[sles-beta] LWL links from Intel NIC get lost during boot

[Janos.Mattyasovszky at bmw.de]

Hi

10G fibre nic works only (= has a link and enables the laser), when the interface is brought up by ifconfig up...

by installing SLES 12 GA the issue was the same.

I simple execute the command: ifconfig em1 up

Suddenly it works. Currently we have running it with bonding and it
works like it should so I would like to stop with this issue.

slc3:~ # cat /etc/sysconfig/network/ifcfg-bond0
BONDING_MASTER='yes'
BONDING_MODULE_OPTS='mode=802.3ad miimon=100 xmit_hash_policy=layer3+4'
BONDING_SLAVE0='em1'
BONDING_SLAVE1='em2'
BOOTPROTO='static'
BROADCAST=''
ETHTOOL_OPTIONS=''
IPADDR='xx.xx.xx.xx/xx'
MTU=''
NAME=''
NETWORK=''
REMOTE_IPADDR=''
STARTMODE='auto'

We removed the ifcfg- slave files.

My colleague said that he did not change anything at the switch
configuration.
