## My IX port isn't working, what should I do?[​](#my-ix-port-isnt-working-what-should-i-do "Direct link to My IX port isn't working, what should I do?")

* If your IX port is a new install, schedule a Turn Up Call so we can enable port security and put it in our Production VLAN. Follow the instructions on the "Installation Completed" notification emailed to you, or contact your CSM for assistance.
* If your IX port was working, and is no longer working, open a Support Case from the Customer Portal so it can be routed to our Service Management Center for troubleshooting. Provide the CableID/Serial# and/or your Equinix assigned Peering IP address for a quicker resolution.
  * If you swapped out your equipment, open a Support Case and provide your new MAC address, and CableID/Serial# and/or Equinix assigned IP address so we can update our MAC filter.

## What are some of the key benefits of peering at Equinix?[​](#what-are-some-of-the-key-benefits-of-peering-at-equinix "Direct link to What are some of the key benefits of peering at Equinix?")

No. Equinix does not currently run peering discussions lists.

## Does Equinix validate the prefix advertised with the Black Hole community?[​](#does-equinix-validate-the-prefix-advertised-with-the-black-hole-community "Direct link to Does Equinix validate the prefix advertised with the Black Hole community?")

Yes. The RTBH prefix is a subset of the IRR-validated prefixes from the advertising ASN.

## Is this RTBH solution IETF-compliant?[​](#is-this-rtbh-solution-ietf-compliant "Direct link to Is this RTBH solution IETF-compliant?")

Yes. The Equinix RTBH feature is based on an [IETF draft standard](https://tools.ietf.org/id/draft-ietf-grow-blackholing-01.txt)

## Does the Equinix RTBH feature support IPv6?[​](#does-the-equinix-rtbh-feature-support-ipv6 "Direct link to Does the Equinix RTBH feature support IPv6?")

Yes. The feature supports IPv6. MLPE route server changes the next-hop IPv6 address to the Black Hole host (example 2001:2:4115:240) if your prefixes are tagged with BGP community 65535:666. The Black Hole host then responds to IPv6 Neighbor Discovery.

## What is the acceptable prefix by the MLPE servers for RTBH requests?[​](#what-is-the-acceptable-prefix-by-the-mlpe-servers-for-rtbh-requests "Direct link to What is the acceptable prefix by the MLPE servers for RTBH requests?")

Equinix MPLE route servers accept /32 IPv4 prefix announcements with BGP community tag for RTBH filtering.

## What physical connections or media types are supported on the IX ports?[​](#what-physical-connections-or-media-types-are-supported-on-the-ix-ports "Direct link to What physical connections or media types are supported on the IX ports?")

## Can a live interconnection service be physically moved from one cage or cabinet to another? How do I request this migration service?[​](#can-a-live-interconnection-service-be-physically-moved-from-one-cage-or-cabinet-to-anotherhow-do-irequest-this-migration-service "Direct link to Can a live interconnection service be physically moved from one cage or cabinet to another? How do I request this migration service?")

Physically moving one end of any live interconnection service is referred to as migration. This involves moving the A-side or Z-side of the service from one cage or cabinet to another within the metro.

To migrate an interconnection service, you must submit a request for scheduled maintenance. Gather details about the physical connection, the cages, and the maintenance schedule. Send this information to the region’s migration team. For details about submitting information to the migration team, and an overview of the workflow, see [Request an Interconnection Service Migration](https://docs.equinix.com/cross-connect/managing/migrate-interconnect-service.md).

* If the circuit is not live, you can use the Equinix Customer Portal to submit a de-install order and an install order with the new demarcation required. There is no need to contact the migration team.
* If internal patching is required, use the Customer Portal to create a [Smart Hands order](https://docs.equinix.com/smart-hands/ordering/sh-how-to-order.md), and choose the Move Cables order type.

## Does IX support Bidirectional Forwarding Detection (BFD) ?[​](#does-ix-support-bidirectional-forwarding-detection-bfd "Direct link to Does IX support Bidirectional Forwarding Detection (BFD) ?")

IX does not support Bidirectional Forwarding Detection (BFD) for [Multi-Lateral Peering Exchange (MLPE)](https://docs.equinix.com/internet-exchange/peering/ix-prod-mlpe.md). Support for BFD between bilateral peers is at the discretion of the participants.
