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.

active500EM(config-wireless)#l2tunnel vlan-list 21

 

6.5 show interface wlan

Command: show interface wlan [<ifname> | counter rate] Function: Display statistic information of all centralized tunnels or the tunnels which are identified by name.
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.
