Select the → menu item to customise various aspects of sFlowTrend-Pro.
Use the → menu item, View tab, to tell sFlowTrend-Pro how you would like your switches and their interfaces to be displayed and whether end hosts are identified using IP addresses or DNS names.
Switches can be displayed using one of the following options:
- SNMP IP address
- The IP address that sFlowTrend-Pro uses to communicate with the switch via SNMP
- sFlow agent address
- The IP address that is used by the sFlow agent on the switch to uniquely identify the switch.
- DNS name
- The domain name obtained from the reverse DNS lookup of the SNMP IP address of the switch. If the reverse DNS lookup fails, the SNMP IP address will be used instead.
- sysName
- The SNMP sysName obtained from the SNMP MIB. If sFlowTrend-Pro cannot communicate with the switch using SNMP (see Section 9.1.7, “sFlowTrend-Pro cannot communicate with the switch using SNMP”), then SNMP IP address will be used instead.
If the SNMP IP address or the sFlow agent address option is chosen, the switches will be listed in numerical order in the Switch selector in the Charts and Interfaces tabs. For other options, the switches will be listed in alpha-numeric order, even if an IP address is shown because the name is not available.
Interfaces can be displayed using one of the following options:
- ifIndex
- The integer that the switch uses to uniquely identify the interface.
- ifName
- The friendly name assigned to the interface, identifying the card/slot. For example A1, ethernet1/1. If sFlowTrend-Pro cannot communicate with the switch using SNMP (see Section 9.1.7, “sFlowTrend-Pro cannot communicate with the switch using SNMP”), then the ifIndex will be used instead.
- ifAlias
- A string administratively assigned to the interface often giving useful information about its purpose. For example "Connection to servers". If sFlowTrend-Pro cannot communicate with the switch using SNMP (see Section 9.1.7, “sFlowTrend-Pro cannot communicate with the switch using SNMP”), or the ifAlias is not assigned, then ifIndex will be used instead.
If the ifIndex option is chosen, the interfaces will be listed in numerical order in the Interface selector in the Charts tab. For other options, the interfaces will be listed in alpha-numeric order, even if the ifIndex is shown because the name is not available.
Select the → menu item, SNMP tab to configure the SNMP community string which will be used for all switches. This community string will be used when querying switches for the friendly names for the switches and interfaces. It will also be used as the read/write community string when sFlowTrend-Pro uses SNMP to configure a switch to send sFlow
This global setting can be explicitly overridden for a
specific switch (see
Section 8.1, “Configuring switches in sFlowTrend-Pro 
”).
Select the → menu item, Advanced tab to view and configure some less commonly used settings:
- sFlowTrend home directory
-
Allows you to change the directory used by sFlowTrend-Pro for storing information. The directory is configured differently, depending on whether you are running sFlowTrend-Pro as an an application, or as a service.
If you are running as an application, then
the home directory is used to store traffic
and log data, and
custom configuration
information. If you have enabled user
authentication (see
Section 8.3, “Configuring user authentication ”,
then only Administrators
can change the home directory.
If you change the home directory,
all currently saved
traffic data and custom
configuration information will be lost.
sFlowTrend-Pro must be restarted for the
change to take effect.
If you are running sFlowTrend-Pro
as a service,
then two home directories are shown in
advanced settings: one for the client, and one
for the server:
- sFlowTrend-Pro home directory
- This allows the home directory for the current client to be changed. The client home directory is used for log files, and any custom configuration that is applicable to the client. The client needs to be restarted for changes to the home directory to take effect.
- sFlowTrend-Pro server home directory
- Displays the home directory used by the server. The server home directory is used to store traffic and log data, and custom configuration information. This directory cannot be changed from within sFlowTrend-Pro; it is entered when installing sFlowTrend-Pro. To change the directory, you can reinstall sFlowTrend-Pro.
- Restore warnings
- Ticking this checkbox will cause sFlowTrend-Pro to display warnings asking you to confirm actions, for example when deleting switches or when exiting sFlowTrend-Pro. When these warnings are shown, you can ask sFlowTrend-Pro not to show these warnings again. This checkbox can be used to restore the behaviour of showing warnings.
Select the → menu item, Advanced sFlow tab to view and configure some less commonly used sFlow related settings:
- sFlow collector address
- This selection list allows you to select the network interface and associated IP address on the system running sFlowTrend-Pro that will be used to receive sFlow. If you are using a CLI to configure sFlow on your switches, make sure that you use the selected IP address as the destination or collector address for sFlow when you configure the switch (see Section A.1, “Configuring switches to send sFlow”).
- sFlow UDP port
- This allows you to change the UDP port that sFlowTrend-Pro will listen on to receive sFlow. If you are using a CLI to configure sFlow on your switches, make sure that you configure the switch to send sFlow to this UDP port (see Section A.1, “Configuring switches to send sFlow”).
