xen discuss - Sep 2008 - snv build 98 - hangs after logical interface creation

All,

Laptop (tecra M5) with nevada build 98.

When Solaris comes up I have DHCP on the e1000g0 interface.

I then plumb up a logical interface (e1000g0:1)
ifconfig e1000g0 addif 10.10.10.1/24 up
route add default 10.10.10.254

I find that networking through my primary (DHCP) becomes flaky at best, 
or stops responding.
(ifconfig -a, still shows the primary interface as having the dhcp 
provided IP, but network
access hangs.

Suggestions to how I should trace this issue further.

thank you
regards
sundeep

I have a simular situation.

I have a static IP on e1000g0, and I plumb e1000g0:1 with
a DHCP address.

Large ftp''s hang, and I have to reboot.

Also build 98 on a Tecra M5

Is it related to xVM kernel?
There was a problem with some e1000g drivers some time ago...

Hi Bob,

did that for the 1st interface
ifconfig e1000g0 addif 10.10.10.1/24 mtu 1400 up

Things seem to be working for now.  ie no hangup in the last 5 mins.

BTW: the purpose is to setup a zone on ip 10.10.10.201

Can you suggest the zonecfg sequence to change / add to the current 
params to change the default from 1500 to say 1400

regards

I''m hitting similar problems, e1000g driver has been somewhat flaky
recently. Try workaround here:

http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6727837
6727837 e1000g doesn''t work with LSO enabled

Works for me.
