In addition, you must be using an IP Phone that supports it (LPE and qualified phones do) or a Windows OS that supports it (Windows 8.1 or above) if you are using soft phones only. Note: You must utilize LLDP-MED on your switches for Option 2 above, as the Skype clients obtain that information from the LLDP-MED tags on the network. If you have unique IP subnets but can’t keep the subnet within the physical bounds of an ERL then enable LLDP and utilize option 2 above. It may not seem like a big deal but the whole goal of E9-1-1 is provide as accurate of location information as possible, so if you can’t ensure subnet uniqueness and subnet geofencing then you’ve broken E9-1-1. As an aside – IPv6 doesn’t allow that kind of shared-subnet-uniqueness anyway, so network engineers should not be fighting the inevitable (IMHO). Fixing that problem is painful and hard work to accomplish, but the rewards are plentiful because it removes other configuration blockers that arise for Skype4B/Lync when subnet-uniqueness is not available. Note: You could technically use Option 2 and forgo Option 1 and identify ERLs by switch information, but the shared-subnet-uniqueness will still be a problem for you if not remediated.

Utilize the switch port ID or switch MAC address to identify the ERL and don’t use subnets.Utilize unique IP subnets within each ERL and ensure IP subnets are unique across all sites, OR….With the two caveats above in mind, you have two options to get around these issues: As soon as you create the second subnet & location, the first location becomes inactive and thus completely negates E9-1-1 location information you had previously entered.Īdditionally, the client sends the distinguishing subnet ID to LIS WS within the web service communication, so the fact that a NAT is in place is completely irrelevant – NAT will change the SrcIP on the Layer 3 traffic between client and server but it doesn’t change the information within the web services request. The issue is that you can only have one that is active. Note: It’s not that you can’t define two separate locations for a single subnet because you very much can. The major issue with this approach is that LIS is global so you cannot define two separate locations within LIS for a single subnet. To differentiate on the WAN and keep Layer 3 routing alive, network engineers use Network Address Translation (NAT) to ensure that traffic can route between the two locations. In that case, a single subnet (10.0.100.0/24) might be used at a site in the US and also within a site in the UK. This type of scenario tends to exist in medium to large organizations that have grown by acquisition. Thus, an IP subnet used within ERL 2 must not be used for any client that may exist outside the physical bounds of ERL 2. If you intend to use IP subnets for location recognition, you must ensure that an IP subnet does not leak outside the physical bounds of the defined ERL it is serving. You can’t use subnets if a single subnet exists in two separate physical locations.

Sorry…don’t shoot the messenger! We know from the previous post that we need to have two ERLs per floor but we also know that the client must send an identifying network attribute to LIS so that a single, definite location can be ascertained. Just when you thought that all the requirements were in place, there comes one more. Today, we begin to take our emergency requirements and turn them into a logical configuration within Skype4B.
