The Command Line Interface (CLI)
gateway, and thereby eth1:1, uncomment the two lines under the eth0 section of /etc/pump.conf
and comment the two lines under the eth1 section of that file. Save the file and run the /etc/rc.d/
network reload script.
Note: It is recommended that both CMMs use static IP addresses for all interfaces. DHCP addresses may
be unexpectedly lost or changed in some network configurations.
Note: eth0 should always be set to a different subnet than eth1/eth1:1. Failure to set eth0 to a different
subnet than eth1 will cause network errors on the CMM and redundancy will be lost.
8.3.1.1 Setting Static IP Information for eth0
1. Open the /etc/ifcfg-eth0 file using the vi editor. By default, the file contains three variables.
Example:
— BOOTPROTO=“static”
— DEVICE=“eth0”
— STATICIP=“10.90.90.91”
2. Ensure the BOOTPROTO value is set to static.
Note: Linux is case sensitive, so ensure that the BOOTPROTO variable is entered in lower case letters in
the step above.
3. Set the STATICIP variable to the IP address you want to assign to that interface.
4. To set the netmask for eth0, add the NETMASK0 variable and set it to the appropriate netmask
for your network.
5. To set the gateway for eth0, add the GATEWAY0 variable and set it to the appropriate value
for the gateway on your network.
6. To activate the changes, at the user prompt (from the root “/” directory), type:
/etc/rc.d/network reload
8.3.1.2 Setting Static IP Information for eth1 and eth1:1
Note: eth1:1 is static IP address only. It does not support DHCP.
1. Open the /etc/ifcfg-eth1 file using the vi editor. By default the file contains five variables.
Example:
— BOOTPROTO=”static”
— DEVICE=”eth1”
— SETIP=”both”
— STATICIP1=”192.168.100.91”
— STATICIP2=”192.168.100.93”
2. Set the STATICIP1 variable to the IP address you want to assign to eth1.
3. Set the STATICIP2 variable to the IP address you want to assign to the active CMM on the
network. This value should ONLY be set on the active CMM, as it will be synchronized to and
overwritten on the standby CMM.
4. Set the SETIP variable to assign IP addresses eth1 and eth1:1 based on the following table:
