Network Monitoring

Room Tags

Every room at CERN is identified by a tag of the format Building/Level-ID. For example the DAQ barrack is 887/R-S10. The tag can be found from http://maps.cern.ch.

Switch Assignments

Landb virtual outlets for NP04.

Used when requesting connections in landb (network.cern.ch). We chose not to map each NIC on a computer to a specific port on the NP04 DAQ switches. Instead we map to a service. Not having a physical mapping between computer NIC and switch port make the outlet "virtual".

  • NP04-IP11/01, 0887 R-S10 - Computers in NP04 Router in DAQ barrack. 10 Gb SFP+ connections. We use direct attached cable for these connections.
  • NP04-IP12/01, 0887 R-S10 - 1 Gb SFP fiber connections. Devices (WIBs and SSPs) on the cryostat. Located in DAQ barrack.
  • NP04-IP13/01, 0887 R-S10 - 1 Gb RJ45 copper connections. For slower DAQ connections. Located in DAQ barrack.
  • NP04-IP14/01, 0887 R-S10 - COBs/RCEs in NP04 Router in DAQ barrack. 10 Gb SFP+ DA connections. We use direct attached cable for these connections.
  • NP04-IP1/01 - Located in detector ground rack area.

To get started Marc Collignon selected service names for us. "FYI, to start quickly, I have chosen to start the service name like this : IP1 to 10 for DCS services, IP11 to 20 for DAQ services and IP21 to 30 for EXP services."

Outlets

Outlets are the network plugs in the walls. They are grouped together in pairs. The status of each outlet can be viewed at https://landb.cern.ch/landb/portal/topology using the room tag information.
