Switch VLAN Probe

The VLAN probe function utilizes DHCP client on the switch to check for and display IP connectivity on a specified VLAN.

Note

Note

The VLAN probe is skipped when the selected VLAN has a static IP address or is DHCP enabled.

Use this task to locate a VLAN in a complex network with multiple VLANs. You can also trigger VLAN probe for a Switch Engine device through the topology map.

To verify the VLAN probe results for a selected device:

  1. Go to Manage > Devices select the associated device.
  2. Select Utilities > Tools > Switch VLAN Probe.
  3. Configure the following settings:
    VLAN Range
    Indicates the range of VLAN IDs to probe. Enter the start and end values. You can enter up to five ranges, separated by commas, up to a total range of 12. Range numbers cannot overlap. For example, 1,2-7,8,9-12.
    Probe Retries
    Indicates the number of probe retries. Valid values are 1-10.
    Timeout
    (Optional) Indicates how long to wait for a reply from each probe. Valid values are 5 to 60 seconds.
  4. Select Start to start a probe.
  5. Select Stop to stop a probe before it is complete.
  6. Select Clear to clear entries for a probe.

When the VLAN probe is complete, a table shows the host name, MAC address, available VLANs, unavailable VLANs, and their status.
