Global Controller Parameters

Use this page to configure the controller. You can also review controller information.

To configure global controller parameters:

1. In the Description box, type a description for the controller. The description is for information only.

   The description can be up to 256 characters long.

2. In the Location box, type the location of the controller. The location is for information only.

   The location can be up to 127 characters long.

3. In the Contact box, type the name of the contact person or group for the controller. The contact is for information only.

   The contact name can be up to 127 characters long.

4. In the Automatic AP Upgrade list, select one of the following:
   • On: Ensures the AP image is automatically upgraded to the same level as the controller when an AP joins the WLAN. This is the default setting..
   • Off: Disables the Automatic AP Upgrade feature. APs must be upgraded manually.
5. In the DHCP Server boxes, type the IP address to which 802.11 client DHCP requests are forwarded.
6. In the Statistics Polling Period box, type the amount of time that elapses before the controller polls for information (for example, the number of packets passed or dropped), and as a result, refreshes the Web UI page with updated information.

   The value can be from 5 to 65,535 seconds. Specifying a value of zero (0) disables polling. The default is 60 seconds.

7. In the Audit Polling Period box, type the amount of time that elapses before the controller collects information about access points.

   The value can be from 5 to 65,535 seconds. Specifying a value of zero (0) disables auditing.

8. In the Default AP Init Script box, type the name of the default initialization script to be run for access points that have no script specified. Do not include an absolute path when specifying the script. A maximum of 64 characters is allowed.

   The script must already be located in /opt/meru/ATS/scripts for the script to be used.

9. In the DHCP Relay Passthrough, select one of the following:
   • On: Enables the DHCP Passthrough; the default setting where DHCP packets are passed through the controller unchanged. With this option,  you must configure DHCP relay on any routers between the 802.11 clients and the DHCP server. With this setting, the DHCP Server IP address field in Step 6. is ignored.
   • Off: Disables the DHCP Passthrough. With this setting, DHCP relay is performed to the DHCP Server specified in Step 6.
10. In the Management by wireless stations list, select one of the following:
    • On: (Default) Allow wireless stations to change the controller configuration 
    • Off:  Block management changes to the controller by wireless stations and allow only wired connection changes
11. In the Controller Index field, if the Personal AP feature is to be used, enter a number from 0 to 31 to represent a unique identifier for this controller; otherwise leave at 0. Also, remember to select Per Station BSSID for the Virtual Cell Type option in the ESS Profile configuration. 
12. In the Topology Information Update list, select one of the following:
    • Off: (Default) The controller does not collect topology information.
    • On: Enables the Topology Information Update feature that allows the controller to collects the information that is used for the Topology-related displays in the Monitor module.
13. In the FastPath Mode list, select one of the following:
    • On: (Default) Accelerates the rate that packets move through the Ethernet interface, based on identification of an IP packet stream. When FastPath is enabled, the beginning of the IP packet stream is processed by the controller, and all subsequent packets of the same stream are forwarded according to the disposition of the initial packets, without being processed by the controller. This offloads a significant amount of processing from the controller.
    • Off: Disables FastPath Mode. This should be the case when the capture-packets command is to be run, as the two are incompatible.
14. In the Bonding Mode list: select one of the following:
    • Single: Combines all MC4100 Ethernet ports into one port for accelerated throughput.
    • Dual: Combines MC4100 Ethernet ports into two ports.
15. In the AP150 Vcell list, select one of the following:
    • Enable: (Default) Allows the formation of an AP150 Virtual Cell, which is a group of AP150 access points on the same channel sharing the same BSSID. Only AP150 models are supported within the AP150 Virtual Cell.
    • Disable: Disables AP150 Virtual Cells.
16. In the DFS (Dynamic Frequency Selection) drop-down list, select one of the following:
    • Enable: (Default) For installations within the United States, channels 52-64 (5.25-5.35 GHz) and 100-140 (5.47-5.725 GHz) cannot conform to newly implemented DFS regulations, protecting radar from interference on these channels.
    • Disable: DFS is not enforced.
    • Indicate the number of minutes of inactivity that causes a station to lose connection.
17. Indicate the number of minutes of inactivity that causes a station to time out .
18. Click OK.
