SNMP scanning allows you to discover all SNMP capable devices on your network and import them into SysAid. When creating an asset from an SNMP scan, SysAid uses the MAC address of the first network interface detected on the device as the asset ID.
To perform an SNMP scan, fill out the fields as follows:
- Discovery service name
- When discovering SNMP devices on the same LAN as the SysAid Server, you can scan directly from the SysAid Server. However, if you need to scan another network, or if there are firewalls segmenting your internal network, the SysAid Server might not have access to all of your network devices. In this case, you may install the Remote Discovery Service on the network you would like to scan. Select the name of the desired Remote Discovery Service you would like to use for the network discovery scan. Click here to read more about the Remote Discovery Service.
- IP Range
- This is the IP range you would like to scan. Enter the starting IP address in the first box and the ending IP address in the second box. The range is inclusive, meaning the IP addresses in both the starting and ending boxes will be scanned.
- SNMP Version
- Choose the version of SNMP you would like to use when scanning your network. If a device does not support the chosen SNMP version, it may not be discovered during the scan.
- Community String
- This is the username for logging into the SNMP device. The default for most SNMP devices is "public."
- Community Password
- This is the password for the username entered under Community String. Versions 1 and 2 of SNMP do not require passwords, and in those cases this field can be left blank.
- Exclude IP List
- This field allows you to enter a list of IP addresses within the chosen range that you would like to exclude from the discovery scan. Individual IP addresses are separated by commas.
- Check this box if you would like the entered network scan to be run on a regular basis. For example, a scan could be scheduled weekly to ensure that any new devices added to your netword are detected by SysAid, and to detect changes to any of the already discovered devices.
- Next run on
- If you've scheduled your network scan, enter a date and time here. The scan will always run at the time of day entered here, and the Repeat every field will be based upon the date entered here.
- Repeat every
- If you've scheduled your network scan, enter the frequency of the scan. The Repeat every field is based upon the initial date entered in the Next run on field. For example, if the first scan is scheduled for a Monday at 11:00 AM and you choose to repeat every 1 week, the scan will run every week on Monday at 11:00 AM.
- If this box is checked, SysAid prepares a list of "live" IP addresses within your chosen IP range and scans these only. If this box is not checked, SysAid scans every single IP address in the chosen range. A quick scan is faster, but can miss any devices that go "live" after the list of IP addresses is prepared.
- Add/Delete/Run now
- After entering the details of a new scan, click Add to add that scan. Note that this will not run the scan-- you must still click Run now to run the scan. Click Delete next to an existing scan to delete that scan. Click Run now next to an existing scan to run that scan. For non-scheduled scans, clicking Run now is the only way to run them.
- Refresh remote discovery service
- At the bottom of this page you can see the Refresh Remote Discovery button. By clicking this button you can clear all the Discovery service names that do not have a scheduled scan from the list. The list will be repopulated any time a Remote Discovery Service you've installed contacts the SysAid Server. The Remote Discovery Service contacts the SysAid Server any time the SysAid Discovery Service service is started/restarted.
