Local IT

This may be you, your department, BMC-IT or client support at UUIT or any other organisation at the university, depending on where you work.

BMC-IT

Contact helpdesk@bmc.uu.se

UUIT

Contact Domainmaster (DNS/DHCP/TFTP), Netsupport (Network), IRT (Security) or UU helpdesk (everything else).

Responsibilities

These reflect how it is usually done, but are not carved in stone

  • All usage on the VLAN/subnet
  • Local security on the VLAN/subnet
  • Identity of the different computers
  • Request change in router filter
  • Physical network copper and fiber.
  • Buy switches
  • Request change of VLAN configuration of switch ports
  • Patch network in cross connect cabinets
  • Keep documentation of cross connect cabinet patches
  • May help Local IT track down rogue computers
  • Router and router filter (Netsupport)
  • Perimeter Firewall (Security division)
  • Install, configure, replace and maintain switches (Netsupport)
  • Security tracking (Security division)
  • TFTP, DNS and DHCP for UU (Domainmaster)
  • May help Local IT track down rogue computers (Netsupport and Security division)
Install a new network socket (or move an existing network socket) Installation of a new socket costs around 3000 SEK for a double socket. It depends on the amount of work. Several sockets in one room is less work (cheaper) per socket than one single socket. Please write the following information in the mail:

  • Room number
    Example A1:123d
  • Other requests
    Example right side, near the window
  • Who to charge (Kostnadsställe)
    Example 123ABC

If you want to connect the network sockets to the network (and not only telephone) then also supply:

  • Which VLAN at BMC you would like to use.
    Example Vlan680 "BMC-Data"
  • If you want one or two sockets to be connected. If you only want one, clarify which socket to activate.
    Example Left, right or both
Directly connect two network sockets Two network sockets connected to the same cross connect cabinet may be directly connected with two patch cables in the cross connect cabinet. Just send an email to helpdesk@bmc.uu.se with the network socket and cross connect cabinet identifiers.
New power socket Talk to Bo Ejdesjö at BMC. Will cost money. Hyresgästanpassning.
New pillar with power and network sockets Talk to technical service at BMC. Free of charge AFAIK.
All about fixed telephone Talk to teleservice at university. Will cost money.
Activate network socket () BMC-IT does the cross connect cabinet patching and requests VLAN change.

Please write the the following information in the mail. (Read more in FAQ on how the network sockets are identified.)

  • Cross connect cabinet identifier
    Example A1-D101-11-17
  • Network socket identifier
    Example A1.202:1
  • VLAN name or number
    Example Vlan664 "NEURO"
  • If it is a double socket identifier, clarify which socket to activate
    Example Left, right or both

Here is an example how a mail could look like:

Deactivate network socket Send a message to BMC-IT with the following information in the mail. (Read more in FAQ on how the network sockets are identified.)

  • Cross connect cabinet identifier
    Example A1-D101-11-17
  • Network socket identifier
    Example A1.202:1
  • If it is a double socket identifier, clarify which socket to deactivate
    Example Left, right or both
Change VLAN in an already activated socket Send the request to BMC-IT. Please write the following information in the mail:
  • Cross connect cabinet identifier
    Example A1-D101-11-17
  • Network socket identifier
    Example A1.202:1
  • VLAN name or number
    Example Vlan664 "NEURO"
  • If it is a double socket identifier, clarify which socket to deactivate
    Example Left, right or both

Here is an example how a mail could look like:

UUIT Netsupport will do the configuration of VLAN in switch.
Server room access in D11:0 May give temporary guided access Contact UUIT for permanent access to your rack
Faster network Upgrades to 1 Gbit/s are available in most cross connect cabinets. Request upgrade from Fast Ethernet to Gigabit by sending a mail to helpdesk@bmc.uu.se with the following information written in the mail:
  • Cross connect cabinet identifier
    Example A1-D101-11-17
  • Network socket identifier
    Example A1.202:1
  • If it is a double socket identifier, clarify which socket to upgrade
    Example Left, right or both
If you need 10 Gbit/s contact BMC-IT together with UUIT Netsupport. This is available in a few cross connect cabinets.
Order a new VLAN/subnet First find out how many IP you need
(Remember to fix DNS and perhaps DHCP, router filter settings, and possibly perimeter firewall settings)
BMC-IT may be aware of spare ranges or networks on the way of being decomissioned that can be reused. We do not want to create a lot of small VLANs if not needed. Contact UUIT Netsupport to get new subnet and VLAN assignments
Campus router filter settings (Cisco) Figure out what you need And let UUIT Netsupport configure the router filter
University perimeter firewall settings (Fortigate) Figure out what you need And let Security Division configure the firewall
DNS Local IT can do this but should not. Use the BlueCat IPAM system at UUIT.
DHCP Local IT can do this but should not. Use the BlueCat IPAM system at UUIT.
TFTP / PXE-boot Local IT can do this Use the UUIT TFTP-server.
Finding a rogue computer The responsibility belongs to Local IT Arpwatch service is available. Manual check in router and the Upunet Tracking Database (NetDB) service
Finding used and unused IP-addresses Keeping track of who is using what. Registration and removal of IP in DNS. Arpwatch service is available. Manual check in router, Bluecat (IPAM) and the Upunet Tracking Database (NetDB) service
Router and uplink bandwidth Linkstatus graphs available for BMC Netstat graphs available for UU
Magic network problems Contact your Local IT And then let Local IT contact UUIT Netsupport
My windows server does not work Contact your Local IT
Eduroam do not work on my client or in general Local IT may help with client configuration Broken wireless hotspots should be reported to UUIT Netsupport
Wireless (Eduroam) coverage is low in some rooms or corridors () Contact BMC-IT to discuss what can be done. All office corridors should have coverage, or at least they originally had. Over the years more and more equipment is using the wireless network or the free frequencies used by the wireless network for different purposes.
  1. BMC-IT can together with IT-division order more hotspots to get better coverage. This is a payed for by the tenant (department). Send a mail to helpdesk@bmc.uu.se with the following information
    1. A list of room numbers with low coverage
    2. Who to charge (Kostnadsställe) Example 123ABC

    An approximate cost would be 3000 SEK for the network socket and 5000 SEK for the wireless access point. Current delivery times are around two months for a new network socket to be installed and the wireless access point to be delivered and set up.

  2. With a start in 2018 the IT-division will upgrade the network at BMC to a new generation of wireless hotspots. Most of the switches and wireless hotspots will be upgraded. It will take some time for this to be completed.

  3. If you have a laptop computer with no ethernet port you can use a USB-adapter for attaching the wired network to the computer.

  4. Some laboratory instruments and door locks also use the same free frequences. It is not much we can do, the equipment manufacturers and the landlord / facility providers do not always have the same priorities as us (IT-support and network users).

UUIT Netsupport may together with BMC-IT install new wireless hotspots. This may cost money. All public rooms for students should have coverage.
I need a network cable Contact your Local IT
The IRT-group has disconnected my computer from the Internet! Contact your Local IT to fix your computer Let the Local IT contact the IRT-group to open the router filter when computer is fine.
My Internet do not work! Help! Check how to find the cause of the problem here. Finding configuration problems in the local computer is a job for Local IT. If it should work but get no link then perhaps switch port is broken. Contact helpdesk@bmc.uu.se. This might be a magic network problem. Then contact UUIT Netsupport.
