Commands for distributed forwarding

Command: clear wireless detected-client [<macaddr>] roam-history
Function: Clear the roaming information of roaming users.
Parameters:

• <macaddr>: MAC address of the roaming client.

Command mode: Admin Mode
Default: None.
Usage guide: With no parameters, clear roaming information of all roaming users. When more than one AC makes up the cluster, this command can only be used in the AC controller of the cluster. If not, there will be a corresponding prompt when executing this command.
Example: Clear roaming information of the user with the MAC address of 08-10-74-ad-93-c8.

Command: dist-tunnel
no dist-tunnel

Function: Enable the distributed tunnel. The no command will disable the distributed tunnel function.
Parameters: None.
Command mode: Network Configuration Mode
Default: Disable distributed tunnel.
Usage guide: In network configuration mode, enable distributed tunnel.
Example: Enable distributed tunnel function of network 34.

active500EM(config-wireless)#network 34
active500EM(config-network)#dist-tunnel

 

Command: dist-tunnel idle-timeout <30-3600>
no dist-tunnel idle-timeout

Function: Configure the tunnel idle timeout value of Home-AP. The no command will restore the default value as 120s.
Parameters:

• <30-3600>: the tunnel idle timeout value for Home-AP; unit is seconds.

Command mode: Wireless Global Configuration Mode
Default: 120s.
Usage guide: Home-AP will inspect the client tunnel idle time to determine whether it is experiencing timeout once every 30 seconds; if so, then the AP sends a releasing tunnel message to the AC, the AC forwards it to the Assoc-AP to release the tunnel, and the client will obtain the IP address again. If idle timeout changed, the new value will be sent to the AP from the AC, and the AP will inspect the tunnel idle time to determine whether it is experiencing timeout after another 30 seconds. If it does, the process described above is repeated.
Example: Set the idle timeout value to be 1200s of Home-AP.

active500EM(config-wireless)#dist-tunnel idle-timeout 1200

 

Command: dist-tunnel max-client <1-8000>
no dist-tunnel max-client

Function: Configure the maximum number of roaming users of Home-AP. The no command will restore the default value as 128.
Parameters:

• <1-8000>: the number of roaming users of Home-AP.

Command mode: Wireless Global Configuration Mode
Default: 128.
Usage guide: If the roaming user?s max number is more than the Home-AP MaxClient setting, then a tunnel message sent from the AC will be unsuccessful. The AP will reply to the AC releasing a tunnel message to the AC. The AC then forwards it to the Assoc-AP or Peer-switch. If MaxClients has changed, the configuration will be sent to the AP. The AP will inspect the tunnel user?s number to determine whether it exceeds the limit; if it does exceed the limit, it will delete users from the user list one by one, starting with the first user, until it does not exceed the limit.
Example: Set the Home-AP MaxClient number to be 256.

active500EM(config-wireless)#dist-tunnel max-client 256

 

Command: dist-tunnel max-timeout <30-86400>
no dist-tunnel max-timeout

Function: Configure Home-AP tunnel timeout value. The no command will reset to the default value of 7200s.
Parameters:

• <30-86400>: for Home-AP tunnel timeout value.

Command mode: Wireless Global Configuration Mode
Default: 7200s.
Usage guide: Home-AP will inspect the wireless client to determine whether it is experiencing timeout once every 30 seconds. When the tunnel set-up time exceeds this value, Home-AP will send a releasing tunnel message to the AC, and the AC will forward it to the Assoc-AP to release the tunnel.
Example: Set the Home-AP tunnel timeout value as 36000s.

active500EM(config-wireless)#dist-tunnel max-timeout 36000

 

Command: dist-tunnel mcast-repl <1-1024>
no dist-tunnel mcast-repl

Function: Configure the number of multicast copying of the Home-AP. The no command will reset to the default value of 128.
Parameters:

• <1-1024>: number of multicast copying of Home-AP.

Command mode: Wireless Global Configuration Mode
Default: 128.
Usage guide: If the roaming users exceed the MaxMcastRepl value, then the tunnel message sent from the AC will be unsuccessful. The AP will reply to the AC with a release tunnel message. The AC will then forward it to Assoc-AP or Peer-switch. If the MaxMcastRepl changes, the configuration will be sent to the AP from the AC. The AP will inspect the correlation tunnel number to determine whether it exceeds the limit; if it does exceed the limit, it will delete the tunnels one by one until it does not exceed the limit.
Example: Set the number of Home-AP multicast copying to 256.

active500EM(config-wireless)#dist-tunnel mcast-repl 256

 

Command: show wireless ap <macaddr> dist-tunnel {statistics | status}
Function: Display the AP distributed tunnel correlation information.
Parameters:

Command mode: Admin Mode
Default: None.
Usage guide: Use this command to check the distributed tunnel statistics or tunnel status of the specified AP.

Parameters:

• <macaddr>: MAC address of the roaming user.

Command mode: Admin Mode
Default: None.
Usage guide: This command can only be for the AC controller of the cluster. If the AC Controller does not exist, there will be a corresponding prompt when executing this command.
