Find Endpoints in a Subnet

Scenario:Find all endpoints currently on a subnet.

1. Click the Device Tracker tab, if not already selected.
2. Locate UDT Search.
3. Click Menu in the search box, and then select the desired option(s) for the search.

   MAC addresses are stored without formatting; you can successfully search for a MAC address with format xxxx.xxxx.xxxx or xx-xx-xx-xx-xx-xx or xx:xx:xx:xx:xx:xx.

4. Enter the desired term for the search.

   This example uses IP address 10.199.3.* as the target subnet.

   In this case, you are searching for an exact match. Specific matches are required sought unless wildcards are used in the search term. This means that if you search for laptop and there is a machine named laptop01, you will not find it unless you search for laptop01 or laptop* (or other valid wildcard search).

   More wildcard examples:

   • Fa1*: (when used with Port Number search option) matches any port number that begins with Fa1 followed by any characters.
   • MAC Address: 00:0C*
   • IP Address: 10.10.10.*
   • Cisco3750-* (assuming each of three stacked switches were added as individual devices, using a common naming convention like Cisco3750-1, Cisco3750-2, Cisco3750-3; in this search, you would select the ‘Connected To' drop-down list beside Search)
5. Press Enter or click search. The search results are displayed in a scrollable, tabular view:

   Match Item	Match Type
   10.199.3.1	Endpoint IP Address
   10.199.3.10	Endpoint IP Address
   10.199.3.100	Endpoint IP Address
   10.199.3.101	Endpoint IP Address
   10.199.3.102	Endpoint IP Address
   10.199.3.103	Endpoint IP Address
   ...	...

6. From the search results, you can select an item, and then click Add To Watch List in order to add the item to the device watch list.
