- Hi there,
-
- I have a question regarding two NC400 in a SPARCserver 4/690 (Solaris 1.0.1 or
- SunOS 4.1.2).
-
- Is it possible to configure the two NC400 and the Sun, if both NC400
- ethernet boards are accessing the same physical wire (10Base2)?
-
- As I know, both boards will have the same ethernet MAC address (downloaded by
- software, not fron an EPROM), but will have different hostnames or IP
- addresses. I assume that this will produce some arp/rarp conflicts because
- two IP addresses will have the same ethernet MAC address.
-
- The installation guide to the NC400 only shows a multihomed server with an
- ethernet segment per NC400 board.
-
- Our ethernet is not designed to split it up into segments (in fact it's
- poorly designed but don't flame me...) :-(
- There is just one way we could use two segments, but there is a little
- problem. At the moment this two segments are bridged. Some PC's are
- accessing an IBM AS/400 over LU6.2 encapsulated into raw ethernet frames
- through this bridge. In addition there is some EtherTalk and IBX/SPX traffic
- through the bridge.
-
- If I would replace this bridge by the Sun (including the two NC400), would
- this connections (EtherTalk, encapsulated LU6.2, IPX/SPX) still work over
- this Sun? I assume no, since there would have to be some bridging
- capabilities between the NC400's...
-
- Who could me tell more?
- Has anybody some installation hints for us?
-
- Thanks for any hints in advance...
-
- Daniel
