override-wlan

Configures RF Domain level overrides for a WLAN

Supported in the following platforms:

Syntax

override-wlan <WLAN-NAME> [shutdown|ssid|template|vlan-pool|wep128|wpa-wpa2-psk]
override-wlan <WLAN-NAME> [shutdown|ssid <SSID>|template <TEMPLATE-NAME>|vlan-pool 
<1-4094> {limit <0-8192>}]
override-wlan <WLAN-NAME> wpa-wpa2-psk [0 <WORD>|2 <WORD>]
override-wlan <WLAN-NAME> wep128 [key <1-4> hex [0 <WORD>|2 <WORD>]|transmit-key <1-4>]

Parameters

override-wlan <WLAN-NAME> [shutdown|ssid <SSID>|template <TEMPLATE-NAME>|vlan-pool 
<1-4094> {limit <0-8192>}]
<WLAN-NAME> Configures the WLAN name. If applying RF Domain level overrides to an existing WLAN, specify its name. If creating a new WLAN, specify a name not exceeding 32 characters and representing the WLAN‘s coverage area.
shutdown Shuts down WLAN operation on all mapped radios

ssid <SSID>

 Configures a override SSID associated with this WLAN
  • <SSID> – Specify the SSID (should not exceed 32 characters in length).

Each WLAN provides associated wireless clients with a SSID. This has limitations, because it requires wireless clients to associate with different SSIDs to obtain QoS and security policies. However, a WiNG-managed RF Domain can have WLANs assigned and advertise a single SSID, and yet allow users to inherit different QoS or security policies.
template <TEMPLATE-NAME> Configures a template name for this RF Domain
  • <TEMPLATE-NAME> – Specify the template name (should not exceed 32 characters in length).
vlan-pool <1-4094> {limit <0-8192>} Configures the override VLANs available to this WLAN
  • <1-4094> – Specify the VLAN ID from 1 - 4094.
    • limit <0-8192> – Optional. Sets a limit to the number of users on this VLAN from 0 - 8192. The default is 0.

Controllers and service platforms allow the mapping of a WLAN to more than one VLAN. Wireless clients associating with a WLAN are assigned VLANs, from the pool representative of the WLAN, in a way that ensures proper load balancing across VLANs. Clients are tracked per VLAN, and assigned to the least used/loaded VLAN. Client VLAN usage is tracked on a per-WLAN basis. The maximum allowed client limit is 8192 per VLAN.

 
override-wlan <WLAN-NAME> wpa-wpa2-psk [0 <WORD>|2 <WORD>]
<WLAN-NAME> Configures the WLAN name. If applying RF Domain level overrides to an existing WLAN, specify its name. If creating a new WLAN, specify a name not exceeding 32 characters and representing the WLAN‘s coverage area. After creating the WLAN, configure its override parameters.
wpa-wpa2-psk <PASSPHRASE> Overrides a WLAN‘s existing WPA-WPA2 pre-shared key or passphrase at the RF Domain level. WPA2 is a newer 802.11i standard that provides wireless security that is stronger than Wi-Fi Protected Access (WPA) and WEP.
  • <PASSPHRASE> – Specify a WPA-WPA2 key or passphrase. It is an alphanumeric string of 8 to 64 ASCII characters or 64 HEX characters as the primary string, which both the transmitting and receiving authenticators must share in this new override PSK. The alphanumeric string allows character spaces. The string is converted to a numeric value. This passphrase saves the you the necessity of entering the 256-bit key each time keys are generated.
 
override-wlan <WLAN-NAME> wep128 [key <1-4> hex [0 <WORD>|2 <WORD>]|transmit-key <1-4>]
<WLAN-NAME> Configures the WLAN name. If applying RF Domain level overrides to an existing WLAN, specify its name. If creating a new WLAN, specify a name not exceeding 32 characters and representing the WLAN‘s coverage area. After creating the WLAN, configure its override parameters.
wep128 Overrides a WLAN‘s existing WEP128 keys at the RF Domain level (not the profile level). WEP128 uses a 104 bit key, which is concatenated with a 24-bit initialization vector (IV) to form the RC4 traffic key. WEP may be all a small-business user needs for the simple encryption of wireless data on the WLAN. However, networks that require more security are at risk from a WEP flaw. WEP is only recommended if there are client devices incapable of using higher forms of security. The existing 802.11 standard alone offers administrators no effective method to update keys.
key <1-4> hex [0 <WORD>| 2 <WORD>] Configures the WEP128 key. A total of four keys can be configured.
  • <1-4> – Select the key index from 1- 4.
    • hex – Configures a hexadecimal key
      • <WORD> – Specify the WEP128/Keyguard key (should not exceed 26 hexadecimal characters in length).
transmit-key <1-4> Configures transmit WEP/Keyguard key settings
  • <1-4> – Transmit the key identified by the key index specified here. Specify the index from 1 - 4.
