From Privileged EXEC mode, apply the modified default profile to the APs that use the default profile (Profile 1).
(switch-prompt)#
wireless ap profile apply 1
After the managed AP updates complete, the L3 Tunnel network is available on all APs that use the default profile. Users
who connect to an AP by using the L3 Tunnel SSID can roam among all APs without traffic interruption.
To test connectivity, make sure you can ping from each AP to the switch loopback IP address and the IP address used by
the routing interface for L3 tunnels. From Privileged EXEC mode, you can enable debugging on the AP with the
wireless
ap debug
<macaddr>
command, which allows you to Telnet to the AP.
Once a wireless client associates with the tunneled subnet, use the ping command and set a large packet size to make sure
you can send the desired MTU size through the tunnel.
From a Windows client, use
-l
<size>
to set the packet size and
-f
to prohibit packet fragmentation, for example:
ping -l 1542 -f 192.168.60.15
From a Unix system, use
-s
<size>
to set the packet size and
-M do
to prohibit packet fragmentation, for example:
ping -s 1542 -M do 192.168.60.15
Example of Configuring L3 Roaming by Using the Web Interface
The following steps shows the procedures to configure the L3 Tunnel Network by using the Web interface on the switch.

Table 92: L3 Tunnel Status Values
L3 Tunnel Status
Description
None
The status might be None for one of the following reasons:
•
The WLAN Operational Status is disabled
•
L3 Tunnel is Disabled
•
The network is not associated with any AP profiles. If you create or edit a network and
configure L3 Tunneling, but there are no VAPs on any AP Profiles that use the network,
the status is None.
Configured
The L3 Tunnel is configured and ready to be applied to the APs that use this profile.
Not Configured - Routing
Disabled
Routing is disabled on the routing interface.
Not Configured - No Routing
Interface
The status might show this value for one of the following reasons:
•
The routing interface for the L3 Tunnel network does not exist.
•
IPv6 is enabled on the routing interface.
•
IP Multicast is enabled on the routing interface.
•
The Tunnel subnet address does not match a routing interface.
In the example in this appendix, the VLAN routing interface has an IP address of
192.168.60.15/24, and the L3 Tunnel Subnet is 192.168.60.0/24, so the tunnel subnet
matches a routing interface.
