CESID AUTO UPDATES, UNSUPPORTED CONFIGURATIONS
Automatic updating of CESID when a phone moves to a new location will
not
work under the
following circumstances:
•
If the IP phone is connected to an Ethernet hub
•
If the IP phone is connected to an L2 switch that does not have CDP or STP/RSTP enabled
•
If multiple IP phones report connectivity to the same L2 port. The system will detect this
condition upon device registration.
The following examples of network configuration should
not
be used in an installation that
requires E911 services:
•
Some L2 switches use CDP and others use STP/RSTP (see Figure 14 below). The problem
with this network configuration is that the 3300 ICP could receive information from
STP/RSTP that conflicts with information received from CDP. Since the ICP is not receiving
data for all ports from both protocols, conflicts cannot be resolved.
•
Some or all L2 switches have both CDP and STP/RSTP disabled (see Figure 15 on
page 135) or sets are connected to an L2 switch via a hub (see Figure 16 on page 135).
From the perspective of the 3300 ICP, it will appear that several devices are all plugged
into the same L2 port (i.e. the port of the L2 switch that is one step higher in the network
tree). For E911 to function correctly, an IP phone should be associated with only one L2
port MAC address.
