Second ethernet have the same ethernet addr !!!

2007-12-25 7:23:00

Thank's a lot for all who respond, and especially to

vellani@aplexus.jhuapl.edu (Thomas Vellani) for the ie* question

Ethernet specifications says that one host must have only one

ethernet address. It's compulsory with XNS.

Of course, the ethernet address may be changed by ifconfig if

the two interfaces are on the same wire, or if there is a bridge.

But in this case, what address should be used, to assert the

unicity of ethernet addresses.

For the ie* names, here is what SUN assumes

ie0 CPU board

ie1 MULTIBUS ethernet

ie2 first SCSI ethernet

ie3 second " "

I'd better set the switch to be the first ethernet rather than the

second. In this case, my second ethernet will be at ie2.

If you want your second ethernet to be at ie1, then modifies

the following line of the config file

# all lines to be local, i.e., carrier supplied by software

device ie0 at obio ? csr 0xf6000000 priority 3

device ie1 at vme24d16 ? csr 0xe88000 priority 3 vector ieintr 0x75

device ie2 at vme24d32 ? csr 0x31ff02 priority 3 vector ieintr 0x76

device ie3 at vme24d32 ? csr 0x35ff02 priority 3 vector ieintr 0x77

device ie4 at vme24d32 ? csr 0x2dff02 priority 3 vector ieintr 0x7c

Thank's again.
