Discovery

"Discovery " category lets you change configurations on subnet auto-discovery funciton.

Table 1: Discovery
Item Name	Contents
PING	Use individual addresses sequentially The plugin starts a discovery process by sending a Ping packets to each unicast address in the subnet one by one. (default) Apply exclusions Perform a scan by including or excluding devices based on the "exclusion file". Refer to exclusion file for more details. Edit Displays the page for editing the exclusion file. Upload Upload the exclusion file you created locally.
Retry at Discovery	Retry Count for PING Specifies the number of retries when communication fails when obtaining information via Ping or SNMP. The default is 2 times. Timeout Value for PING When obtaining information via Ping or SNMP, specify the wait time before assuming that communication has failed. The default is 1 second. Use same values for SNMP Check this box if you want to use the same retry interval and timeout value when retrieving information via SNMP as when searching by Ping. The default is checked. Retry Count for SNMP Specifies the number of retries to be performed when communication fails when obtaining information via SNMP. The default is 2 times. Timeout Value for SNMP Specifies the wait time before determining that communication has failed when obtaining information via SNMP. The default is 1 second.
Apply	Apply the discovery settings changes.

Exclusion file

If you select "Apply exclusions" in "PING" on the "Discovery" page, the devices to be discovered are determined based on the host, model, and IP Addresses listed in the "exclusion file" instead of automatically detecting IP nodes by Ping.

◼ Example of description



# sample exclude file data ↓

192.168.1.0/24 ↓

exclude 192.168.1.1-31 ↓

exclude 192.168.1.200-192.168.1.239 ↓

192.168.1.10-29 ↓

tq6403gen2 ↓

exclude tq5403 ↓

1.3.6.1.4.1.207.1.13.46 ↓

The format of the exclusion file is as follows:

Filename can be any.
Write one definition per line.
Lines starting with "#" and empty lines are ignored.
The definition written on the line is specified by either host or model as described below, and devices that match the definition are added to the discovery targets.
- Specify host
  Hosts can be specified by individual IP Addresses, IP Address ranges, subnets, or host names.
  - Individual IP Address
    Specify the IPv4 Addresses of the devices to be included in the discovery.
  - IP Address Range
    Specify a range of IPv4 addresses using a hyphen (-).
    You can specify either the first and last addresses, such as "192.168.1.1-192.168.1.5", or you can specify a range of just one octet, such as "192.168.1-10.32".
  - Subnet
    Specify the IPv4 network address and mask length separated by a slash (/).
    For example, "192.168.1.0/24", "192.168.1.1-192.168.1.254", and "192.168.1.1-254" all mean the same thing.
  - Hostname
    Attempts to resolve hostnames to IPv4 addresses using DNS. You can also specify the host name using the FQDN.
    If an IPv4 Address cannot be obtained, it is ignored.
- Model specification
  The models are compared based on the sysObjectID of the MIB obtained from the device.
  When you enter a model name, the sysObjectID is compared with the model name (e.g. atx90024XT, tq6403gen2, etc.) converted from the compiled contents of the MIB file registered in the SNMP Plug-in.
  If you want to specify a device whose MIB is not registered or compiled in the SNMP Plug-in, you can directly specify the model ID in OID format, such as "1.3.6.1.4.1.207.1.13.46".
  Also, if you write it in OID format followed by an @ sign, any sysObjectID obtained from the device that starts with the specified string will be considered a match. For example, if you specify "@1.3.6.1.4.1.207", any sysObjectID that begins with "1.3.6.1.4.1.207" will be considered to match the definition.
If you write "exclude " at the beginning of a line, any devices that match the definitions that follow on the line will be excluded from the search.
Any conditions on a line that do not begin with "exclude" are considered to be included in the search.
If both an include and an exclude definition match, the definition written further down in exclusion file takes precedence.
For example, if you write it as follows, 192.168.1.32 to 192.168.1.254 are searched.
If you write the following in the opposite order, the exclusion range is larger than the exclusion range and the exclusion settings are ignored.
As a result, all addresses from 192.168.1.1 to 192.168.1.254 are searched.

SNMPv3 Trap Receive

"SNMPv3 Trap Receive" category lets you configure SNMP Parameters used for receiving SNMPv3 traps.

Table 2: SNMPv3 Trap Receive
Item Name	Contents
Parameter List	Shows a list of SNMP Parameters used for receiving SNMPv3 traps.
Add	Lets you add or edit SNMP Parameters used for receiving SNMPv3 traps. The SNMP Parameters created in SNMP Parameter List are displayed in the drop-down list. Selecting one adds it to the "Parameter List".
Delete	Excludes the parameters selected in the "Parameter list" from being received. It just removes the parameter from the list. It does not delete the parameter definition.

Misc

The timezone is configured on the Misc page.

Table 3: Misc
Item Name	Contents
Timezone	Configure the time zone for the time displayed by the %time parameter of the Action Command. Select the appropriate item from the pull-down menu. Note that the time displayed on various SNMP plugin pages is not affected by this setting and is shown according to the time zone setting of the operating system of the PC being used.
Apply	Applies the timezone selected in "Timezone".
