Connecting the Cisco 1500 Series Mesh Access Points to the Network

Note

To override the globally configured DCA channel width setting, you can statically configure an access

point's radio for 20-MHz mode on the 802.11a/n Cisco APs > Configure page. If you ever change the

static RF channel assignment method to Global on the access point radio, the global DCA configuration

overrides the channel width configuration that the access point was previously using.

This page also shows the following nonconfigurable channel parameter settings:

• Channel Assignment Leader—The MAC address of the RF group leader, which is responsible for channel

assignment.

• Last Auto Channel Assignment—The last time RRM evaluated the current channel assignments.

Step 11

In the DCA Channel List section, the DCA Channels field shows the channels that are currently selected. To choose a

channel, select its check box in the Select column. To exclude a channel, deselect its check box.

Range: 802.11a—36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 132, 136, 140, 149, 153, 157, 161, 165, 190,

196?802.11b/g—1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11

Default: 802.11a—36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 132, 136, 140, 149, 153, 157, 161?802.11b/g—1,

6, 11

These extended UNII-2 channels in the 802.11a band do not appear in the channel list: 100, 104, 108, 112, 116,

Note

132, 136, and 140. If you have Cisco Aironet 1500 series mesh access points in the -E regulatory domain, you

must include these channels in the DCA channel list before you start operation. If you are upgrading from a

previous release, verify that these channels are included in the DCA channel list. To include these channels in

the channel list, select the Extended UNII-2 Channels check box.

Step 12

If you are using AP1500s in your network, you must set the 4.9-GHz channels in the 802.11a band on which they are to

operate. The 4.9-GHz band is for public safety client access traffic only. To choose a 4.9-GHz channel, select its check

box in the Select column. To exclude a channel, deselect its check box.

Range: ?802.11a—1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26

Default:?802.11a—20, 26

Step 13

Click Apply to commit your changes.

Step 14

To reenable the 802.11a or 802.11b/g network, follow these steps:

a) Click Wireless > 802.11a/n or 802.11b/g/n > Network to open the 802.11a (or 802.11b/g) Global Parameters page.

b) Select the 802.11a (or 802.11b/g) Network Status check box.

c) Click Apply to commit your changes.

Step 15

Click Save Configuration to save your changes.

To see why the DCA algorithm changed channels, click Monitor and then View All under Most Recent Traps.

Note

The trap provides the MAC address of the radio that changed channels, the previous channel and the new channel,

the reason why the change occurred, the energy before and after the change, the noise before and after the

change, and the interference before and after the change.
