Hi Gilad,
Since I cannot reproduce this Bcast address 0.0.0.0 during statelite
provision, I think it is not directly caused by xCAT statelite provision.
Could you provide more information about this? So that we can do more
investigation.
Could you give us node definition and ifcfg-eth0 file contents?
Best Regards

Yuan Bai,
1, Is eth0 your install nic? install nic is configured by dhcp in xCAT, if
eth0 is install nic, the bcast is not configured by xCAT directly, it
should be calculated.
[gb] Eth0 is the install NIC. On other NICs configured by DHCP (in
statefull install for example) I see the right bcast address.
Usually the bcast address is being configured automatically.
2, Is eth0 configured by scripts from xCAT? for example, do you use
confignics or confignetwork scipts or etc to configure eth0?
If you using scripts in xCAT, could you tell me which scripts? I can look
into it.
[gb] No scripts are used, anyway after boot there is not much can be done
to this NIC because no
3, If you using other scripts to configure eth0, the following command may
cause the bcast address as 0.0.0.0:
/sbin/ip link set eth0 down
/sbin/ip addr add 10.10.101.51/24 dev eth0
/sbin/ip link set eth0 up
You should use:
/sbin/ip addr add 10.10.101.51/24 broadcast
10.10.101.255 dev eth0
[gb] There is no issue with configuring the address manually after boot
(ifconfig or ip), so we have a simple workaround. The reason I am trying to
find the root course is because there might be some hidden issue that will
hurt something else later. I am basically trying to understand why the
bcast address is not being calculated and configured at boot time.
The only time this NIC is being configured is the boot time, after that, it
is impossible to bring it down.
Any idea why in the first place there is no bcast? Any DHCP options that
prevents it?
THX a lot!!!

Sorry for mistake of eth1, should eth0 in previous mail.
/sbin/ip addr add 10.10.101.51/24 dev eth0
/sbin/ip link set eth0 up
You should use:
/sbin/ip addr add 10.10.101.51/24 broadcast
10.10.101.255 dev eth0

Hi Gilad,
I provisioned sles12.2 statelite using xCAT, I cannot reproduce this Bcase
adress 0.0.0.0 for install nic through provisioning.
I have following questions:
1, Is eth0 your install nic? install nic is configured by dhcp in xCAT, if
eth0 is install nic, the bcast is not configured by xCAT directly, it
should be calculated.
2, Is eth0 configured by scripts from xCAT? for example, do you use
confignics or confignetwork scipts or etc to configure eth0?
If you using scripts in xCAT, could you tell me which scripts? I can look
into it.
3, If you using other scripts to configure eth0, the following command may
cause the bcast address as 0.0.0.0:
/sbin/ip link set eth0 down
/sbin/ip addr add 10.10.101.51/24 dev eth0
/sbin/ip link set eth0 up
You should use:
/sbin/ip addr add 10.10.101.51/24 broadcast
10.10.101.255 dev eth0

Subject: [xcat-user] Bcast address 0.0.0.0 Statelite deployment
All,
I am assuming many linux experts on this list, so since I am not sure this
is purely xCAT issue, any hints are more than welcome 😊
In our statelite deployment the boot interface comes up with broadcast
address of 0.0.0.0 –
# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 6C:AE:8B:08:8E:03
inet addr:10.10.101.51 Bcast:0.0.0.0 Mask:255.255.255.0
….
The broadcast address can be setup easily with ifconfig eth0 broadcast.
Eth1 boots with the right bcast address.
I wonder what could cause this issue, when seems there is no limitation on
setting it.
OS is SLES12.2 and deployment method is statelite (statefull works as
expected).
THX in advance!
