1 Run recurring discovery
1.1 Check the discovery options
Telnet/SSH and SNMP (if only Telnet, then, select “Telnet and SNMP”)
Discovery options (recommended options, user can change) *Discovery depths: 2
*Scan destination subnets *Scan all connected subnets *Minimum mask: 22
*Use CDP to Discover Neighbor Devices *Find Routing Protocol Neighbor via SNMP *Use CLI Routing Table to discover Next-hops
*Retrieve inventory information of device/module/interface
Note: If you don’t want to discover a certain device type, for example End System or IP Phone, you can check these device types in the Do-Not-Scan window.
1.2 Click the “Start Discovery” button to start the job manually, or you can schedule the rediscovery task to run on your scheduled time by choosing Workspace > Schedule from the top navigation menu.
Note: You need to keep the admin WS client running to start the scheduled discovery.
1.3 After the discovery is finished, choose the Export Results option in the Live Network
Discovery window right click menu to export to your PC. This is an optional step to view
the logs which include all scanned IPs NetBrain can ping/snmp/telnet/ssh successfully or not.
2 Fine tune workspace
Navigate to the Workspace menu, and click on Manager to open the Workspace Manager window
2.1 Review unknown IPs:
2.2 Remove decommissioned devices:
First verify those devices cannot be discovered, then remove them from the workspace. - In the Workspace Manager window, choose Missed Devices and then select all
entries. Right-click on the selected entries and then choose Discover Selected
Device(s).
- In the Live Network Discovery window, choose Scan IP Range with the options below:
- After the discovery is completed, reopen the Missed Devices report. Remove the devices that have not been discovered for certain period of time (e.g. 7 days) by sorting on the “Last Modified Time” field, then select Remove Selected Devices
From Workspace.
2.3 Rediscover SNMP-only devices:
- Navigate to the Workspace menu and click on Manager. In the Workspace Manager window, choose Discovered by SNMP, and then select all entries at the right. - Right-click on the selected entries and then choose Discover Selected Device(s).
- Discover using Scan IP Range with same options as in step 2.2.
- After discovery, reopen the Discovered by SNMP table, check all IPs/devices to allow NetBrain NS server snmp access by updating FW rules or ACLs.
2.4 Update unknown SNMP OID devices:
In the Workspace Manager window, choose Unknown SNMP sysObjectID to view all devices/IPs with OIDs that are not in the NetBrain supported vendor/model table.
- Right click on one entry and choose Send to NetBrain, so NetBrain will update the supported vendor/model list to include this OID.
- Rediscover the device from the Unclassified Network Devices list. Right click on the entry and choose Discover Selected IPs.
2.5 Review and cleanup duplicate IPs:
Order section, modify the management interface selection order as you desire (e.g. Loopback100;loopback;vlan;g;f). Click the Apply button. (It may take a few minutes.)
3.2 Export asset report and customized report:
Navigate to the Home menu, and click on Asset Report. In the Asset Report window, choose Create Asset Report. In the Asset Report window, right click on Entire
Network-Site and then choose Export Customized Report…
3.3 Find all new devices (optional):
Open the device report.csv file, and sort on the findtime field to find the latest
discovered devices during the scheduled auto discovery. See sample screenshot below:
4 Update hostname changed devices and login credentials
4.2 In the Tune Shared Network Settings window, sort the Hostname column, multi-select (using Shift/Ctrl keys in keyboard) the hostname changed entries whose value in the hostname field is not “Unchanged”, right click and select Discover Selected IP to launch the Live Network Discovery window in step #4.4.
4.5 Switch back to Tune Shared Network Settings window, sort by the Telnet, Login, Enable, and SNMP columns to see which devices failed on that type of access (CLI/snmp), and export the whole table to a spreadsheet by right clicking on the table and choose Export
Results. You can also analyze the table to update FW rules, ACLs, new credentials
(login/password/snmp_string) and make sure NetBrain has full access from NS server to all network devices via CLI/snmp.
5 Server benchmark and local CLI
5.1 Setup server benchmark:
This is to enable NetBrain server to auto backup live network data.
- Navigate to the Workspace menu and click on Benchmark > Server Benchmark to launch the WSS (workspace server) web page. Set the benchmark schedule to daily, weekly, or monthly based on your needs. Check all options for live data, and click
Submit.
- Click the DataFolder tab to check the size of benchmark data
- Click Data Storage Settings to define how many days of data to keep. Suggestion: 30~90 days for DataFolder, 7~15 days for One-IP Table.
5.2 Setup local CLI access:
This is to setup your own Tacacs account login credentials to telnet/ssh to live network devices from your own workstation or Jumpbox.
- Navigate to the Workspace menu and click on Settings in the Local Network Settings section. Add you Tacacs account username/password.
