Hi Jeff,
Here are my Sol-8 IOC environment variables:

According to the R3.14 CA Ref Man, section Server Beacons:
If EPICS_CAS_BEACON_ADDR_LIST is not defined,
EPICS_CA_ADDR_LIST is defined, and
EPICS_CAS_INTF_ADDR_LIST is not defined,
then the conents of EPICS_CA_ADDR_LIST will be used to augment the list.
It looks like me setup meets this criteria yet I don't see the server
beason.
Is it because my EPICS_CAS_BEACON_PERIOD is not defined and not defaulting
to the default 15s?
I am running casw but the only time I saw a beacon anomoly whas when I
started
up caSnooper. I'll explicitly set my EPICS_CAS_BEACON_PERIOD but was
wondering
why I get no beacon anomolies.

Kevin,
Your Solaris-8 IOC (acting as a client) probably does not see the server's
beacons because they are addressed to subnet on which your client IOC is not
listening. The EPICS R3.14 CA reference manual explains this situation in
more detail than in past versions of the manual. See the section entitled
"Dynamic Changes in the CA Client Library Search Interval".
It may be that a simple solution will be to expand the server's beacon
address list so that beacons are broadcasted also on your Solaris-8 IOC's
subnet. Alternatively, you could install a CA gateway providing transparent
connectivity for remote clients.
