C–VirtualNIC Interface Configuration and Administration VirtualNIC Interface Configuration and Administration Failover to a port on a different Ethernet gateway In this example, if the Ethernet port associated with iocguid 0x66a02de000048 (i.e., Ethernet port 2 on gateway 48) fails, then traffic going over eioc1 will begin using Ethernet port 2 on gateway 03c. This type of failover allows traffic to continue even if the entire gateway card fails or is rebooted. This type of failure requires a second gateway card to be in the fabric. NOTE: In this example the same adapter port is being used for both the primary and the secondary connection. {CREATE; NAME="eioc1"; PRIMARY={ DGID=fe8000000000000000066a21de000048; IOCGUID=00066a02de000048; INSTANCE=0; PORT=1; } SECONDARY={ DGID=fe8000000000000000066a21de00003c; IOCGUID=00066a02de00003c; INSTANCE=0; PORT=1; } } Combination method In this example, if either the Ethernet port, the Ethernet gateway or the adapter port fails, traffic using eioc1 will begin using Ethernet port 2 on gateway 03c via adapter port 1. {CREATE; NAME="eioc1"; PRIMARY={ DGID=fe8000000000000000066a21de000048; IOCGUID=00066a02de000048; INSTANCE=0; PORT=2; } SECONDARY={ DGID=fe8000000000000000066a21de00003c; IOCGUID=00066a02de00003c; INSTANCE=0; PORT=1; } } Creating VirtualNIC Ethernet Interface Configuration Files For each Ethernet interface defined in the /etc/infiniband/qlgc_vnic.cfg file, create an interface configuration file: For SuSE and SLES OS: /etc/sysconfig/network/ifcfg-NAME For RHEL OS: /etc/sysconfig/network-scripts/ifcfg-NAME where NAME is the value of the NAME field specified in the CREATE block.

C–VirtualNIC Interface Configuration and Administration VirtualNIC Interface Configuration and Administration Example of ifcfg-eiocx setup for RedHat systems: DEVICE=eioc1 BOOTPROTO=static IPADDR=172.26.48.132 BROADCAST=172.26.63.130 NETMASK=255.255.240.0 NETWORK=172.26.48.0 ONBOOT=yes TYPE=Ethernet Example of ifcfg-eiocx setup for SuSE and SLES systems: BOOTPROTO='static' IPADDR='172.26.48.130' BROADCAST='172.26.63.255' NETMASK='255.255.240.0' NETWORK='172.26.48.0' STARTMODE='hotplug' TYPE='Ethernet' After modifying the /etc/infiniband/qlgc_vnic.cfg file, restart the VirtualNIC driver with the following: /etc/init.d/qlgc_vnic restart VirtualNIC Multicast The primary goal of VNIC Multicast is to reduce the replication of multicast packet transmission from the EVIC to InfiniBand hosts. Figure C-1 demonstrates the transmission of multicast traffic without using IB_MULTICAST: D000046-005 B C-9
