Chapter 11: Discovering your network
This section provides detailed instructions on how to use the Avaya Network Management Console IP
Discovery feature.
You can use the IP Discovery feature to discover all the supported nodes on your network. The system
displays a list of subnets or an empty list when you run the IP Discovery for the first time.
There are two ways you can specify subnets to discover after selecting Add from the Edit menu or clicking
the Add button on the toolbar:
• You can specify the Subnet IP address and the subnet mask.
• You can specify the Subnet IP address and a router interface which serves as the router for the given
subnet. Upon discovery, the router is contacted and the subnet mask is determined using the
standard interface SNMP query.
From Network Management Release 5.2 service pack 3 there is a new menu option in the Actions menu
called Discover Interfaces and it is not selected by default.
When you select this option, you can query all SNMP-enabled devices for their IP interfaces and display
them in the device list of Network Management Console. Also, the IP information of the directly connected
subnets is automatically added to the subnet list of the discovery window, however they won't be checked
for discovery by default.
If you do not select this option, you can discover only the primary management interface (PMI) of the
supported device.
The discovery process sequence consists of the following steps:
1. IP Discovery
2. VoIP System View Discovery
3. IP Phone Data Discovery
4. Port Connection Discovery
Note:
From Network Management Release 5.2 service pack 3, Network Management Console does not use
ICMP Echo messages (ping packets) for discovery. Discovery process is exclusively based on the
SNMP protocol instead.
Note:
All toolbar buttons and menu items referred to in this section are in the Discovery window.
