Novell ZENWORKS 10 CONFIGURATION MANAGEMENT SP3 - DISCOVERY-DEPLOYMENT-RETIREMENT REFERENCE 10.3 30-03-2010 Deployment Manual page 25

Using fewer discovery technologies reduces the time required to complete the discovery task
but might also reduce the amount of information received.
For detailed information about each technology, see
on page 13.
4 In the IP Addresses to be Excluded panel, specify the IP subnets or address ranges to be
excluded from the discovery.
NOTE: All the discovery tasks inherit the IP address ranges specified at the Management Zone
level. If the IP address range is specified at a task level, the combined ranges of the
Management Zone and discovery task are excluded from the discovery.
You can manually add the IP addresses to be excluded or import the IP addresses to be
excluded from a CSV file.
To manually add the IP address to be excluded:
1. In the Range field, enter the IP address range in one of the following formats:
xxx.xxx.xxx.xxx: Standard dotted-decimal notation for a single address. For
example,
123.45.167.100.
xxx.xxx.xxx.xxx - xxx.xxx.xxx.xxx: Standard dotted-decimal notation for a range of
addresses. For example,
xxx.xxx.xxx.xxx/n: Standard CIDR (Classless Inter-Domain Routing) notation. With
CIDR, the dotted decimal portion of the IP address is interpreted as a 32-bit binary
number that has been broken into four 8-bit bytes. The number following the slash (/
n) is the prefix length, which is the number of shared initial bits, counting from the
left side of the address. The /n number can range from 0 to 32, with 8, 16, 24, and 32
being commonly used numbers. For example,
addresses that start with
Selected IP Ranges list (see the next step), it is automatically expanded to show the
range of addresses in dotted-decimal notation.
2. To add the IP address range to the Selected IP Ranges list, click Add.
To use a CSV list to import an IP address to be excluded:
1. In the Selected IP Ranges list, click Import.
The Import CSV File dialog box is displayed.
2. Click Browse to browse for and select a file that contains a comma-separated or
columnar list of IP addresses.
3. Click OK.
5 In the Network Discovery Settings panel, modify the following settings as necessary:
IP Settings: These settings apply when using the WMI and SNMP discovery technologies.
Initial ping timeout: Specifies how long the discovery technology waits for a response to
an ICMP query (ping).
Maximum ping retries: Specifies the number of times a ping is repeated before giving
up.
Increment ping timeout on retries by: Adds the specified amount of time to each retry.
For example, if the initial ping timeout is 200 milliseconds, the maximum ping retries is 3,
and the increment is 200 milliseconds, the first retry timeout is 400, the second retry
timeout is 600, and the third retry timeout is 800.
