Thank you very much. Then comment below "The IODs for the SNMP are hardcoded into an XML. There is no way to add or modify the list." refers to the ability to use CER switch port location with non-supported switches?

Thank you. With Subnet ID, assuming manual config of the CER to define the subnets is required?  Using Subnet ID, does SNMP need to be configured on the non-supported switches to allow CER to pull information or is CER <--> CUCM the only communicatio...

Thank you.  A follow up, if using non-supported switches with CER using subnet based location, does CER need to be able to access the switches via SNMP or does CER get all information required from CUCM? Thanks again

Kevin - If using CER and CUCM via SNMP (non supported switches), will this support extension mobility?  Will CER be able to track the location of an extension that moves to another phone/subnet? Thank you
