Customer Release Notes

Firmware Release 6.0.7.2:

Upgrading to RAS Version 6.0 and Certificate Issue: Customers may experience issues with Certificates or Private keys installed on RASes after upgrading to newer 5.0 and 6.0 releases. Error messages relating to this issue may include the following:

-HTTPD Aug 14 16:32:13.648823 ERROR HTTPD: SSL connection failure (bad cert?);

-Admin client 145.36.245.51 EAP Aug 14 16:32:14.110502 ERROR EAP_STORE_ERR: No EAP key pair. Cannot do PEAP

Affected services may include SSH, Web-portal, PEAP-offload, WebView, and RASM administrative access and/or Domain Security.

You can prevent this issue by generating new private keys and any related Certificates prior to upgrading to a newer version of the RAS. Third party Certificates should be exempt from this issue provided a new private key was explicitly generated before the CSR request generation. If you are unsure whether a new private key was generated before the initial CSR, the best course of action may be to request a replacement certificate from your provider using a new private key.

Customers encountering this issue can follow the same process to restore normal operation. Details on generating private keys, self-signed Certificates and certificate requests can be found in the Enterasys RoamAbout Mobility System Software Configuration Guide.

The set ap <apnum> boot-configuration switch switch-ip cannot be set at the same time as set ap <apnum> boot-configuration switch name <switch-name> dns <ip addr>. The commands overwrite each other when used.

The Web-portal ACL does not work with IPv6 traffic. IPv6 clients cannot authenticate using Web Portal unless the clients also run IPv4. This issue affects Web-Portal authentication only. The other authentication types (802.1X, MAC, and Last Resort) can be used with IPv6 clients.

The LED radio designation for the RBT-4102-thin is not the same as the RBT-4102 in a standalone mode. In the thin mode, the LED labeled ―1‖ should be associated with the B/G band, and LED ―2‖ is associated with the ―A‖ radio band.

In the RAS User Guides and Configuration manuals, the syntax for the ‗set dap boot-ip‘, ‗set dap boot-switch‘, and ‗set dap boot-vlan‘ commands is incorrect. The actual commands in the RAS firmware version 5.0 are ‗set dap boot-configuration ip‘, ‗set dap boot-configuration switch‘, and ‗set dap boot-configuration vlan‘. In 6.0.x.x, these commands are ‗set ap boot-configuration ip‘, ‗set ap boot-configuration switch‘, and ‗set ap boot- configuration vlan‘.

There is an LED issue with the RBT-82x0 switches, where both ports could show an incorrect connection status after a device reboot when there is no cable attached. This does not affect the performance for either port in any way.

Router redundancy protocol on intermediary devices between RBT-8xx0 switches in a Mobility Domain can interfere with communication among the switches. The workaround to this issue is to set the FDB timer (default 300 seconds) and the ARP timer (default 1200 seconds) to the same values on the RASes. Enterasys Networks recommends using 300 seconds as the value for both timers.

Mixing Autonegotiation with full-duplex mode on a link causes slow throughput and can cause an RBT-8xx0 port to stop forwarding. The slow throughput occurs because the side that is configured for autonegotiation falls back to half-duplex. A stream of large packets sent to an RBT-8xx0 port in such a configuration can cause forwarding on the link to stop.

The RAS allows ** to be specified as a MAC address glob, but this is invalid for MAC globs.

There is an open issue when deploying the command ―set port disable 1‖ does not disable the port on the RBT-8100.

The RBT-8400 mishandles fragmented packets from the XSR router due to a limitation in the network processor.

Clients using the RBTBG/RBTBJ wireless client card with the RBTBX-PC wireless PCI NIC adapter have experienced extended periods of traffic loss (up to 33% ping loss over a ten-minute time span).

The external antenna names for the RBT-1602 AP have not been converted to the Enterasys specific naming convention. Note: Refer to the Tech Tip on page 22 for important information about configuring antenna types for an RBT-1602 Access Point.
