Caveats
•
CSCeb10911—Linktest reports higher RSSI readings for the remote site.
There is no workaround for this problem.
•
CSCeb12740—The virtual ratio connection cannot be made after the station role is changed.
After you change the station role of two bridges while the link is active, the radios get associated
but the virtual radio interfaces do not function.
but the virtual radio interfaces do not function.
Workaround: After changing the station roles, you must restart both root and non-root bridges using the
browser interface (System Software > System Configuration > Restart) or the CLI reload command.

•
CSCeb14603—Telnet session locks up under heavy traffic.
There is no workaround for this problem.
•
CSCeb15923—Radio firmware recovery does not work reliably.
There is no workaround for this problem.
•
CSCeb17296—Clear dot client command does not work with traffic being passed.
When traffic is being passed through the bridges at around 30 to 40 percent CPU utilization, the CLI
clear dot client H.H.H command does not clear the counters on the non-root bridge even though
the association did clear.

CSCea77473—HTTP software upgrade with Netscape version 7.x intermittently fails.
When you are upgrading software with Netscape version 7.x, the Web interface cascades through all open

CSCed27956
A vulnerability in the Transmission Control Protocol (TCP) specification (RFC793) has been
discovered by an external researcher. The successful exploitation enables an adversary to reset any
established TCP connection in a much shorter time than was previously discussed publicly.
Depending on the application, the connection may get automatically re-established. In other cases,
a user will have to repeat the action (for example, open a new Telnet or SSH session). Depending
upon the attacked protocol, a successful attack may have additional consequences beyond
terminated connection which must be considered. This attack vector is only applicable to the
sessions which are terminating on a device (such as a router, switch, or computer) and not to the
sessions that are only passing through the device (for example, transit traffic that is being routed by
a router). In addition, this attack vector does not directly compromise data integrity or
confidentiality.
