This section addresses the files that affect the configuration of isis software. Some of these are isis specific files, while others are operating system files.

The isis sites file is located in $NMS_HOME/etc/run_isis. It identifies the node on the network that will be running isis, typically the site ID = 001 and the host IP using 127.0.0.1 (localhost), and defines the TCP/IP port numbers under which it will run.

The standard isis sites file should always specify the standard ports you see in the example below. If you wish to override the standard isis ports set the ISISPORT environment variable accordingly (see notes below on ISISPORT). The nms-isis start script will examine the ISISPORT environment variable and - if set to anything other than 2042 - will create an alternate sites file (sites.$ISISPORT) with the proper port configuration.

The format of this file specifies the isis node number, network service ports, hostname (or IP address) along with an optional user name and comment. Below is a typical sites file for a single node where isis traffic is restricted to the loopback address.

The leading plus sign is very important and this file cannot have any comments (except in the comment section of the end of each line). If the isis sites file does not exist, the nms‑isis startup script will create it, which is the recommended way to manage the sites file.

The isis.rc file is located in $NMS_HOME/etc/run_isis. It contains the following information:

A generic isis.rc license file is included in the Oracle Utilities Network Management Systems software distribution.
