Customer Release Notes

Firmware Release 5.0.11.4:

When configuring the Web portal and saving the default login page, remove everything between the quotes in the Action value of the form tag in the HTML code.

Resolved an issue where the Access Point buffers were filling up with Rogue Detection messages.

Resolved an issue when a wireless client was previously connected to an SSID (WebAAA, last-resort), then switched to a new bonded auth SSID, the machine auth phase was skipped.

Resolved an issue when rebooting the RAS via the CLI command ―reset system‖ does not generate a 'warm start' SNMP. Instead, a 'cold start' trap is sent.

Resolved an issue when clients who authenticated to a switch with a low bias DAP moved to the high bias switch when the switch became available.

Resolved an issue where using the same port for SSH and Telnet access caused the RAS to reboot.

Resolved an issue where setting ports as a port group, then changing one port to wired-auth type, caused the RAS to become unresponsive.

When downgrading from 5.0 to 4.1 (and earlier releases), changes may be required in the 4.1 configuration if the 5.0 configuration had a service profile with last-resort or web-portal access. Specifically, an authentication access rule must be added for last-resort users and the correct VLAN (and other attributes) may need to be set for the last-resort-<ssid>, web-portal-<ssid> special users. Earlier 4.2 versions contain a script that sets the special user attributes and the last-resort access rule on downgrade from 5.0. It is highly recommended in any case to back up the 4.x configuration before upgrading to 5.0.

Resolved an issue where using the ―monitor port counter receive-errors‖ command displays statistics in wrong order.

Firmware Release 5.0.10.3:

Resolved an issue with the RBT-4102 not coming back online if connected to a non-PoE switch and power or reset cycle was initiated to on host RBT-8xxx controller switch.

Based upon the previous resolution, the thin DAP boot-loader number has been incremented, so the new bootloader code will be automatically downloaded to the DAP.

Resolved an issue where the Client MAC address was not flushed from the FDB after a DAP disconnect.

Resolved an issue where corrupted TAPA packets from configured DAPs were causing the RAS to core crash.

Resolved an issue where a DAP is broadcasting a DHCP request to every IP address renewal. If two DHCP servers are on the same segment this could cause a different DHCP server to send a DHCP response. When this happens it will reboot the DAP even if it already received a DHCP acknowledgement from the correct DHCP server (which was used previously).

Resolved an issue where the RAS generated excessive ROGUE_AP_ALERT:rfslave_handle_packet messages, possibly affecting the DAPs to run countermeasures.

Resolved an issue with multiple core crashes on RASs with ―ASSERT‖ errors and DAP loss due to increased traffic spikes in the network.

Firmware Release 5.0.9.3:

Resolved an issue for a performance problem with one of the encryption methods used in the supported access points. Due to a change to the Atheros radio driver code, the WPA/TKIP protocol was executed in software instead of in hardware. This led to a reduction in throughput of approximately 33% for that encryption type. This problem also brought with it a chance of CPU over utilization that could lead to the access point rebooting while under heavy WPA/TKIP traffic load.

Resolved an issue where connection loss occurred between the Intel 3945 Internal Wireless NIC and the non- broadcasting SSID from the RoamAbout Switch system.

Resolved an issue where the RAS reported a ―DAP: Recv Seq Cntr Failure‖ error message from clients using WPA-TKIP authentication, causing some clients to lose wireless connections to the network.
