Software User Manual 12/10/09 D-Link Unified Access System Field WLAN Switch Operational Status WLAN Switch Disable Reason IP Address Peer Switches Cluster Controller Cluster Controller IP Address Total Access Points Managed Access Points Standalone Access Points Rogue Access Points Discovered Access Points Connection Failed Access Points Authentication Failed Access Points Table 276: Global WLAN Status/Statistics Description This status field displays the operational status of the WLAN Switch. The WLAN Switch may be configured as enabled, but is operationally disabled due to configuration dependencies. If the operational status is disabled, the reason will be displayed in the following status field. The WLAN Switch is composed of multiple components, and each component in the system must acknowledge an enable or disable of the WLAN Switch. During a transition the operational status might temporarily show a pending status. If the status is disabled, this field appears and one of the following reasons is listed: • None: The cause for the disabled status is unknown. • Administrator disabled: The Enable WLAN Switch option on the global configuration page has been cleared. • No IP Address: The WLAN interface does not have an IP address. • No SSL Files: The Unified Switch communicates with the APs it manages by using Secure Sockets Layer (SSL) connections. The first time you power on the Unified Switch, it automatically generates a server certificate that will be used to set up the SSL connections. The SSL certificate and key generation can take up to an hour to complete. If routing is enabled on the switch, the operational status might be disabled due to one of the following reasons: • No Loopback Interface: The switch does not have a loopback interface. • Global Routing Disabled: Even if the routing mode is enabled on the WLAN switch interface, it must also be enabled globally for the operational status to be enabled. IP address of the switch. Number of peer WLAN switches detected on the network. Indicates whether this switch is the Cluster Controller for the cluster. Among a group of peer switches, one of the switches is automatically elected or configured to be the Cluster Controller. The Cluster Controller gathers status and statistics about all APs and clients in the peer group. Note: Only the Cluster Controller switch can display managed APs, clients, statistics, and RF Scan databases for the whole cluster. The switches that are not Cluster Controllers can display information only about locally attached devices. The IP address of the peer switch that is the Cluster Controller. Total number of Managed APs in the database. This value is always equal to the sum of Managed Access Points, Connection Failed Access Points, and Discovered Access Points. Number of APs in the managed AP database that are authenticated, configured, and have an active connection with the Unified Switch. Number of trusted APs in Standalone mode. APs in Standalone mode are not managed by a switch. Number of Rogue APs currently detected on the WLAN. When an AP performs an RF scan, it might detect access points that have not been validated. It reports these APs as rogues. APs that have a connection with the switch, but haven't been completely configured. This value includes all managed APs with a Discovered or Authenticated status. Number of APs that were previously authenticated and managed, but currently don't have connection with the Unified Switch. Number of APs that failed to establish communication with the Unified Switch. Document 34CSFP6XXUWS-SWUM100-D7 Monitoring Status and Statistics Page 453
