You can modify the attributes ENA uses to manage a device.
You may want to modify these attributes, for example, when:
- setting CLI access.
- the read community string on a device has changed.
- a device is successfully polled only intermittently.
- a managed device has been replaced and the new device has inherited the old IP address.
- an incorrect device type is associated with a device, e.g. VM platforms running SNMP may be incorrectly identified as managed hosts.
To modify attributes ENA uses to manage a device:
- In the Main Menu, click Administration.
- Click Device Inventory.
- Select the device you want to modify and click Modify at the bottom of the browser. This will open the Modify Devices window.
- Specify the default level of device management in the Management Level field, either 'Full', 'Full (No Ports)', 'Basic', 'Ping Only', 'Full (Virtualization)' or 'None'. The default is 'Full'.
- Specify the particular device type in the Device Type field, or leave to the default 'Auto' for Auto Discovery to determine the type.
- Enter the device name (which must be resolvable on the Entuity server) or IP address Entuity uses to poll the device in the Polled Name/IP address field.
- Specify the zone in which the managed device is located in the Zone field.
- Specify the device name displayed within the product in the Display Name field, either 'Polled Name / IP address', 'Resolved Name', 'Resolved Name (fully qualified)', 'IP Address', 'Custom' or 'System Name'. The default is 'Polled Name / IP address'.
- Specify the IP version of the device in the IP Protocol radio buttons, either IPv4 or IPv6.
- Tick the Allow Duplicate IP Addresses box if you want to permit the addition of a device with the same IP address as one already managed.
- Specify the SNMP version enabled on the device in the Version field, either v1, v2c or v3.
- Tick the Use SNMP Bulk Get box if you want to receive back multiple varbinds back for each request. Leave the box unticked if you want to receive back the normal 1 varbind back.
- Enter the SNMP read community string in the Read Community field, by default 'Public'.
- Specify on which port the device's SNMP agent receives its requests, in the SNMP Port (UDP) field. By default, this is set to the default UDP port 161.
- Specify the SNMP timeout in seconds in the Timeout (seconds) field.
- Specify the number of SNMP retries in the Retry field.
- Specify the maximum SNMP packet size Entuity uses when polling devices in the Max Packet Size (bytes) field.
- Once you have made your changes, click OK to save, otherwise click Cancel.
