Troubleshooting
Problem
This technote contains information on how to determine the type of Ethernet network interface that is used on your machine and how to change the default setting in the ibmlb.conf file.
Resolving The Problem
By default, Dispatcher is configured to load balance traffic on 100 Mbps Ethernet network interface cards.
To change the default setting, you must edit the /opt/ibm/edge/lb/servers/ibmlb.conf file.
The default 100 Mbps Ethernet adapter is specified in ibmlb.conf as eri.
- To use a 10 Mbps Ethernet adapter, replace eri with le.
- To use a 1 Gbps Ethernet adapter, replace eri with ge.
- To use a multi-port adapter, replace eri with qfe.
- To support multiple types of adapters, replicate the line in the ibmlb.conf file and modify each line to match your device type.
For example, if you plan to use two 100 Mbps Ethernet adapters, the ibmlb.conf file must have a single line that specifies the eri device.
If you plan to use one 10 Mbps Ethernet adapter and one 100 Mbps Ethernet adapter, you must have two lines in the ibmlb.conf file. One line specifies the le device and one line specifies the eri device.
To determine the type of Ethernet network interface in use on your machine, issue the following command from the Solaris command prompt:
ifconfig -a
If the following output results:
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1 inet 127.0.0.1 netmask ff000000
eri0:
flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2 inet 9.42.93.208 netmask fffffc00 broadcast 9.42.95.255 ether 0:3:ba:2d:24:45
Edit the ibmlb.conf file as follows:
eri -1 0 ibmlb
