Pingsweep

 

Advanced discovery can use either pingsweep or autodiscovery by ARP and CDP cache tables.

The parameter file for pingsweep allows the user to specify IP ranges and alternative SNMP community strings in case connectivity fails when using the default community string.

# seed range for ping scan with default community

Note that the login and password entries are used to populate the resulting router profile for use with CLI collection, and are not used during the pingsweep/VLAN discovery step.

This method would run a ping sweep through the IP addresses in the above ranges. For the IP addresses which are reachable via ping, the SNMP information would be collected and parsed into an intermediates directory, which can later be imported during config extraction through the File > Create Network > From Collected Data wizard, Files tab, VLAN Discovery directory. If the pingsweep parameter is not used, SNMP will be used instead to test reachability to the devices.

A router profile would also be created as a result of this ping sweep with the devices that were reachable, for further use to collect CLI data via the Scheduling Live Network Collection task. For this reason, the login, password, and enable (privilege) password can be specified for given ranges to automatically populate the login and password of the resulting router profile. The passwords are provided in encrypted format, using the same format as the passwords in the router profiles saved in the /u/wandl/data/.TaskManager/profile/.
