Q:	(urgent) Technical queries: who will I contact: AMS-IX NOC or the Co-Location?
A:	The NOC contact page shows clearly who to contact in case of technical issues.

Q:	What is the procedure for changing equipment? (changing MAC address)
A:	At the AMS-IX switches port security is used to protect its infrastructure against unwanted packets and network loops. It prevents MAC addresses other than the locked MAC address from sending packets onto the AMS-IX platform. Previously, a port was shut for 10 minutes per violation. This has changed. Ingress (from the switch's point of view) traffic with a non-allowed source MAC address will be dropped. When carrying out maintenance that results in a change of MAC address (such as swapping equipment), a new MAC address must be learned or set for the switch port, and the old MAC address must be removed. The AMS-IX NOC will allow extra MAC addresses at the port until the maintenance has been completed. This should be done before starting the maintenance to prevent outages for the customer. The procedure for this is: Contact the AMS-IX NOC before commencing with the maintenance, either by e-mail (during office hours) or phone (during office hours or outside office hours for emergency maintenance) for allowing or setting an extra MAC address. Contact the AMS-IX NOC after finishing the maintenance to remove the old MAC address. We urgently request that factory-default MAC addresses are used. AMS-IX staff would like to be able to register changes and see the OUIs in order to correlate new issues to certain changes or certain router vendors.

Q:	We are IPv6 ready: How do we announce this to AMS-IX?
A:	Please send an e-mail to the AMS-IX NOC, whenever you are IPv6 ready. Please include the port (if you have more than one), your AS number and the IPv6 address(es) you plan on using. We can also register reverse DNS (PTR) mappings for the IPv6 addresses on the peering LAN. Just include the required mappings in your mail, or use the Change PTR RR form in the member's section.

Q:	Who will arange cable management?
A:	The party you have chosen, an AMS-IX Partner, co-location(s) or Layer2 Provider, will arrange cabling.

Q:	What is Link Aggregation?
A:	Also known as "trunking" (Foundry), "EtherChannel" (Cisco), or the official IEEE term "LACP / 802.3ad". Link aggregation bundles multiple parallel links between a pair of devices forming a single high-performance channel. See also the Link Aggregation page in the technical section. At AMS-IX, link aggregation is available for gigabit connections at all locations.
