Ip Address Collision - NEC UNIVERGE SV9100 Manual

56
Be aware that the RTP/RTCP Layer 3 QoS setting is common to all signalling protocols so if there are
several VoIP protocols being used on the same system, the speech cannot have different QoS values per
protocol. i.e. If an SV9100 is programmed to use NetLink and SIP trunks, the speech will use the same
RTP/RTCP QoS value whether a NetLink call is in progress or a SIP trunk call is in progress. The
signalling for both protocols, however, can have different values.

IP Address Collision

IP Address Collision
Description
The system sends Gratuitous ARP (G-ARP) requests to check whether any other devices in the network
have the same IP address as either the GCD-CP10, the GPZ-IPLE or the GPZ-IPLE Gateway IP addresses.
If an IP address collision is detected an alarm can be triggered.
SV9100 Programming
The only programming required is for the Alarm setup, the Alarm Display Telephone and any email
notification if required.
Set up the parameters of the Alarm using Alarm number 57 in Easy Edit – Advanced Items/Maintenance/
Alarms/System Alarm Setup (PRG90-10).
Assign the extension number for the Alarm Display Telephone in Easy Edit – Advanced Items/
Maintenance/Alarms/System Alarm Display Setup (PRG90-50-01).
SV9100 Requirements
The following information provides requirements for the IP address collision detection.
Hardware
The SV9100 requires the following hardware:
GCD-CP10
GPZ-IPLE
The Alarm can be displayed on the following terminal types:
DT300
DT400
DT700
DT800
Capacity
Up to 3 IP addresses can be checked for duplication using this feature. The 3 IP addresses are the GCD-
CP10, the GPZ-IPLE and GPZ-IPLE Gateway address.
Operation
