NOTE: To avoid conflicts with internal RAS VLAN numbering schemes, it is strongly advised to use VLAN IDs
less than 3520 on RBT-8xxx systems that are upgrading from MSS version 6.0 to 7.0. Failure to do so
will result in a loss of configuration data.
NOTE: RoamAbout Wireless Switch Firmware version 5.0.9.2 and greater supports the RBT-8210, the small
form factor switch that replaces the larger RBT-8200. The RBT-8210 uses the RBT-8200 firmware and
commands. The RBT-8210 prompt displays as RBT-8200.
NOTE: If you are using a 4.x firmware image/software, Enterasys recommends that you upgrade the
RoamAbout Switch Manager (RASM) to firmware version 5.0.12.2 BEFORE upgrading your RBT-8xx0
wireless switches to firmware version 5.0.12.2. Please refer to the Upgrading the RBT8xxx switches
section of this release note for more information.
NOTE: If you are upgrading a pre-existing RBT-4102 or RBT-4102-EU model Access Point from 4.1.4 or earlier,
please read the instructions listed in the Firmware Release 4.1.5.0 section of the Firmware Changes
and Enhancements section of the RoamAbout Switch Manager (RASM) 6.2.2.4 Release Notes.
NOTE: RoamAbout Wireless Switch Firmware version 6.0.4.2 and greater replaces the term „DAP‟ with „AP‟.

IGMP snooping is not supported with local switching.
Locally Switched AP‘s can support a total of 25 ACL rules, including both inbound and outbound
ACLs.
For Wireless bridging, here are some best practice guidelines:
oWhen connecting a Mesh Portal to the network, use only ethernet port 1 on the AP.
oBecause all AP CPU cycles are devoted to bridging, make other arrangements for service
coverage in the bridge area as the endpoints cannot provide other wireless services.
oA single radio must be devoted to maintaining the bridge.

Note: You must upgrade to RAS Version 5.0 or later before upgrading to RAS Version 7.0.
Preparing the RAS for the Upgrade
Note: The following upgrade procedures refer to all RBT-8xx0 switches.
Caution!
Save the configuration, and then create a backup of your RAS files before you upgrade the switch.
Enterasys Networks recommends that you make a backup of the switch, before you install the upgrade. If
an error occurs during the upgrade, you can restore your switch to its previous state. If you later decide to
downgrade the switch, commands with newer syntax in future RAS versions may not be converted
correctly.
1. Use the following command to save the configuration. Unsaved changes will be lost during the upgrade
procedure:
RBT-8xx0# save config [filename]
2. The following command should be used to back up the switch‘s files:
RBT-8xx0# backup system [tftp://ip-addr/]filename [all | critical]
3. To restore a switch that has been backed up, use the following command:
RBT-8xx0# restore system [tftp://ip-addr/]filename [all | critical] [force]
The ―Upgrade Scenario‖ listed below shows an example use of the backup command. For more information about
these commands, see the ―Backing Up and Restoring the System‖ section in the ―Managing System Files‖
chapter of the RoamAbout Mobility System Software Configuration Guide.
Note: If you have made configuration changes but have not saved the changes, use the save config
command to save the changes, before you back up the switch.
If the RAS is running an earlier version of firmware, use the copy tftp command to copy files from the switch onto
a TFTP server.
Upgrading an Individual Switch Using the CLI:
1. Save the configuration, using the save configuration command.
2. Back up the switch, using the backup system command.

3. Copy the new system image onto a TFTP server.
For example, login to http://www.enterasys.com/download/ using a web browser on your TFTP server and
download the image onto the server.
4. Copy the new system image file from the TFTP server into a boot partition in the switch‘s nonvolatile
storage. You can copy the image file only into the boot partition that was not used for the most recent
restart. For example, if the currently running image was booted from partition 0, you can copy the new
image only into partition 1.
5. Set the boot partition to the one with the upgrade image for the next restart.
a. To verify that the new image file is installed, type show boot.
6. Reboot the software.
a. To restart a RAS and reboot the software, type the following command:
RBT-8xx0# reset system [force]
After resetting the RAS, the switch boots using the new image. The RAS also sends the AP version of the
new boot image to the configured APs and restarts the APs. After an AP restarts, it checks the version of
the new AP boot image to make sure the boot image is newer than the boot image currently installed on
the AP. If the boot image is newer, the AP completes installation of its new boot image by copying the
boot image into the AP‘s flash memory, which takes about 30 seconds, then restarts again. The upgrade
of the AP is complete after the second restart.
Upgrade Scenario:
To upgrade an RBT-8xx0 switch from one RAS version to another, type commands such as the following.
Note: This upgrade scenario uses the firmware image file 6.0.7.2 to show the download features. Please
follow these procedures for any of the 4.0.x, 4.1.x, 4.2.x, and 5.0.x firmware images.
Note: This example copies the image file into boot partition 1. On your switch, copy the image file into
the boot partition not used for the last restart. For example, if the switch booted from boot partition 1, copy
the new image into boot partition 0. To see boot partition information, type the show boot command.
RBT-8200# save config success: configuration saved.
RBT-8200# backup system tftp:/[ip-addr]/sysa_bak success: sent 28263 bytes in 0.324 seconds [ 87231

Resolved an issue with the command "show ap global". When the command was run on a Mobility Domain with
access points configured in a redundant mode, only the APs configured for High Bias on that RAS appeared.
Firmware Release 6.0.6.1:
Resolved an issue where the filter-ID was only working with colons not semicolons.
Resolved an issue where the ETS logo in Webview screens showed the outdated image.
Resolved an issue where an IP Checksum Error caused slow network performance.

Resolved an issue where the user glob for accounting could not be set to ** in the CLI.
Resolved an issue where GuestPass users using the Web portal page timed out before reaching the default
802.1X time.
Resolved an issue where the Access Point strips the VLAN header from a tagged packet before the Tunnel
encapsulation from the AP to the RAS. This occurs with Direct Path Forwarding (Local Switching) enabled on
the Access Point.
Resolved an issue where the installation of a CA certificate was not recognized by the RAS if the certificate
chain were included in the CA certificate file.
Resolved an issue where the RBT-4102-EU AP would crash after receiving 6 or more DNS requests.
Resolved an issue where client roaming was slow or failed altogether under heavy load on the Access Point.
The TXOP limit is sometimes included in AC Voice, and sometimes it does not appear (but the length of the
WMM element is the same). In addition, some management frames are two bytes smaller than what they specify
because the radio driver appears to be stripping 2 bytes off management frames in certain situations.
Firmware Release 6.0.5.1:
The number of packets in the DNS packet queue increased from 3 to 8.

Firmware Release 6.0.5.1:
The 6.0.5.1 release now supports 25 ACL rules (ACEs) per ACL, total of inbound and outbound, to be mapped
to the user if the AP has Direct Path Forwarding (Local Switching) enabled. There can be more than one ACL,
with 25 ACEs, applied to multiple users on the AP. If an ACL with 26 or more rules is mapped to the user with
Local Switching enabled, the users in the network will not connect or authenticate to that wireless network.
Enterasys Networks recommends creating separate ACL profiles to be used for those users who are
authenticated into the Local Switching VLAN profile.
Resolved an issue with the Web Authentication page and login slowness due to the memory buffer for non-
parsable http requests not being freed.
Resolved a memory leak issue in the TCP machine that caused Netsys crashes. The memory was not freed in
cases where the client attempts to close the tcp connection from its end but we still have some data to send out.
Resolved an issue where certain wireless IP phones would not connect to the AP1002, RBT3K-AG, or
RBT-4102.
Resolved an issue where Radius calling-station-id not sent by the Web-portal functionality.
Resolved an issue where an NMAP scan would cause the web portal page to no longer function.
Resolved an issue where a WebView error was seen for the browser URL reference icon.
Resolved an issue where ACL rules were not applied to a Locally switched user.
Resolved an issue where certain fdb errors were seen on a Mesh AP after it was reset.
Resolved an issue when the login WebAAA page displayed a partial logo or title header.
Resolved an issue where a Bonded Authenticated user would not get an IP address using the TKIP cipher.
Resolved an open endian issue where an ICMP ACL rule (ACE), with either the source or destination IP address
fields and masks configured, will not get applied to an authenticated user with Direct Path Forwarding (Local
Switching) enabled.
Resolved an issue where the ACL Mapping with Local Switching fails after adding the 17th ACL rule.
Firmware Release 6.0.4.4:
Resolved an issue where a bit on the non-mesh supported Access Points could be randomly set, causing the
APs to reset several times.
Resolved an issue where an external antenna attached to the TRPZ-MP-422 Access Point was not transmitting
the configured power.
Resolved an issue for the RBT-8400 where system generated core crash files were truncated and unreadable.
Firmware Release 6.0.4.2:
Added support for the TRPZ-MP-620 Outdoor Access Point. Direct Path Forwarding (Local Switching), Mesh
Services, and Wireless Bridging are only supported on the TRPZ-MP-620 and TRPX-MP-422 Access Points.
The RBT-8400 image is smaller than previous releases due to a shared library format introduced in the 6.0
firmware. Statically linked executables, which called to individual library functions, were replaced with run-time
calls, reducing the total number of individual library routines to be opened, and reducing the overall size of the
firmware required to operate the network switch. This format also increases the amount of memory available for
data transfer and table maintenance.
Resolved the issue where the Static IP configuration and deployment for the AP4102 and AP3000 did not
remain persistent with the AP upon reboot.
Resolved the erroneous message error printed to the CLI when the RBT-8400 reboots with 5.0.12.2:
Bootloader upgrade 5.0.x to 5.0.x needed. (x could be any number)
cp: /boot0/bload: No space left on device
Resolved an issue where the TRPZ-MP-422 Access Point image does not load with the 6.0.x code.
Resolved an issue where the configured APs in a network plan would crash upon RAS firmware upgrade due to
a DNS update entry on the RAS.
Resolved an issue where the Radius CLASS attribute was not sent with stop packets.
Resolved an issue where the RAS spoofed a DNS reply with a 169.254.x.x if the DNS server took more than 3
seconds to respond. Certain Linux and Vista users will drop this packet causing everything to fail
Resolved an issue where the configured APs would crash with various exception messages, including TLB data
miss and sigtrap.

and corrupting the header of the following buffer.
Resolved an issue where the RBT-8400 CPU utilization increases due to a DHCP request packet looping issue
with the port- trunk functionality.
Resolved an ASSERT and exception DAP crash due to a corrupted link header when the DAP is rebooting.
This issue occurred when a packet entered the AP through the Ethernet MAC, and the Access Point stored this
packet in memory spot in which the operational code needed zeroed out.
Resolved an issue where the RBT-1002 Ethernet port would transition to half-duplex under heavy traffic load
(approximately 25 Mbps throughput).
Resolved an issue where the WebAAA login page would not resolve due to a certificate failure on a client using
the Vista OS and Microsoft Internet Explorer version 7. The workaround is for the client to open the Internet
Explorer browser as ―Administrator‖ and accept the WebAAA certificate.
Resolved an issue where a client using the Vista OS and Microsoft IE 7 failed to get the WebAAA login page
when the Common Name in the RAS Web certificate equals ‗*.<domain>.com‘.
Resolved an issue where the radio information was not displayed after issuing the ―show sessions‖ command.
Resolved an issue where the RBT-8400 locked-up due to a processor losing entries in the FDB, and over time,

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.

Firmware Release 4.0.21.0:
Resolved an issue where ACLs were not properly assigned to users due to the incorrect parsing of the
Enterasys filter ID string (Enterasys:version=1:policy=<policy name>) returned from a RADIUS server.
The default MAC authentication RADIUS password has been changed from ‗nopassword‘ to ‗NOPASSWORD‘.
Firmware Release 4.0.20.0:
Added support for the RBT-1602 Access Point.
Increased the limit of local mac authenticated users from 75 to 2400 (this fix was originally listed in the 4.0.18.0
Firmware Release section, but the implementation did not occur until this 4.0.20.0 release).
Resolved the issue where a WebAAA user would not be redirected to a web page if the proxy setting were
enabled.
Firmware Release 4.0.18.0:
MTU for Tunneled traffic was too long —Previous versions of MSS required an IP Path MTU (PMTU) of
1484 bytes for tunneled traffic, and used a non-standard implementation of IP Fragmentation to transport IP
datagrams larger than that PMTU. Because of the non-standard fragmentation, tunnel IP datagrams could be
dropped by devices attempting to validate packets for proper formatting. The current MSS version fixes this
issue. IP Fragmentation is supported in accordance with RFC 2003. This change allows third-party devices in
the communication path to validate properly fragmented tunnel IP datagrams. In addition, the maximum packet
size is smaller. In the current MSS version, the PMTU requirement has been reduced to 1384 bytes, to allow
devices along the communication path to encapsulate further the tunnel packets without introducing additional
fragmentation.
Resolved an issue where associated clients (to clear SSID) could access WebView and changing system
configurations.
Firmware Release 4.0.16.0:
Added support for the RBT-8400 RAS and the RBT-1002 Access Point.
Resolved an issue where MAC addresses would be dropped from the Filter Database without the session timing
out (fdb hashing error in the database).
Resolved an issue where the RBT-8100 would have a core dump after trying to save a configuration file with a
name longer than 16 characters.
Resolved an issue where a user would not get a DHCP address using WebAAA and the internal DHCP server
on the RBT-8100.
Resolved the password recovery method, where the ―Esc‖ prompt during the RBT-8100 boot-up cycle appeared
too late in the boot-up cycle.
Resolved an issue where the Service Profile would only allow a 16-character name.
Firmware Release 4.0.7.0:

KNOWN RESTRICTIONS AND LIMITATIONS:
Firmware Release 7.0.7.3:
802.11n adapter incompatibility with Spectralink Voice Protocol (SVP) enabled service profiles.
Description —Some 802.11n wireless adapters may experience packet loss on wireless services with the
Spectralink Voice Protocol enabled. This problem only exists when using the TRPZ-MP-432 with frame
aggregation enabled.
Workaround —When using SVP on the TRPZ-MP-432 disable frame aggregation.
The aggregate throughput exceeds the bandwidth limit of the SSID.
Description —Per SSID max-bw is only enforced within the scope of one radio. Therefore, if you configure
multiple SSIDs per radio and configure bandwidth management on the SSIDs, you can exceed the bandwidth for
each SSID.
Workaround —Configure bandwidth management on a per radio basis. The limits for service-profile max-bw
and service-profile cac-session are enforced independently on each radio.
Upgrading from MSS 6.0 to MSS 7.0 changes the antenna location from Indoor to Outdoor on the AP.
Description —If an AP is configured with the antenna location as Indoor and you upgrade the
MSS version from 6.0 to 7.0, the antenna location changes to Outdoor.
Workaround —Reconfigure the antenna with the proper location after upgrading the MSS version.
Changes to the DTD cause incompatibility with cluster configuration.
Description —MSS Cluster Configuration relies on configuration options being consistent between cluster
members. Changes to configuration options introduced between releases can result in synchronization problems
between cluster members.
Workaround —All RASs in a cluster configuration should have the same version of MSS.
Using the quickstart command on the TRPZ-MX-2800 incorrectly sets VLAN tag ID.
Description —When configuring the TRPZ-MX-2800 using the quickstart command, it is possible to configure
an invalid VLAN tag value for the default management VLAN.
Workaround —After completing the quickstart configuration, create a new VLAN with the correct VLAN tag.
Using the auto-ap feature does not allow load balancing on individual radios.
Description —When using the auto-ap feature, it is not possible to set all of the AP attributes. Per AP load
balancing control is not supported on auto-ap. The system global settings for load balancing applies to all
auto-aps.
Workaround —If you must configure a load-balance group for a specific AP, configure the AP as a regular AP.
Auto-aps do not behave correctly on cluster seed when the maximum number of APs are configured.
Description —When a cluster seed RBT-8xxx boots an auto-ap, it checks the seed configuration on the RBT-
8xxx to determine if the cluster can support any additional AP‘s. If the system is already configured with the
maximum number of APs allowed, new auto-aps do not operate correctly.
Workaround —Reduce the number of configured APs in the cluster configuration.
Voice handsets can be sensitive to changes on an in-service SSID.
Description —Particular voice handsets are sensitive to changes made to an in-service SSID. This can result in
the handset operating with stale connection information.
Workaround —When using affected handsets, disable the Service Profile prior to making any configuration
changes.
Some RAS controllers show an incorrect CPU load.
Description —RAS controllers show an erroneous CPU load of 100% in the command line interface. This will
be fixed in the next version of MSS.
Workaround —None.

F0615-O
Firmware Release 7.0.4.3:
Using the auto-ap feature does not allow load-balancing on individual radios.
Description —When using the auto-ap feature, it is not possible to set all of the AP attributes.
Per AP load-balancing control is not supported on auto-ap. The system global settings for
load-balancing apply to all auto-aps.
Workaround —If you must configure a load-balance group for a specific AP, configure the AP as
a regular AP.
Using telnet over a WAN link may affect the telnet session.
Description —When using telnet to manage a RAS over a high-latency WAN link, it is possible
for the telnet session to stop responding.
Workaround —Restart the telnet session.
Auto-aps do not behave correctly on cluster seed when the maximum number of APs is
configured.
Description —When a cluster seed RAS boots an auto-ap, it checks the seed configuration on the RAS to
determine if the cluster can support any additional APs. If the system is already configured
with the maximum number of APs allowed, new auto-aps do not operate correctly.
Workaround —Reduce the number of configured APs in the cluster configuration.
Voice handsets can be sensitive to changes on an in-service SSID.
Description —Particular voice handsets are sensitive to changes made to an in-service SSID.
This can result in the handset operating with stale connection information.
Workaround —When using affected handsets, disable the Service Profile prior to making any
configuration changes.
The time and date do not synchronize with an NTP server, if the NTP client on the RAS
is enabled before the NTP service is started on the server.
Firmware Release 7.0.3.7:
Description —If you reload a switch configuration with cluster mode turned on, RASM cannot determine which
RoamAbout switch is the active seed in the cluster configuration. (53952)
Workaround —Disable cluster mode and then re-enable it. Normal operation resumes on the network.
Using the auto-ap feature does not allow load-balancing on individual radios. (53331)
Description —When using the auto-ap feature, it is not possible to set all of the AP attributes. Per AP load-
balancing control is not supported on auto-ap. The system global settings for load-balancing applies to all auto-
aps. (53331)
Workaround —If you must configure a load-balance group for a specific AP, configure the AP as a regular AP.
Using telnet over a WAN link may affect the telnet session. (52853)
Description —When using telnet to manage a RoamAbout switch over a high-latency WAN link, it is possible
for the telnet session to stop responding. (52853)
Workaround —Restart the telnet session.
Auto-aps do not behave correctly on cluster seed when the maximum number of APs is configured. (52633)
Description —When a cluster seed RoamAbout switch boots an auto-ap, it checks the seed configuration on
the RoamAbout switch to determine if the cluster can support any additional APs. If the system is already
configured with the maximum number of APs allowed, new auto-aps do not operate correctly.
Workaround —Reduce the number of configured APs in the cluster configuration.
CAPWAP data plane UDP port changed from 5001 to 5247. (53029)
Description —The UDP port for CAPWAP data packets has changed from 5001 to 5247 to comply with the
updated CAPWAP specification. You may experience problems with roaming VLANs between RoamAbout
switches with MSS Version 7.0 and RoamAbout switches with earlier versions of MSS.
Workaround —If your network configuration requires tunnled VLANs, be sure that all RoamAbout switches on
the network are configured with the same version of MSS.
Using the active-scan feature triggers packet loss on legacy APs with older Intel wireless adaptors. (50901)
Description —When using active-scan on legacy APs with the Intel 2915 wireless adaptor, a station may
experience some level of packet loss. (50901)
Workaround —Disable active-scan on any legacy APs supporting older Intel clients.
