Hi,
I am using ipxe + iscsistart -N/-b options in order to boot on iSCSI
without re-asking the DHCP for my network config (using the iBFT table),
and I found out that when using this options, my network interface does not
have multicast enabled.
Using ipxe + iscsistart -N/-b (iBFT) :
eth0 Link encap:Ethernet HWaddr 00:01:2E:2B:BB:64
inet addr:192.168.1.19 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::201:2eff:fe2b:bb64/64 Scope:Link
UP BROADCAST RUNNING MTU:1500 Metric:1 <=== No MULTICAST here
RX packets:156131 errors:0 dropped:0 overruns:0 frame:0
TX packets:63185 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:190369331 (181.5 MiB) TX bytes:31467961 (30.0 MiB)
Using ipxe + iscsistart -i/-t/-a... (no iBFT) + kernel command line
"ip=dhcp" :
eth0 Link encap:Ethernet HWaddr 00:01:2E:2B:BB:64
inet addr:192.168.1.19 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::201:2eff:fe2b:bb64/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 <=== MULTICAST
Ok
RX packets:150070 errors:0 dropped:0 overruns:0 frame:0
TX packets:54992 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:191218580 (182.3 MiB) TX bytes:13195880 (12.5 MiB)
As you can see, in the second case, Multicast is correctly enabled.
I am not sure where my problem is. Is it ipxe which fails to communicate
some information in the iBFT table to iscsistart ?
Is it iscsistart who does not enable multicast ? Or am I forgetting to do
something and do I have to enable multicast out of iscsistart ?
Any clue is welcome.
Thanks !
