Wireless LAN Policy

WLANs can be configured as separate policies in respect to the specific needs of different user groups, even when they are not in physical proximity with one another.

Again, <RFS4000> and <RFS6000> model controllers and <NX4500> and <NX6500> series service platforms support a maximum of 32 WLANs. <RFS7000> model controllers support up to 256 WLANs. A <NX9000> Series service platform (<NX9000>, <NX9500> or <NX9510>) supports up to 1000 WLANs. access points can support a maximum of 16 WLANs per model.

To review the attributes of existing WLANs (policies) and, if necessary, modify their configurations:

1. Select Configuration > Wireless > Wireless LANs to display existing WLANs.

2. Refer to the following (read only) information to assess the attributes of the each WLAN available:

   WLAN	Displays the name of each available WLAN. Individual WLANs can selected and their SSID and client management properties modified.
   SSID	Displays the name of the SSID assigned to the WLAN when created or last modified. Optionally, select a WLAN and click the Edit button to update the WLAN's SSID.
   Description	Displays the brief description set for each listed WLAN when it was either created or modified.
   WLAN Status	Lists each WLAN's current status as either Active or Shutdown. A green check mark defines the WLAN as available to clients on all radios where it has been mapped. A red "X" defines the WLAN as shutdown, meaning even if the WLAN is mapped to radios, it's not available for clients to associate.
   VLAN Pool	Lists each WLAN's current VLAN mapping. Mapping a WLAN to more than one VLANs is permitted. When a client associates with a WLAN, the client is assigned a VLAN by load balance distribution. The VLAN is picked from a pool assigned to the WLAN. Keep in mind however, typical deployments only map a single VLAN to a WLAN. The use of a pool is strictly optional.
   Bridging Mode	Displays the bridging mode used by each WLAN. Available bridging modes are Local and Tunnel.
   DHCP Option 82	DHCP Option 82 is commonly used in large enterprise deployments to provide client physical attachment information. Option 82 is used in distributed DHCP server/relay environments, where relays insert additional information to identify the client's point of attachment. A red “X” defines DHCP option 82 as disabled, a green check means its enabled.
   Authentication Type	Displays the name of the user authentication scheme each listed WLAN is using to secure its client membership transmissions. None is listed if authentication is not used within this WLAN. Refer to the Encryption type column if no authentication is used to verify there is some sort of data protection used with the WLAN or risk no protection at all.
   Encryption Type	Displays the name of the encryption type each listed WLAN is using to secure its client membership transmissions. None is listed if encryption is not used within this WLAN. Refer to the Authentication column to verify there is some sort of data protection used with the WLAN or risk using this WLAN with no protection at all.
   QoS Policy	Lists the QoS policy applied to each listed WLAN. A QoS policy needs to be custom selected (or created) for each WLAN in respect to the WLAN's intended client traffic and the voice, video or normal data traffic it supports.
   Association ACL	Lists the Association ACL policy applied to each listed WLAN. An Association ACL is a policy-based Access Control List (ACL) that either prevents or allows wireless clients from connecting to a WLAN. The mapping of an Association ACL is strictly optional.

Use the sequential set of WLAN screens to define a unique configuration for each WLAN. Refer to the following to set WLAN configurations:

• Basic WLAN Configuration
• Configuring WLAN Security
• Configuring WLAN Firewall Settings
• Configuring WLAN Client Settings
• Configuring WLAN Accounting Settings
• Configuring Client Load Balancing Settings
• Configuring Advanced WLAN Settings
