Table of Contents
6.1 clear counters
Parameters
-
<ifname>: centralized tunnel name.
Command mode: Admin Mode

6.2 debug wireless cl2tunnel error
no debug wireless cl2tunnel error <FF-FF-FF-FF-FF-FF>
Function: Enable/disable centralized forwarding error debug information.
Parameters:
-
<FF-FF-FF-FF-FF-FF>: MAC address of the AP opposite to the tunnel.
Command mode: Admin Mode
Default: None.
Usage guide: After enabling debugging, the error information of creating, deleting, and configuring centralized tunnel will be printed.
Example: Enable error debugging of centralized tunnel in APs whose MAC address is f8-f7-d3-00-03-a0.

6.3 debug wireless cl2tunnel internal-info
no debug wireless cl2tunnel internal-info <FF-FF-FF-FF-FF-FF>
Function: Enable/disable the internal debug information of centralized forwarding.
Parameters:
-
<FF-FF-FF-FF-FF-FF>: MAC address of the AP opposite to tunnel.
Command mode: Admin Mode
Default: None.
Usage guide: After enabling debugging, the internal information of creating, deleting, and configuring centralized tunnel will be printed to locate the error.
Example: Enable internal debugging information of the centralized tunnel in APs whose MAC address is f8-f7-d3-00-03-a0.
active500EM#debug wireless cl2tunnel internal-info f8-f7-d3-00-03-a0 internal WD_LEVEL_CENTTNNL_INFO debug is on MAC: f8-f7-d3-00-03-a0 internal WD_LEVEL_CENTTNNL_INFO debug is on
6.4 l2tunnel vlan-list
no l2tunnel vlan-list <1-4094>
Function: Add a VLAN to tunnel VLAN list. The no command deletes a VLAN from tunnel VLAN list.
Parameters:
-
<1-4094>: ID of VLAN added to tunnel VLAN list.
Command mode: Wireless Global Mode
Default: Tunneled VLAN list is free.
Usage guide: Add a VLAN to the tunnel VLAN list. All user data packets that belong to this VLAN run CAPWAP centralized tunnel.
Note: Managed packets should not forward through this tunnel.
Example: Add VLAN 21 to tunnel VLAN list.
active500EM(config-wireless)#l2tunnel vlan-list 21
6.5 show interface wlan
Parameters:
-
<ifname>: centralized tunnel name.
Command mode: Admin Mode
Default: None.
Usage guide: If the tunnel name is entered, print flow statistic of the identified tunnel. If the tunnel name is not entered, print flow statistic of all tunnels. Counter rate shows rate statistic information of all tunnel ports. It is configured as number and bytes of packets that are input or output in 5 minutes or 5 seconds.
Example: Display flow statistic of all tunnels in the system.
active500EM#show interface wlan
capwaptnl2
5 minute input rate 630 bits/sec, 1 packets/sec
5 minute output rate 2587 bits/sec, 3 packets/sec
The last 5 second input rate 0 bits/sec, 0 packets/sec
The last 5 second output rate 448 bits/sec, 0 packets/sec
Input packets statistics:
5351 input packets, 363868 bytes
