4.3.2.4 EoIB Multicast Configuration
Configuring Multicast for EoIB interfaces is identical to multicast configuration for native Ether-
net interfaces.
EoIB maps Ethernet multicast addresses to InfiniBand MGIDs (Multicast GID). It
ensures that different vHubs use mutually exclusive MGIDs. Thus preventing vNics on
different vHubs from communicating with one another.
4.3.2.5 EoIB and Quality of Service
EoIB enables the use of InfiniBand service levels. The configuration of the SL is performed
through the BridgeX and lets you set dif
ferent data/control service level values per BridgeX®
box.
For further information on the use of non default service levels, please refer to BridgeX docu-
mentation.
4.3.2.6 IP Configuration Based on DHCP
Setting an EoIB interface configuration based on DHCP (v3.1.2 which is available via
www
.isc.org) is performed similarly to the configuration of Ethernet interfaces. When setting the
EoIB configuration files, verify that it includes following lines:
• For RedHat: BOOTPROTO=dhcp
• For SLES: BOOTPROTO='dchp'
If EoIB configuration files are included, ifcfg-eth<n> files will be installed under /etc/
sysconfig/network-scripts/ on a RedHat machine and under /etc/sysconfig/network/ on
a SuSE machine.
DHCP Server
Using a DHCP server with EoIB does not require special configuration. The DHCP server can
run on a server located on the Ethernet side (using any Ethernet hardware) or on a server located
on the InfiniBand side and running EoIB module.
4.3.2.7 Static EoIB Configuration
To configure a static EoIB you can use an EoIB configuration that is not based on DHCP. Static
configuration is similar to a typical Ethernet device configuration. For further information on
how to configure IP addresses, please refer to your Linux distribution documentation.
Ethernet configuration files are located at /etc/sysconfig/network-scripts/ on a RedHat
machine and at /etc/sysconfig/network/ on a SuSE machine.
4.3.2.8 Sub Interfaces (VLAN)
EoIB interfaces do not support creating sub interfaces via the vconfig command, unless working
in
ALL VLAN mode.. To create interfaces with VLAN, refer to Section , “Configuring VLANs”,
on page 66.
