Procedures 3To set up a network connection to an HA-enabled switch and other CMS

•Edit the /etc/defaultrouter file.
Editing the
/etc/hosts File 3
1. To save a backup copy of the file, enter:
cp /etc/hosts /etc/hosts.old
2. To edit the /etc/hosts file, enter:
vi /etc/hosts
3. Add a new line in this file for each ACD/switch that will connect to
this computer using TCP/IP. Lines must also be added for any NTS
devices installed on the system.
This example shows the recommended default IP addressing
scheme for the two ethernet ports installed on the server. The
hostname “cms_1” represents the second network interface, which
is on the same private subnet carrying the link to the switches. This
example also shows the first ethernet port conncecting to two NTS
servers (cmsterm1 and cmsterm2).
4. Press the Esc key to leave the edit mode.
5. Enter :wq to save and quit the existing file.
6. To edit the hostname files associated with the second network
hostname created in /etc/hosts, enter one of the following:
