A single word	`cat`	Topics that contain the word "cat". You will also find its grammatical variations, such as "cats".
A phrase. You can specify that the search results contain a specific phrase.	`"cat food"` (quotation marks)	Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase.

Configure an Excluded IP Addresses filter

[This is the Context-Sensitive Help topic for the Discovery Config: Excluded IP Addresses: Excluded Address form.]

This configuration setting instructs NNMi to not add the specified IP addresses to the NNMi database (ignore that information when received from an SNMP agent), not acknowledge any Hints received about them, nor gather Discovery Hints from them, and delete them from the NNMi database during the next Spiral Discovery cycle (if previously discovered). Therefore, NNMi does not monitor or communicate with those addresses.

Caution This filter applies to all nodes that meet the criteria within any Tenant.

The node and interface associated with any address identified in your Excluded IP Address filter still shows up in the topology database and maps.

Sometimes there are IP addresses or ranges of IP addresses in your environment that you do not want NNMi to discover or monitor. For example:

There are multiple Nortel switches in your environment. They each have a non-routable IP address of 192.168.168.168 that is defined by the manufacturer. This special address is used to establish the default VLAN for the switch. However, NNMi discovers this duplicate address and establishes a lot of unnecessary connections on the Layer 3 Neighbor View map.
Your service provider forbids the generation of ICMP or SNMP traffic from your NNMi installation. That range of addresses can easily be excluded to prevent violating your contractual agreement with the vendor.
The Provider Edge (PE) routers have addresses that NNMi ICMP ping commands cannot reach or have addresses that you want to exclude from Subnet views.

Carefully select the addresses for your Excluded IP Addresses filter. Do not populate the Excluded IP Addresses filter with the addresses associated with SNMPv1/SNMPv2c agents or SNMPv3 engines (the Management Addresses).

Caution This filter applies to all nodes in all Tenants. If you exclude an IP address, any duplicates of that address in static Network Address Translation (NAT), dynamic Network Address Translation (NAT), or dynamic Port Address Translation (PAT/NAPT) domains of your network are also excluded.

Tip If you have a large number of IP addresses that you want to exclude from Spiral Discovery, see the nnmdiscocfg.ovpl Reference Page.

To exclude specific IP addresses from the discovery process:

Complete all prerequisites.
Navigate to the Excluded IP Address form.
1. From the workspace navigation panel, select the Configuration workspace.
2. Expand Discovery.
3. Select Discovery Configuration.
4. Select the Excluded IP Addresses tab.
5. Do one of the following:
  - To exclude an address or range of addresses from Spiral Discovery, click the New icon, and continue.
  - To edit an excluded address setting, click the Open icon in the row representing the configuration you want to edit, and continue.
  - To delete an excluded address setting, select a row, and click the Delete icon.
To specify a range of Excluded IP addresses, use one of the following. Pick one address notation style, combinations of wildcards and CIDR notation are not permitted within one address range. You can provide multiple address range settings:
- IPv4 address wildcard notation.
  
  An IPv4 Address range is a modified dotted-notation where each octet is one of the following:
  - A specific octet value between 0 and 255
  - A low-high range specification for the octet value (for example, "112-119")
  - An asterisk (*) wildcard character, which is equivalent to the range expression "0-255"
  The following two IPv4 addresses are considered invalid: 0.0.0.0 and 127.0.0.0
  
  Examples of valid IPv4 address wildcards include:
  
  10.1.1.* 10.*.*.* 10.1.1.1-99 10.10.50-55.* 10.22.*.4 10.1-9.1-9.1-9
- IPv4 Classless Inter-Domain Routing (CIDR) notation.
  
  The CIDR notation specifies the number of consecutive bits in the IPv4 address that must match.
  
  For example, 10.2.120.0/21
  
  NNMi does not support CIDR subnet mask notation such as, 10.2.120.0/255.255.248.0
  
  Example IPv4 Prefix Length Values:
  - 28
    
    Number of Usable IPv4 Addresses: 14 (16-2=14)*
  - 29
    
    Number of Usable IPv4 Addresses: 6 (8-2=6)*
  - 30
    
    Number of Usable IPv4 Addresses: 2 (4-2=2)*
  - 31
    
    Number of Usable IPv4 Addresses: 2
  * Two IPv4 addresses are reserved in each subnet. The first IPv4 address is used for the network itself and the last IPv4 address is reserved for broadcast.
- IPv6 address wildcard notation
  
  (NNMi Advanced) Separate each 16-bit value of the IPv6 address with a colon. The 16-bit value can be any of the following:
  - A specific hexadecimal value between 0 and FFFF (case insensitive).
  - A low-high range specification of the hexadecimal value (for example, 1-1fe).
  - An asterisk (*) wildcard character (equivalent to the range expression 0-ffff).
  The standard IPv6 short-hand notation (::) is allowed to express one or more 16-bit elements of zero (0) values. However, the mixed IPv6/IPv4 dot-notation (for example, 2001:d88::1.2.3.4) is not permitted as an IPv6 address range.
  
  Valid examples of ranges in modified IPv6 address notation include the following:
  
  2001:D88:0:A00-AFF:*:*:*:*
  2001:D88:1:*:*:*:*:*
  2001:D88:2:0:a07:ffff:0a01:3200-37ff
- IPv6 Classless Inter-Domain Routing (CIDR) notation
  
  (NNMi Advanced) The CIDR notation specifies the number of consecutive bits in the IPv6 address that must match.
  
  2001:d88:a00::/44 (equivalent to modified IPv6 address notation 2001:d88:a00-a0f:*:*:*:*:*)
  
  For example, valid IPv6 address ranges in CIDR notation include the following:
  
  2001:d88:0:a00::/56 (equivalent to modified IPv6 address notation 2001:D88:0:A00-AFF:*:*:*:*)
  
  2001:d88:1::/48 (equivalent to modified IPv6 address notation 2001:D88:1:*:*:*:*:*)
Click Save and Close. Spiral Discovery implements your changes during the next regularly scheduled discovery interval. To apply the changes immediately, use Actions > Polling > Configuration Poll.

You can also right-click any object in a table or map view to access the items available within the Actions menu.
