Hi,
I have an E220R running Solaris 9 with a fiber gig card with the ce driver.
When I hook it to one of our Cisco Catalyst 6500 switches, I get link but
there are a lot of errors on the port. Specifically, FCS-Err and Runts are
incrementing. There are no collisions and no errors of any kind on my
machine, but I experience icky, herky-jerky telnet and gui behavior. Plus
my nightly legato backups, which is what I use this machine for, are hanging
up more than they did when I had it on a cat 5 connection.
Everything points to a duplexing mismatch, except that I don't seem to have
a duplexing mismatch - according to my networking guys the switch can only
do full duplex, while my server says it's set to 1000fdx and the fdx light
on the NIC is on.
My networking guys found doc at Cisco about various switches not
autonegotiating properly with "some" Sun, IBM, and HP gig nics, so we turned
off autoneg on both ends and diddled around with flow control settings for a
day and a half without any improvement, although by turning off flow control
entirely we were able to make it a lot worse.
I would suspect a pinched cable or something like that, but I have the same
problem on another E220R that has a copper-based gig nic, also with the ce
driver, also with a catalyst 6500 switch (but not the same one, which rules
out a busted switch) I never got that resolved.
I have another machine on the same switch, an E3000 with a gigabit fiber
card, that works fine, but this is a little older, not "gigaswift" -- it
uses the ge driver.
So, my questions are
(1) has anyone else had a problem like this, where symptoms point to a
duplexing mismatch but actual settings are correct?
(2) is anyone using the x1141 gigabit card with an E220R - that would be the
older, non-gigaswift one - and if so, does it behave ok with Cisco switches?
Any reason I should avoid buying it to use instead of the X3151?
(3) is anyone successfully using the X3151(fiber) or X3150 (copper) with a
cisco catalyst 6500 switch? Can you send me your driver settings? If you
don't know how to capture them, email me and I'll send instructions.
Thanks in advance for advice - hunches and wild ideas are also welcome, I'm
supposed to get this running within a week! Please email me with anything
and I'll summarize.
thanks,
Mary Dell
