National LambdaRail


From the NLR Interview Brochure:

National LambdaRail (NLR) is a high-speed, fiber-optic network infrastructure covering 12,000 miles and 21 states across the U.S. Owned by the U.S. research and education community, NLR does not impose any restrictions on usage, as do commercial carriers, offering users total flexibility and control. With a total capacity of 1600 Gbps, production 40G implemented and planning underway for 100G, NLR is the cutting-edge network platform for a wide range of advanced research projects and public-private partnerships.

Establishing an Endpoint

Membership Information

Once this is complete, the NLR NOC <> will work with you to setup the appropriate accounts and access needed for your project.

Sherpa Account

From the !FrameNet documentation:

Those interested in using the Dynamic VLAN Service can contact NLR Experiments Support Services (ESS) at <>. The ESS will work with you to make sure DVS fits your needs, and shepherd the administrative and financial process.

The process for requesting Sherpa access right now is fairly informal. Currently there are no rules/regulations/procedures outlined for requestingSsherpa access. For now send a request to the globalnoc <>.

VLAN Provisioning Within FrameNet

This section outlines provisioning within Sherpa. For the complete procedure of provisioning a VLAN between two sites see ConnectivityGuidelines.

Once you have an Sherpa account you will be able to provision VLANs between site's endpoints using the !FrameNet VLAN provisioning webpage.

There only needs to be one organization with Sherpa access with permission to provision VLANs on both endpoints.

You cannot create VLANs to arbitrary endpoints locations, but only to those endpoints which you have permission to access. This is a manual process in which someone contacts the Sherpa account holders at both endpoints and gets permission. Once that permission step has been accomplished, the other endpoint will show up as a valid choice in the Sherpa "Z End" dialogue.

Required Topology Info

  • Your endpoint's name - will look like[Gi9/2]
  • Your partner site's endpoint's name
  • The VLAN ID that you and your partner site dedicated for this connection.

Creating the Circuit

  • Step 1 (Edit Vlan): it is fine to request a particular VLAN tag; the system will report quickly whether it is available.
  • Step 2 (A End): specify your campus's endpoint
  • Step 3 (Z End): specify your partner campus's endpoint.
  • Step 4 (Vlan Path): Unless you and your partner site have specific path requirements you can use the Recommend Path button.
  • Step 5 (Root Bridge): Choose the root bridge for the VLAN.

VLAN Translation

If VLAN Translation is required NLR may be able to accommodate on a case by case basis.

Multipoint VLANs

NLR currently supports creating multi-point VLANs through Sherpa.
