Switch/Hub Ports

Top Previous Next

Use Switch/Hub Ports Reports to obtain a list of managed switches and hubs and the port number, Ethernet address, and IP addresses for each connected device.

Click on the Switch/Hub Ports Report toolbar icon or select New>Switch/Hub Ports in the Report menu to create a Switch/Hub Ports Report. Once selected, the Switch/Hub Ports Wizard is displayed, allowing you to select the switches, hubs and the schedule to run the report.

Some switches are set by default to flush their Ethernet data relatively frequently. If your Switch/Hub Port reports are not as complete as they should be, consider running the report immediately after creating a new map that includes those end nodes or turn on the Continuous Scan option.

The Switch/Hub Ports report includes the following information:

Switch/Hub Name: name of the switch or hub node, usually the domain name but may be the SNMP machine name (repeats for each port of the device).

IP Address: the IP address of the switch or hub (repeats for each port of the device).

Port Index: the device's internal number for indexing each port. For hubs, these will be unique across the hub. For switches, these may be repeated depending on how many Ethernet addresses have been routed through this port.

Port Description: an optional, usually more descriptive name for the port, as provided by the switch or hub.

Physical Address: the Ethernet address of the device(s) connected to this port. For hubs, there will be only one Ethernet address, which is the last Ethernet address that transmitted data on the port. For switches, there may be multiple rows, each with a different Ethernet address. If a switch port is duplicated this could mean several things:

•	this is an uplink or downlink port connecting switches together and the port will list some or all of the up or downstream Ethernet addresses.

•	two or more devices with different Ethernet addresses have been connected to this port.

•	there is an unmanaged switch or hub uplinked to the port and several nodes with different Ethernet addresses are connected to that unmanaged switch or hub.

Mapped IP Address: LANsurveyor attempts to find the IP address associated with the Ethernet address present in the Physical Address column. This column may be empty if the associated node is down or hasn't communicated via Ethernet for a long period (switch/hub configuration-dependent).

Mapped Node Name: a name associated with the IP address of the previous column, usually the domain name.
