Limitations and Restrictions

MIB File Compatible with Firmware Version 11.0x

The Cisco Aironet access point MIB file (AWCVX-MIB) is supported by access point firmware versions 11.00 and later. Earlier versions of firmware do not support this MIB.

Caveats

Resolved Caveats

The following caveats have been resolved in firmware version 11.05a:

Resolved: CSCdw63011. An error can occur with management protocol processing. Please use this URL for further information:

http://www.cisco.com/cgi-bin/bugtool/onebug.pl?bugid=CSCdw63011

Resolved: CSCdw63031. An error can occur with management protocol processing. Please use this URL for further information:

http://www.cisco.com/cgi-bin/bugtool/onebug.pl?bugid=CSCdw63031

The following caveats were resolved in firmware version 11.05 and are also resolved in version 11.05a:

Resolved: Difficult to end Telnet session (CSCav00156).

When you finish running a Telnet session to the access point you must close the Telnet window to end the session.

Resolved: SNMP account names visible through SNMP (CSCdr70629).

All SNMP account names configured on the access point are visible to all users through SNMP.

Resolved: Network response times might be slow on networks with thousands of client devices (CSCdr95686).

On large, flat networks with thousands of client devices, the access point might respond slowly to network traffic. Segmenting the network into subnets can improve access point performance.

Resolved: 340 series access points sometimes block Telnet access (CSCds22265).

Use the console port or the browser interface to communicate with the access point.

Resolved: Corrupt characters sometimes appear in client names in the Association Table (CSCds56664).

Corrupt characters sometimes appear in the names of clients listed in the access point's Association Table.

Resolved: Links to FTP Server Setup page broken in CLI (CSCds71375).

In the command-line interface, the links to the FTP Server Setup page on the Fully Update Firmware page and the Selectively Update Firmware page do not work.

Resolved: User management passwords corrupted when updating firmware from version 10.12 to 11.0x (CSCdt07632).

When upgrading access point firmware from version 10.12 to 11.0x with user information in the User Manager database, the user passwords are corrupted during the upgrade.

Resolved: Repeater access points do not pass traffic with WEP enabled (CSCdt15869).

Access Points can be set up as repeaters but will not pass traffic when WEP is enabled.

Resolved: SNMP sysObjectID is identical for both 340 and 350 series access points (CSCdt21451).

Because both 340 and 350 series access points have the same SNMP sysObjectID, the devices are both perceived as 340 series access points by a network management platform such as HP OpenView.

Resolved: Multiple access points respond to IPSU queries (CSCdt28674).

When the IP Setup Utility (IPSU) sends a MAC-address query to find an access point's IP address, several access points respond to the query.

Resolved: PSP mode causes slow throughput for Symbol handheld scanning devices (CSCdt32927).

Symbol handheld scanning devices receive poor throughput when using power-save mode (PSP).

Resolved: Protocol filters applied to the access point's Ethernet port are also applied to its radio port (CSCdt34043).

Protocol filters applied to the access point's Ethernet port are also automatically applied to packets received over the access point's radio. For example, a filter set up to block HTTP traffic from the Ethernet also blocks HTTP traffic over the radio even though the user did not set up the filter for radio traffic.

Resolved: FTP Get throughput on workgroup bridge drops after FTP Put (CSCdt42769).

During an FTP put from a workgroup bridge to an access point, the access point's data rate drops to 1 Mbps. Subsequent FTP Gets from the workgroup bridge are performed at 1 Mbps.

Resolved: Access points sometimes lock up when set to use long headers only (CSCdt43310).

350 series access points sometimes lock up when they are set to use long headers and antenna diversity and are associated to 350 series client devices using long headers.

Resolved: Workgroup bridge loses connectivity when roaming from one switch leg to another (CSCdt55661).

When a workgroup bridge roams from one access point to an access point on a different switch leg, the access point to which the workgroup bridge roams does not update the switch with new source information for the workgroup bridge and any of its attached client devices.

Resolved: Access points stop sending beacons when Symbol handheld scanning devices are associated (CSCdt64819).

When several Symbol hand-held scanning devices are associated to the access point, the access point stops sending beacons within two hours.

Resolved: Shared-key authentication not available on repeater access points (CSCdt70175).

Repeater access points use open authentication even when shared-key authentication is selected.

Open Caveats

The following caveats have not been resolved for firmware version 11.05a:

Must restart unit twice to enable standby mode (CSCds36123).

When you set up an access point as a standby unit, follow the instructions on page 7-5 in the Cisco Aironet Access Point Software Configuration Guide. When you complete the instruction steps, return to the Hot Standby page and click Start Hot Standby Mode again. When the unit restarts it is in standby mode.

Access point does not support client devices using LEAP with WEP keys of different lengths (CSCds61358).

The length of the transmit WEP key set on the access point determines the length of the session keys used by LEAP clients. For example, if the transmit key on the access point is a 128-bit key, all LEAP clients associated to the access point must use 128-bit WEP keys.

Password on FTP Server Setup page ignored in command-line interface (CSCds71448).

In the CLI the password for the FTP Server Setup page is ignored. Workaround: Access the FTP Server Setup page through the browser interface.

No address filtering pages in console and Telnet interfaces (CSCdt02327).

You cannot set up MAC address filters through the console and Telnet interfaces. Use the browser interface to create and enable MAC address filters.

Broken help links on access point and bridge CD (CSCdt12716).

If you change the default help root URL on a 350 series access point's Web Server Setup page to use the help files on the Cisco Aironet access point and bridge CD, the help buttons on the AP Radio Port, AP Radio Advanced, AP Radio Hardware, and AP Radio Identification pages will not work. To use the most up-to-date online help, leave the default help root URL at its default setting.

Successful firmware distribution reports error (CSCdt31501).

When distributing firmware to an access point running firmware version 11.01 or later, the distribute status on the distributing access point reports an error even when the distribution is successful. To verify that the distribution was successful, browse to the access point to which you sent the firmware and check that the firmware has been loaded.

Filters can be disabled but not edited from the command-line interface (CSCdt34104).

Although an edit link appears for MAC address filters on the command-line interface, the link does not work. However, you can use the CLI's Ethernet Protocol Filters and AP Radio Protocol Filters pages to disable filters.

Client devices sometimes remain associated to disabled access point instead of switching to standby access point (CSCdt44184).

When the primary access point loses Ethernet connectivity, the standby access point tells the primary access point to shut off its radio so that clients associated to it will associate with the standby access point instead. However, sometimes the primary access point does not shut off its radio and does not disassociate its clients. Workaround: Power cycle both access points and set up Hot Standby again.

Unauthorized reset of access point possible through Telnet (CSCdt47758).

Unauthorized users can reset the access point by opening a Telnet session and pressing Ctrl-x even when the access point's User Manager is enabled.
