Yes.  As well as letting ifconfig.le1 do it for me...

Same thing as le0 (except "le1" for each "le0", the IP that I
specified for le1 instead of le0's IP, etc.  see below)

Probe claims:
le1 at sbus0 slot 1 offset 0xc00000 level 7 address .....
(8 rx buf, 2 tx buf)

I have notes that claim this is what the 501-1881 version uses.
OTOH, the -1450 uses 1-8 off for AUI.  Note that the notes that describe the
1881 settings (what you have mentioned) imply that 7-8 control the
availability
of +12V to the AUI connector.  Since I can see power on the transceiver's
*power* LED... (can verify with a VOM if need be...)

ifconfig -a
shows the interface as "up" (same flags as le0 -- 8863), lists the MAC
address (same as le0) along with the IP I assigned.  Media type is 10base5
instead of
"autoselect" (for le0).  IPv6 address the same except "%le1" appended
instead of
"%le0".  Status claims "no carrier" instead of "active"...

I note SBE and FSBE (-1860 and -2015) are explicitly mentioned -- but not
"SEC"
(1.5.2R).  It is questionable whether the SEC supports a media type
option -- since
the DIP switch seems to imply this is manually configured.  Note that the
interface
doesn't "automatically attempt to switch to the other media" despite the
fact
that no carrier is found.

"10Base2" is not accepted as an option to ifconfig when I attempt to do
this manually -- regardless of what position the DIP switches are in!

Removed the transceiver from le0 (same machine!) and installed on le1.
After verifying that it DIDN'T work, replaced it on le0 and verified that
the transceiver hadn't"coincidentally" died the instant I unplugged it from
le0...

(sigh)  I'll just pull the card and use some other box as my routers...
(need 10Base2 on one I/F and 10BaseT -- the le0 interface! -- on
the other).  If I get a chance, I'll throw this in a Solaris box and
see if it works there...

Anyone have a (known working) pair of these they would like to part with???

Thanks!
