Minutes of Working Group Meeting

CFHT Base Facility, Waimea

September 21, 2006




  1. Current Network Status
  2. On the early morning of July 27th, Hawaiian Telcom's fiber was damaged by a fire at Makaha which affected our Internet connection to non-edu sites. Service was switched to the Time Warner backup link. However due to routing issues, some Internet sites could not be reached. A temporary fix was put in place around 2:00 pm. The primary fiber path was restored early the next morning.

  3. Update of the SX TransPORT 10 Gigabit per second (Gbps) links and extension to MK - brief update
  4. Fiber work for the extension has begun in Waimea and Hilo. On the equipment side, there has been talk of using a couple of Juniper routers, but so far no definite plans have been made. Pui Hin pointed out that if a Juniper router were to be installed at CFHT, it would be too expensive for MKOCN to provide a backup. Pui Hin will continue to work with UH-ITS.

    In addition to the 1 Gb link through Waimea -- as part of the effort to extend the SX TransPORT to MK -- UH-ITS is working with Hawaiian Telcom on a plan of paying an up-front amount of money now in order to reduce the future cost of the connection between the Summit and Hilo, and between the Summit and Waimea.

  5. Gigabit switched network for the MK Summit
  6. The purchase of new switches has been delayed. Pui Hin is hoping to wait for the decision on what will go into CFHT and IfA Hilo for the 10Gb extension, to be sure that what we purchase for the Summit and backup equipment will work with the new links.

    However, there is now some urgency in putting the Summit Gigabit switched network in place. Some of the Cisco 7200 series of routers -- mostly what is installed at the observatories -- will reach "End of Support" by Cisco in December. For the Summit, Pui Hin suggested the Cisco 3560 switches for an inexpensive replacement of the Cisco 7200 series routers at the observatories. The current plan is to replace the 7206 VXR at the Summit Communication room with a Cisco 3750. Since we don't have any plans to deploy OSPF among the observatories on the Summit, the observatories may choose to purchase their 3560 switch with the Standard software image. It will be possible to buy the enhanced IP service software module at a later time.

  7. Next meeting
  8. Thursday, December 14, 10:00 am, at CSO Hilo Facility.
Following the Network meeting, there was an impromptu System Administration session.
