Device Connectivity
Device move detection, in support of E911 Emergency Calling Services, is
critical to maintaining the accuracy of Customer Emergency Services ID
(CESID) information. With Release 5.2, the IP device location can be
automatically updated or the location can be monitored for manual update.
Detection of Layer 2 connectivity is through Spanning Tree Protocol (STP)
or Cisco Discovery Protocol (CDP). The Device Connectivity form
excludes Mitel Soft Phones, Symbol, DECT, and SpectraLink wireless
phones, DNIC telephones, CITELlink telephones, and Hot Desk Users.
Automatic CESID Update
Requirements and restrictions for Automatic CESID:
• All Layer 2 switches must report to CDP or STP or both (use one or
both protocols consistently on all L2 switches in the network)
• Designate Emergency Calls using Route Lists
• Not supported on hubs
• CDP or STP must be enabled on L2 switches
• Automatic CESID will not function during a backup or restore
Monitoring Device Move Detection
