1. For Grid: From the Grid tab-> GridManager tab -> Discovery service, select Edit -> GridDiscoveryProperties from the Toolbar.
   For members: From the Grid tab-> GridManager tab -> Discovery service, select Edit -> MemberDiscoveryProperties from the Toolbar.
   For networks: From the IPAM tab, select the network check box and click the Edit icon.
2. In the GridDiscoveryProperties,MemberDiscoveryProperties,or(IPv4orIPv6)Network editor, click the Polling tab, and then complete the following in the Basic tab:
   For Probe members and networks, click Override to override the Grid settings.
• SNMPCollection: Select this to execute SNMP protocols to discover and collect information such as traceroute/path collection, vendor and model, SNMP credential collection, routing and ARP tables, switch port data, and VLAN configuration data. If you disable SNMP collection, previously discovered data remains available for viewing; no new data is added and no existing data is removed. Note that some devices may not support SNMP, and some devices also may not enable SNMP by default.
• CLI Collection: Select this if you expect to use Network Insight to discover devices that support CLI connectivity through Telnet or SSH and that you possess admin account information. NIOS can use device admin account logins to query network devices for discovery data collection, including IP configuration, port configuration, routing and forwarding tables, and much more. You must also provide the command-line credentials information as the credentials in the Grid Discovery Properties editor.

  Note: CLI Collection is the default polling method if SNMP is enabled on the member.

• Port Scanning: Select this to probe the TCP ports. Ensure that you go to the Advanced tab to configure more settings for this option. Should you disable Port Scanning, NIOS attempts no port probes other than SNMP on any device.
  • Profile Device: If enabled, NIOS attempts to identify the network device based on the response characteristics of its TCP stack, and uses this information to determine the device type. In the absence of SNMP access, the Profile Device function is usually the only way to identify non-network devices. If disabled, devices accessible via SNMP are identified correctly; all other devices are assigned a device type of Unknown. Profile Device is disabled by default for network polling.
• Smart IPv4 Subnet Ping Sweep: Select this to execute Ping sweeps only on subnetworks that are known to exist but no IPs can be fond within the subnet, such as through ARP or other means.
• Complete Ping Sweep: Select this to enable brute-force subnet Ping sweeps on IPv4 networks. An ICMP ping is broadcast to all addresses in a subnet. Subnet ping sweeps are used as a last resort in the discovery process. Perform a subnet ping sweep if NIOS cannot identify any network devices in a given subnet.
• Subnet ping sweeps should be performed no more that once per day, and will stop on a given subnet once NIOS Discovery locates a network device and is able to collect data from it. Ensure that you configure advanced settings for this option in the Advanced tab.

  Note: Note: NIOS will not perform Smart Subnet ping sweeps on subnets larger than /22. NIOS also will not perform Ping sweeps on IPv6 networks because of the dramatically greater scale of network addresses in the IPv6 realm. The Complete ping sweep differs from the Smart Subnet ping sweep in the following ways: the Complete ping sweep will run only against the specified range; the sweep will run regardless of the range size; and the sweep will run regardless of the number of discovered devices within the specified range.

  NetBIOSScanning: Select this to enable NIOS to collect the NetBIOS name for endpoint devices in the network. This feature can be enabled only by users with SysAdmin privileges. This feature is globally disabled by default (and also for device groups) to prevent unexpected scanning of the network by a new collector.
• Automatic ARP Refresh Before Switch Port Polling: Select this to enable refreshing of ARP caches on switches and switch-routers in the managed network before NIOS performs polling of switch ports. Enabling this feature applies only to switched Ethernet devices. This feature enables more accurate detection of all endpoint devices on L2 switches. Without ARP refresh, some endpoint devices may not be detected. This feature is globally disabled by default. Individual ANPs can also be set to enable or disable this feature.
• Switch Port Data Collection: Select this to enable the Probe member to poll L2 enterprise switches. You can completely disable switch port polling by deselecting this check box. You can also separately schedule polling for switch port data collection as follows:
  • Periodic Polling: Define regular polling time periods. Choose a polling interval of 30 or more Minutes or in between1 and 24 Hours.
  • Scheduled Polling: Schedule recurrent polling based on hourly, daily, weekly or monthly time periods. Choosing this option, click the Calendar icon and a Polling Schedule editor appears; click the Edit icon to make scheduling changes. Choose a recurrence pattern of Once, Hourly, Daily, Weekly or Monthly; in all cases you must choose an ExecutionTime.
3. Save the configuration.

3. Click the Cisco APIC Configuration tab and click the Add icon and complete the following:

• Address: Enter the hostname or IP address of Cisco APIC.
• Protocol: Select HTTP or HTTPS as the protocol. When you select HTTPS, you must upload the corresponding SSL CA certificate to the Grid in order for NIOS to communicate with Cisco APIC, as described in Managing Certificates on page 63.
• Network View: Select the network view to which the device is associated.
• Username: The login name of Cisco APIC.
• Password: The login password of Cisco APIC.
• Comment: Enter additional information Cisco APIC.
