decrease switching time

Hi guys.

I have a project that use 15 ap in a roaming wireless network.
every AP connect to cisco switch with P2P link.
how can i decrease wireless switching time between two AP?

configuration in AP device:
0 name=“wlan1” mtu=1500 mac-address=4C:5E:0C:41:46:71 arp=enabled
interface-type=Atheros AR9300 mode=ap-bridge ssid=“Bwireless” frequency=5745 band=5ghz-a/n
channel-width=20mhz scan-list=default wireless-protocol=any vlan-mode=no-tag vlan-id=1
wds-mode=disabled wds-default-bridge=none wds-ignore-ssid=no bridge-mode=enabled
default-authentication=yes default-forwarding=yes default-ap-tx-limit=0
default-client-tx-limit=0 hide-ssid=no security-profile=profile1 compression=no

configuration on client:
0 R name=“wlan1” mtu=1500 mac-address=4C:5E:0C:63:3F:4F arp=enabled
interface-type=Atheros AR9300 mode=station-bridge ssid=“Bwireless”
frequency=5745 band=5ghz-a/n channel-width=20mhz scan-list=5200-5825
wireless-protocol=any vlan-mode=no-tag vlan-id=1 wds-mode=disabled
wds-default-bridge=none wds-ignore-ssid=no bridge-mode=enabled
default-authentication=yes default-forwarding=yes default-ap-tx-limit=0
default-client-tx-limit=0 hide-ssid=no security-profile=profile1

capsman?

No. I want to run capsman but it doesn’t work i update all Router OS but sometimes some Ap not work in capsman.

I think this depends on an configuratiln fault

do you mean roaming??

I would take a look at Cisco’s Configuration Client Roaming guide: http://www.cisco.com/c/en/us/td/docs/wireless/controller/7-4/configuration/guides/consolidated/b_cg74_CONSOLIDATED/b_cg74_CONSOLIDATED_chapter_01100.html

Perhaps the solution is setting transition time parameters on your roaming client. The guide mentions the ability to set these parameters in the GUI (half way down the page link) by Choose Wireless > 802.11a/n or 802.11b/g/n > Client Roaming. The 802.11a (802.11b) > Client Roaming page appears.

Then see Step 6, in the Transition Time text box, enter the maximum time allowed for the client to detect a suitable neighboring access point to roam to and to complete the roam, whenever the RSSI from the client’s associated access point is below the scan threshold.
The Scan Threshold and Transition Time parameters guarantee a minimum level of client roaming performance. Together with the highest expected client speed and roaming hysteresis, these parameters make it possible to design a wireless LAN network that supports roaming simply by ensuring a certain minimum overlap distance between access points.

The range is 1 to 5 seconds.
The default is 5 seconds.

Hope this guide helps.
