system will now clear the database, reboot and use the new software When the “restore” file is found, the MXK will read back the configuration and do a secondary reboot

  24. Zhone emergency mode The Zhone utility mode allows the operator to upgrade, format and reinstall the uplink without a working firmware. This mode is normally not used, but it is a very valuable tool if needed. To enter the utility mode, connect to the serial craft port and reboot the unit. Wait for the message “Loading raw file” then enter “zhone” in the console. This will effectively halt the boot process and return a command prompt. At this stage only the 10/100 management port and the serial port are accessible. Add a temporary address and route to the 10/100 management with zSH> ipconfig zSH> route add
