IPSI Priority List
Issue 1.1 June 2005 73
!
Important:
Important: It is important to note that the administration of Local Only, does not affect an
ESS server’s priority but does limit which IPSI list will contain the Local Only
server.
A priority value, entered in the Pri Scr column, is used to distinguish between ESS servers with
the same preference settings, ESS servers with no preference setting, or ESS servers that are
not in the same community as the IPSI.
See Table 2
for a list of ESS servers relative priorities. The ESS server types listed in Tab l e 2
are in order from highest to lowest value.

Table 2: ESS relative priority
Administered ESS server
type
Priority value impact
System Preferred server System Preferred servers will have a higher value than any
other Local Preferred server independent of community or
administered priority value. If multiple System Preferred
servers are administered, the server with the highest
administered priority value will have the top priority on an
IPSI’s list.
Local Preferred servers in
the same community
After the System Preferred preference, the Local Preferred
preference has the second highest value within an IPSI
community. If multiple Local Preferred servers are
administered, the server with the highest administered
priority value will have the top priority on an IPSI’s list.
Local Preferred and Local
Only server in the same
community
An ESS server administered with both the Local Preferred
preference and Local Only will have the value of a Local
Preferred server but can only advertise to IPSIs within its
community.
Local Preferred server
outside its administered
community
The Local Preferred preference has no value outside its
administered community. When outside the administered
community, the value of the Local Preferred server is based
solely on its priority value.
Local Only server A Local Only server only advertises to the IPSI within its
community. The value of a Local Only server is based solely
on its priority value. If a Local Preferred server (outside its
administered community), or an ESS server with no
preference, advertised to an IPSI in the same community as
a Local Only server, the priority score of each server would
determine its ranking on the IPSI’s priority list.
