Main Help Topics

This page controls the total number of devices that can be listed in the Association Table and the amount of time the device continues to track each class when an access point or bridge is inactive.

Settings

Handle Station Alerts as Severity Level

This setting determines the Severity Level at which Station Alerts are reported in the Event Log. This setting also appears on the Event Handling Setup page. You can choose from four Severity Levels:

• Fatal Severity Level (System, Protocol, Port) -- Fatal-level events indicate an event that prevents operation of the port or device. For operation to resume, the port or device usually must be reset. Fatal-level events appear in red in the Event Log.
  
  
• Alert Severity Level (System, Protocol, Port, External) -- Alert-level messages indicate that you need to take action to correct the condition and appear in magenta in the Event Log.
  
  
• Warning Severity Level (System, Protocol, Port, External) -- Warning-level messages indicate that an error or failure may have occurred and appear in blue in the Event Log.
  
  
• Information Severity Level (System, Protocol, Port, External) -- Information-level messages notify you of some sort of event, not fatal (that is, the port has been turned off, the rate setting has been changed, etc.) and appear in green in the Event Log.

Maximum Number of Bytes Stored per Alert Packet

This setting determines the maximum number of bytes the device stores for each Station Alert packet when packet tracing is enabled. If you want to see the entire contents of each packet, enter 1600; if you want to see only the packet header, enter 64.

Maximum Number of Forwarding Table Entries

This setting determines the maximum number of devices that can appear in the Association Table.

Rogue AP Alert Timeout (minutes)

When an access point detects a rogue access point, it sends an alert message to the system log. This setting specifies the amount of time in minutes the access point transmits the alert message. When the timeout is reached, the access point stops sending the alert message.

Rogue AP Alert Timeout (minutes)

When an access point detects a rogue access point, it sends an alert message to the system log. This setting specifies the amount of time in minutes the access point transmits the alert message. When the timeout is reached, the access point stops sending the alert message.

Aironet Extended Statistics in MIB (awcTpFdbTable)

Use this setting to enable or disable the storage of detailed statistics in the bridge’s memory. When you disable extended statistics you conserve memory, and the bridge can include more devices in the Association Table.

Map Multicast Entries to Broadcast Entry

Use this setting to make the access point or bridge more virus resistant. Some viruses send entire 1000+ blocks of multicast MAC addresses to the network, which overwhelms the access point's forwarding table. Setting this parameter to enabled maps all multicast MAC addresses into the broadcast address (without changing the packet's MAC address).

Block ALL Inter-Client Communications (PSPF)

Public Secure Packet Forwarding (PSPF) prevents client devices associated to a bridge or access point from inadvertently sharing files with other client devices on the wireless network. It provides Internet access to client devices without providing other capabilities of a LAN. With PSPF enabled, client devices cannot communicate with other client devices on the wireless network. This feature is useful for public wireless networks like those installed in airports or on college campuses.

Note The PSPF feature is available in firmware versions 11.08 and later, which are available on Cisco.com. You can download Cisco Aironet firmware releases at http://www.cisco.com/public/sw-center/sw-wireless.shtml.

Default Activity Timeout (seconds) Per Device Class

These settings determine the number of seconds the device continues to track an inactive device depending on its class. A setting of 0 tells the device to track a device indefinitely, no matter how long it is inactive. A setting of 300 equals 5 minutes; 1800 equals 30 minutes; 28800 equals 8 hours.
