Netbox

Netbox is a DCIM (DataCenter Infrastructure Manager) capable of managing inventory of Sites, Racks, Devices, Ports etc...

In our case we use Netbox to store information about utilization of physical interfaces.

There are some strong assumptions that we make:

  • all the nodes have a fixed configuration that does not change often over time
  • the only point where operators can allocate interfaces is GAP.
  • we do not manage the legacy Juniper network

Network hardware

The new routers have a static hardware configuration which is dependant from the TIER. The following table summarize it:

Tier Chassis Control plane Switching fabric Linecard
Tier1 SR7s 2x CPM2-s 4x SFM7-s 2x XCM2 - 2x XMA2-s (36p QSFPDD)
Tier2 SR7s 2x CPM2-s 4x SFM7-s 2x XCM2 - 2x XMA2-s (36p QSFPDD)
Tier3 TBD TBD TBD TBD
Tier4 TBD TBD TBD TBD
