Note PC Cards are not included with your kit and must be ordered as separate items. ------------------------------------------------------------------- Known Problems Link Integrity doesn't recover from after Network server back up link (8666). When network server is offline, the AP2000 can disable the wireless connections and the card LEDs become amber. But when the network server is put back online, the AP-3 cannot bring the wireless cards online, even though the LEDs are green. Clients could not reestablish a connection. A reboot is required to make the AP-3 work again. Web - Failed TFTP operation screen shows "SUCCESSFUL!" (8572 & 8684). If a TFTP image download fails, the web interface displays the text "TFTP Operation Unsuccessful" in the middle of the browser window. However, the browser title says "Configuration Successful" and the 'tab' in the browser window says "SUCCESSFUL!" These 'success' texts should be changed to some form of 'unsuccessful'. CLI - has problems when entering the WEP key in letters the first time (8816). When attempting to enter a 128-bit hexadecimal WEP key that contains hex letters, the CLI user interface does accept enter on the first attempt. A second attempt was required. However, numeric data does not require a second attempt. This problem does not occur in the HTTP or SNMP user interfaces. CLI may display DHCP server IP pool entry values incorrectly. (8831) When entering the IP address pool entry using the following CLI command: set dhcpippooltbl 0 startipaddr 10.1.5.200 width 10 The system took the command and remind to reboot. But the IP entry is shown with Width : -16777206. Although the display is incorrect. The pool functions properly upon reboot. Bronze card works intermittently.(7778) Bronze card does not work at all times in either slot of the AP-2000. Clients may not be able to associate to AP-2000 with Bronze card present. In addition, if bronze cards are present during boot up, the AP-2000 may occasionally reboot. Confirmation window sometimes pops-up another dialog window (4403). When you make a change a separate window pops-up indicating that the change was made successfully. You acknowledge this by selecting the 'ok' button. In some cases the confirmation window does not disappear and causes another dialog window to appear. If another dialog window appears, click the 'ok' button to confirm that you want to close the window. CLI displays some un-readable characters when certain commands are issued (5714). The un-readable characters occur when you press the enter key after the system reboots or if you enter the password incorrectly 3 times. You may also receive un-readable characters when the exit command is issued after changing the IP address of the unit. Cancel button on the web-browser interface pops-up "modifications require reboot" message (7308). When you modify a re-bootable parameter in the web-browser interface (e.g., the HTTP port number) and click the 'cancel' button, the popup message "The modifications that have been made will only take effect after the device is rebooted" appears. This message should not appear when a change is cancelled. Several MIB tables are not aligned properly when displayed in the command line interface (7866). When using the command line interface to manipulate/display data from the MIB tables, data for several tables will not be displayed properly on the HyperTerminal screen. The affected tables are the STATICMP, STATBRIDGETBL, and STPTBL. A System Location value greater than 199 characters in length will be truncated with garbage characters in the command line interface (7844). If you enter a system location string that is longer than 199 characters in length, the portion that extends past 199 characters will be truncated and replaced by garbage characters. MAC Access Control Table allows more than 25 bytes to be entered in the comment field (7847). When adding/editing a MAC address in the MAC Access Control table, the comment field allows you to enter more than 25 bytes in length. The Management Information Browser (MIB) IAPP table values are not being updated properly (7863). When using the web-browser interface, the values displayed on the screen are incorrect. The IAPP tables are not being updated properly and are not in sync with the MIB tables. Radius Access Control: When station on one AP hands over to a second AP a periodic check is still performed (8254). When a station hands off from one AP to second AP a periodic check should no longer be performed. This is not the case. Once the handover takes place and the station is seen on the Ethernet side, a periodic check is still performed based on the time specified in the authorization lifetime parameter. The Learning process does not create or update a dynamic entry in the filtering database (4456). Firmware Overload (4117). When stress testing the AP-3 with extremely large ping (59,400 bytes) and more than seven (7) clients, causes the beacons to drop and some clients to lose connection. After the load is reduced, the firmware recovers. This happens at the same level with our first Access Point product and at even lower levels of stress with some non-Avaya Access Points. The Learning table does not update when clients are inactive/disconnected (8045). When a client is inactive/disconnected for approx. 24 hours, the learning table does not update and remove the client MAC address from the table. The time interval value should be read/write. However, there is no place in the HTTP interface to set this value. Authentication Failure does not generate a trap (7960). RADIUSServerNotResponding does not generate a trap (7961). ------------------------------------------------------------------- Troubleshooting For the most up-to-date, detailed troubleshooting information, refer to the Avaya AP-3 User Guide. ------------------------------------------------------------------- Obtaining Documentation You can access the most recent software and user documentation on the World Wide Web at the following site: http://www.avaya.com ------------------------------------------------------------------- Obtaining Technical Assistance If you encounter problems when installing or using this product, or would like information about our other Avaya Wireless products, please contact your local authorized Avaya Wireless reseller or sales office.
