Ping Sweep for Auto-Discovery in Default Tenant

Default Tenant only: You have two choices for Auto-Discovery starting points. Use either or both to best advantage for Nodes configured for the Default Tenant in your network environment:

Discovery Seeds
You designate specific hostnames (not case-sensitive) or IP addresses where Auto-Discovery starts gathering neighbor information.
Ping Sweep
NNMi issues ICMP pings to certain addresses gathered from neighbor information.

Note Ping Sweep works only with IPv4 addresses and only in 16-bit subnets. All nodes discovered using Auto-Discovery are assigned to the Default Tenant.

Ping Sweep sends ICMP ping commands to IP addresses in the ranges defined in your Auto-Discovery rules. Ping Sweep enforces the following limits to the ICMP pings:
- For each specific IP address range, NNMi issues pings across a maximum of the last two octets in the IPv4 address range. This is equivalent to a /16 subnet
- ICMP pings are limited to 500 at one time. This avoids flooding your network or causing spam detection tools to set off an alarm.

Ping Sweep is useful in wide area networks such as ATM, Frame Relay, and Point-to-Point that do not contain an Address Resolution Protocol (ARP) cache.

You configure the Ping Sweep feature at two levels:

"Configure Ping Sweep (override for all Auto-Discovery Rules)"
"IP Address Ranges for the Auto-Discovery Rule" (Ping Sweep configuration for each rule)
