Hey guys. I don't have an E911 requirement for my Lync deployment, since our local, on-campus police receive 911 calls. They then conference in a PSAP if the call is meritorious for a public safety escort.
However, I still have to get building/room info out of my ethernet switch ports and present it to the on-campus police computer assigned the 911 phone number. The cmdlet in the subject line implies that Microsoft has an "SNMP application url" in mind that they can simply feed a MAC address to in order to query for the switch port. Do you know what Microsoft uses for their SNMP?
Secondly, is there a way to display this "building/room" info grabbed from my switch ports on the 911 computer at our police station?
I'm gonna e-mail Thomas and make sure he sees your question... I'm clueless about Lync :)
Thanks @Don for pointing me to this question!
IIRC, you need LLDP-MED to so this. LLDP is Linc Layer Discovery protocol (See http://en.wikipedia.org/wiki/Link_Layer_Discovery_Protocol for details of LLDP itsself).
Having said that, You should probably ask these questions over at the Lync forums as they're not really powershell question as such, but more of a 'how does E911 work' type question. See: http://social.technet.microsoft.com/Forums/en-US/ocsvoice/threads for more help. You should get great feedback there.
Hope this helps and sorry I can't answer all the info.
