Sample /etc/hosts File Entries for a Single Network Configuration
This section describes entries that you would add to the /etc/hosts file if
your configuration was identical to the configuration examples listed
earlier in this section.
#
# Internet host table
#
192.168.126.1 voipbox1 voipbox1a voipbox1b voipbox1c voipbox1d
192.168.126.2 voipbox2 voipbox2a voipbox2b voipbox2c voipbox2d
192.168.126.3 active activea activeb activec actived
192.168.126.4 standby standbya standbyb standbyc standbyd
CAUTION: The host names that end in a, b, c, and d are used internally
by Intelligent Mirroring or Call Builder (or both). These names must be
present in the /etc/hosts file.
Dual Network
Configuration
To configure the Primary and Secondary servers so that they are each
connected to two networks, follow the instructions in this section.
Dual network configuration is possible only if the UMS software is
running on different servers than the Call Processor software. If you are
running all VCX software on a single pair of servers, you cannot configure
UMS for dual networks.
3Com recommends that you configure the systems on which Intelligent
Mirroring runs so that each one is connected to two independent
networks on separate switches. This provides additional reliability should
problems develop on either network (for example, if a switch fails).
The examples in this section are based on the assumption that two
subnetworks (192.168.126.XXX and 192.168.127.XXX) are used. If you
choose not to use subnetworks, modify the examples accordingly.
