.::: How To Commission & Enable SNMP an OmniSwitch Alcatel Lucent for NMS :::.

Before you begin. See the appropriate OmniSwitch documentation for more information about the CLI command syntax and SNMP.

Note: The NMS cannot discover an OmniSwitch that is configured with the factory default settings.

1. Open a console window using a direct console port connection to the OmniSwitch.

2. Create a Loopback0 interface and assign an IP address to the interface by entering

the following:

ip interface Loopback0 address xxx.xxx.xxx.xxx

where

xxx.xxx.xxx.xxx is the IP address of the interface
