cleaned up NLR FrameNet VLAN table, prepared links for VLAN details section

National Lambda Rail

Known Issues

  • Sherpa currently cannot be used to provision a VLAN that uses a port-channel interface (e.g.[Po1]).


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.


For a current list FrameNet's active VLANs see Note that this will not show reserved VLANs.

FrameNet Endpoints

Site Endpoint
SiteIndiana N/A (direct provision into FrameNet)
SiteWisconsin (TBD)


See SiteNlr/OpenFlowVlanNotes for information on these VLANs

VLAN 3705

This multi-point VLAN will interconnect all OpenFlow Campuses without using the OpenFlow Core Switches. See SiteNlr/OpenFlowVlanNotes#NLRmulti-pointVLAN for more info.

VLAN 3715

This multi-point VLAN interconnects all OpenFlow campuses by means of the NLR Core North VLAN. See SiteNlr/OpenFlowVlanNotes#NLROpenFlowCoreVLANs for more info.

VLAN 3716

This multi-point VLAN interconnects all OpenFlow campuses by means of the NLR Core North VLAN. See SiteNlr/OpenFlowVlanNotes#NLROpenFlowCoreVLANs for more info.

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 <>.

If your campus has their own dedicated NLR FrameNet port
You can directly ask NLR for Sherpa access to provision VLANs on that port.
If the campus connects through a regional and a shared FrameNet port
It would be up to the regional whether the regional chooses to grant access to the campus to do Sherpa provisioning on the FN port. You may need to request your Regional IT staff to provision FrameNet VLANs on your behalf.

VLAN Provisioning Within FrameNet using Sherpa

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

It is important to work with your Campus and Regional Netowrk (as well as your partner Campus and regional network) to negotiate a common VLAN ID.

Once you (or your IT contact at your regional) 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.

Multi-point VLANs

NLR currently supports creating multi-point VLANs through Sherpa.
