On my R410's I have ethernet adapters that have twin MAC addresses: one for the regular use and the other for a Baseboard Management Controller (IPMI) that can be used to reboot hung machines etc.
All my normal eth cards are assigned to a 10.0.x.x network by DHCP. So far so good. Now if I try to set the second IP address to something in the 10.0.x.x range then things work. Say 10.0.5.3. I can ping the same physical server (and the same physical card) on twin IP addresses from any remote machine. arp from the remote pinging machine shows: Address HWaddress Flags Mask Iface 10.0.0.3 00:26:B9:58:E6:46 C eth0 10.0.4.3 00:26:B9:58:E6:48 C eth0 10.0.0.3 is the normal ethernet IP assigned via DHCP and 10.0.4.3 is for the BMC. But let's say I wanted the BMC to respond on the 172.16.x.x subnet. I can set this address fine. Say, 172.16.0.3 But if I try to ping 172.16.0.3 then there is no response. Surprisingly, arp still shows both addresses but the remote ping does not work. Address HWaddress Flags Mask Iface 10.0.0.3 00:26:B9:58:E6:46 C eth0 172.16.0.3 00:26:B9:58:E6:48 C eth0 Do I have to do something else to make this work? How do I have two subnets on the same adapter? Commands I used: ipmitool lan set 1 ipsrc static ipmitool lan set 1 ipaddr 172.16.0.3 ipmitool lan set 1 netmask 255.255.0.0 -- Rahul _______________________________________________ Linux-PowerEdge mailing list Linux-PowerEdge@dell.com https://lists.us.dell.com/mailman/listinfo/linux-poweredge Please read the FAQ at http://lists.us.dell.com/faq
