NetBrain Workstation Live Network Access Guide
How NetBrain Accesses the Live Network
Summary
Many NetBrain functions such as live network discovery, benchmarking, path discovery and monitoring require access to the live network. In order for these functions to work, you need to input live network settings into the NetBrain system which include: 

Username/password pairs and privilege passwords. These credentials are used to Telnet/SSH to devices and retrieve live data via CLI show commands. SNMP RO strings are used to access devices via SNMP. Monitoring devices also requires SNMP RO strings. These settings are stored in the server database and the passwords are encrypted. The administrator can also control whether a user is able to use these settings. NetBrain will use the credentials to retrieve data from the live network via SNMP polling and CLI show commands. NetBrain will NEVER make any configuration changes in the live network. Live Network Discovery
Based on user selection during discovery, NetBrain uses the following methods to access the live network: 


Ping SNMP Read‐only Telnet/SSH For the quickest and most comprehensive discovery, make sure that the NetBrain server can access the live network with ALL methods listed above. NetBrain uses a special neighbor‐walking algorithm to discover the network. It only uses one Telnet/SSH session per device. Expect light network traffic during NetBrain discovery. The actions that the NetBrain discovery engine uses are: 1. Ping 2. SNMP RO GET to a few OIDs 3. Telnet to port 23 or SSH to port 22, and issue the following commands (based on user selection) a.

Show run Show ip route summary Show ip route Show cdp neighbor Benchmarking While benchmarking, the NetBrain server Telnet/SSHs to the device and issues CLI show commands to retrieve configuration files, route tables, ARP tables, CDP tables, MAC tables and interface information for all devices in the system. You can also define your own CLI show commands. For Cisco IOS devices, the benchmarking process may issue the following show commands: NetBrain Workstation

Since benchmarked data is a snapshot of your network at a specific point in time, it can also be used for comparison purposes, such as to recall a good network state while you troubleshoot a problem. When you implement a network change, we recommend that you run a benchmark before and after implementation and compare the two sets of data to find differences, so you can find any issues caused by your changes, such as missing routes. Path Discovery
Starting from two end points, you can discover and map an application path. Depending on the method used to discover the path, the system will retrieve routing via SNMP or CLI from the live network. If the system retrieves routing via SNMP, it will only retrieve routing related to the destination rather than the entire routing table. Otherwise the system retrieves routing tables from the device via show commands such as “show ip route”. You can also select the Via Cached Route Table option to find the historical path based on historical routing tables. Monitoring
Monitoring functions use SNMP polling to retrieve performance data from the live network such as CPU, memory, interface delay, and bandwidth usage. IP Accounting, IP SLA and NetFlow
By launching IP accounting, IP SLA and NetFlow functions, the system Telnet/SSHs to the device and issues the corresponding show commands to retrieve the data. NetBrain does not configure IP Accounting, IP SLA or NetFlow for you. It’s not a NetFlow Analyzer server either. Show commands
If show commands can be issued from a non‐privileged mode, then the system does not go to privileged mode. Otherwise the system must go to the privileged mode and issue show commands. NetBrain does not make any network configuration changes. NetBrain Workstation
