	I am not well with settings. But there are EPICS_CAS_***
settings for server/IOC. If I am not mistaken server/IOC will use
EPICS_CA_*** if EPICS_CAS_*** are undefined.

	Another idea comes to me when I read your message. I did some
tests and network is bottleneck of server/IOC CPU performance if
server/IOC algorithms are not complicated. From another side Motorola
CPU5100 has 2 networks. Maybe it will decrease CPU loading?
	Does anybody do that?

Thanks, Andrei.

Subject: CA for IOCs w/ dual NICs

Hi,

There are two network interfaces (N.I.) on my IOC, each attached
to  a  different  IP address. I  thought one could  decide which medm
clients  "Channel Accessing"  which  N.I. by opening two windows.
Both windows  are set with  EPICS_CA_AUTO_ADDR_LIST = NO.
Window #1 is set with EPICS_CA_ADDR_LIST= IP1, while
window #2  is set with  EPICS_CA_ADDR_LIST= IP2.

Is ther any other better way ?   I wanted to make sure  that certain
clients  CA the specified IP, instead of  the other one.  Thus, I
disconnected
one of the cable going to that specified N.I.  However, when I do that,
all the medm clients on both windows  became disconnected from the IOC.

Any pointer highly appreciated,
Kate
