Step 2
| In the text box, enter the name of an access point on your system. Or, you can choose one from the list. This name is used to create a regular expression to create your maps.
Note
| To update a previously created regular expression, select Load and Continue next to the expression and update the expression accordingly.
|
To delete a regular expression, select Delete next to the expression.
|
Step 4
| If your access point‘s name has a delimiter, enter it in the text box and click Generate. The system generates a regular expression that matches your access point’s name based on the delimiter. For example, using the dash (-) delimiter in the access point name San Jose-01-GroundFloor-AP3500i1, produces the regular expression /(.*)-(.*)-(.*)-(.*)/.
If you have a more complicated access point name, you can manually enter the regular expression.
Note
| You are not required to enter the leading and trailing slashes.
|
|
Step 6
| Using the Group fields, assign matching groups to hierarchy types. For example, if your access point is named: SJC14-4-AP-BREAK-ROOM
In this example, the campus name is SJC, the building name is 14, the floor name is 4, and the AP name is AP-BREAK-ROOM.
Use the regular expression: /([A-Z]+)(\d+)-(\d+)-(.*)/
From the AP name, the following groups are extracted:
- SJC
- 14
- 4
- AP-BREAK-ROOM
The matching groups are assigned from left to right, starting at 1. To make the matching groups match the hierarchy elements, use the drop-down list for each group number to select the appropriate hierarchy element.
This enables you to have almost any ordering of locations in your access point names.
For example, if your access point is named: EastLab-Atrium2-3-San Francisco
If you use the regular expression: /(.*)-(.*)-(.*)-(.*)/ with the following group mapping:
- Building
- Device Name
- Floor
- Campus
Automatic Hierarchy Creation produces campus named San Francisco, a building under that campus named EastLab, and a floor in EastLab named 3.
Note
| The two hierarchy types, Not in device name and Device have no effect, but enable you to skip groups in case you need to use a matching group for some other purpose.
Automatic Hierarchy Creation requires the following groups to be mapped in order to compute a map on which to place the access point:

Automatic Hierarchy Creation attempts to guess the floor index from the floor name. If the floor name is a number, AHC will assign the floor a positive floor index. If the floor name is a negative number or starts with the letter B (for example, b1, -4, or B2), AHC assigns the floor a negative floor index. This indicates that the floor is a basement.
When searching for an existing map on which to place the access point, AHC considers floors in the access point’s building with the same floor index as the access point’s name.
For example, if the map SF > MarketStreet > Sublevel1 exists and has a floor index of -1, then the access point SF-MarketStreet-b1-MON1 will be assigned to that floor."

Step 7
| Click Next. You can test against more access points. You may test your regular expression and matching group mapping against more access points by entering the access point’s names in the Add more device names to test against field, and clicking the Add button. You then click the Test button to test each of the access points names in the table. The result of each test is displayed in the table.
If required, return to the previous step to edit the regular expression or group mapping for the current regular expression.
|
Step 8
| Click Next, then click Save and Apply. This applies the regular expression to the system. The system processes all the access points that are not assigned to a map. Note
| You can edit the maps to include floor images, correct dimensions, and so on. When Automatic Hierarchy Creation creates a map, it uses the default dimensions of 20 feet by 20 feet. You will need to edit the created maps to specify the correct dimensions and other attributes. Maps created using Automatic Hierarchy Creation appear in the maps list with an incomplete icon. Once you have edited a map, the incomplete icon disappears. You may hide the column for incomplete maps by clicking the Edit View link.
