- Purge expired assets data after: Removes records of discovered assets that are no longer reachable after a specified period of time. The default is set to one day.
- Purge expired device data after: Removes records of discovered network infrastructure devices that are no longer reachable after a specified period of time. The default is set to seven days, a more forgiving value given that devices sometimes require maintenance, upgrades or repairs, or in cases where hosts leave the network on long trips.
- ARP Aggregate Limit: Determines the largest ARP table collectible by discovery. The default is set to 30 ARP table entries (MAC Addresses).
- Route Limit: Limits the size of the routing table that discovery is required to collect from any given device. Some routers can have tables in the hundreds of thousands of entries, and collecting such a large body of data can impose performance problems in the network and in discovery data collection. This setting defaults to 3000, and automatically excludes BGP routes from collectionfromcollection. Consult Infoblox Technical Support before making changes to this value.
- Ping Sweep Timeout (ms): Period of time allowed, in milliseconds, before a beforea Ping times out to any given device.Default is 1000 ms.
- Ping Sweep Attempts: The number of attempts on each address in a Ping sweep before the sweep continues.
- Ping Sweep Frequency: Defaults to 1, because ping sweep should not be executed more than once a day when the feature is enabled at the grid level or for a given discovery range. This setting affects the Smart Ping Sweep and Complete Ping Sweep features under Grid Discovery Properties.
- ARP Cache Refresh: Defines the time period between ARP refreshes by Network Insight across all switch ports. Before any other switchport otherswitchport polling and discovery operations take place (including any global discovery polling operations initiated by the administrator), another ARP refresh is carried out by the Probe appliance regardless of the time interval. The default is five minutesfiveminutes, because switch forwarding tables are frequently purged from LAN switching devices. (The default on Cisco switches is five minutes/300 seconds.) Network Insight primarily uses ARP Cache refreshes to improve the accuracy of end-device discovery. Without this feature, some endpoints may not be discovered and cataloged.
- Ignore Conflict Duration: Used when resolving conflicts and when choosing the option to Ignore the conflict when resolving it. The length of time during which conflicts is ignored is defined with this settings.Increments can be defined in Hours or Days.
- Number of discovered unmanaged IP addresses per notification: The maximum number of unmanaged IP addresses that the appliance discovers appliancediscovers before it sends SNMP and email notificationsandemailnotifications, if enabled. The appliance resets the counter after it hits this number and sends notifications. The default is 20.
- Interval between notifications for discovered unmanaged IP addresses: This number determines how often the appliance sends SNMP and email notifications, if enabled, when it discovers the maximum number of unmanaged IP addresses (configured for Number of discovered unmanaged IP addresses per notification ). This is the time interval between two notifications for discovered unmanaged objects. Select the time unit from the drop down menu. The default is five minutes.
- Disable discovery for networks not in IPAM: Enabling this setting disallows Network Insight from executing discovery on any infrastructure networks that are not presented in the Infoblox IPAM system; e.g. present and DNS Lookup Option: Specify whether you want to perform a reverse DNS lookup from discovered IP addresses. Select one of the following from the drop-down list:
Network Devices: Select this to resolve network device (switches and routers) IP addresses. This option is selected by default.
Network Devices and End Hosts: Select this to resolve both network device (switches and routers) and end host IP addresses.
Off: Select this to turn off reverse DNS lookups for discovered IP addresses.
- DNS Lookup Throttle: This is the value in a percentage that throttles the traffic on the DNS servers. Setting a lower value reduces the number of requests to DNS servers. You can specify a value between 1 and 100. The default value is 100.
- Disable discovery for networks not in IPAM: Enabling this setting disallows Network Insight from executing discovery on any infrastructure networks that are not presented in the Infoblox IPAM system; e.g. present and managed in a network view or network container.
- Authenticate and poll using SNMPv2c or later only: For credential discovery and device polling exclusively using SNMPv2c and up, preventing use preventinguse of SNMPv1, enable this check box.
- Use DHCP Routers as Seed Routers: Select this so the Probe members can use the default gateways for associated DHCP ranges and networks as seed routers to more quickly discover and catalogue all devices (such as endpoint hosts, printers and other devices). All such default gateways are automatically leveraged by discovery, and no further configuration is necessary unless you wish to exclude a device from usage.
Note: Check for a list of configured DHCP seed routers for any discovery Probe member in the Seed tab –> Advanced tab of the Member Discovery Properties editor. - Log IP Discovery events in Syslog: Sends a message to the configured Syslog service when an IP address of an active host is discovered.
- Log network discovery events in Syslog: Sends a message to the configured Syslog service when a network discovery process takes place in the Grid.
