The Device, Interface, and End Host tables can contain huge numbers of records and can be overwhelming to search through. Switch Port Management provides filtering to efficiently cope with the array of data. Using the Filters capability, you can select any data field type displayed in any table, specify a threshold value, and search out the required data. Using this method, you can use any relevant, common-sense networking criteria to single out subsets of records.

1. Display the Switch Port Management table you wish to filter. For example, choose **Devices** **Present**.
2. Click **Filters** just above the top of the table.
3. In the **Select** **a** **New** **Field** drop-down list, choose the table field by which to filter. For example, in a long device list, you might choose **Avail** **Ports** **%**.
4. Choose an **Operator**. For example, you might want to check for all switches that have 20% or less of their ports available. In this case, the **<=** operator is appropriate.
5. In the **Value** field of the Filters dialog, enter the numeric value. This is the numeric threshold by which the data is filtered. The result is a filter by which all records with a count of less than 20% will not appear in the filtered table.
6. Click **Apply** to test the filter. The table will refresh in the background. If you wind up with results you do not expect, check your use of the correct operator or change the numeric threshold.  
The **Capacity** **Summary –** **Ports** page also redraws to show the matching counts for the filter.
7. Click the trashcan (Delete) icon for the filter row to delete a filter. Of course, you can apply more than one filter at a time to the table.

Filter criteria change according to the chosen table information. Devices, Interfaces, and End Hosts all present a different set of table fields by which you can filter their respective bodies of information.
