New Features in Release 2.3
RN-001029-02, Release 2.3, Rev 00 7
SIP IP Phone Models 9143i, 9480i, 9480i CT and 5i Series Phones Release Note 2.3
Link Layer Discovery Protocol for Media Endpoint Devices (LLDP-MED)
In Release 2.3, the IP Phones support Link Layer Discovery Protocol for Media Endpoint Devices
(LLDP-MED). LLDP-MED is designed to allow for things such as:
• Auto-discovery of LAN policies (such as VLAN, Layer 2 Priority and Diffserv settings)
leading to "plug and play" networking.
• Extended and automated power management of Power over Ethernet endpoints.
• Inventory management, allowing network administrators to track their network devices, and
determine their characteristics (manufacturer, software and hardware versions, serial / asset
number).
On the IP Phones, LLDP-MED performs the following:
• Supports the MAC/PHY configuration (e.g. speed rate/duplex mode).
• Supports VLAN info from the network policy; this takes precedence over manual settings.
• Allows you to enable/disable LLDP-MED if required.
• Allows you to configure time interval between successive LLDP Data Unit (LLDPDU)
frames.
• Allows LLDP packets to be received from the LAN port and allows them to reach the PC Port.
• Allows the phone to use the location information, Explicit Congestion Notification (ECN)
Emergency Location Identification Number (ELIN), sent by the switch, as a caller ID for
making emergency calls.
You can enable or disable the LLDP-MED on the IP Phones using the configuration files, the IP
Phone UI or the Aastra Web UI.
Network Features
Note: If the phone receives location information in ECN ELIN format
(10 to 25 numeric string), the phone replaces the caller ID SIP header
with the ECN ELIN value and the SIP URI does not change. The phone
determines if this is an emergency number by checking the emergency
dial plan configured on the phone.
