LCOS LX improvements 6.14.0070 RU1
Bugfixes / improvements
In a scenario with dynamic VLAN, the PCP and DEI bits of the VLAN header
were incorrectly interpreted as part of the VLAN ID when sending a frame
in the direction of the wireless LAN. If these bits were not equal to 0, this
resulted in an invalid VLAN ID, which meant that the dynamic VLAN had no
function in this case.

Due to an error in the dynamic VLAN, communication within tagged VLANs via
a WDS connection was not possible. The untagged VLAN on WDS connections
was not affected.

As of LCOS LX 6.12, uploading several wireless clients at the same time could
result in a heavily increased channel load in the 2.4 and 5 GHz bands. This
resulted in lower data throughput and high packet losses.

In a scenario with multiple access points, if access point A received a packet
from a wireless client that was connected to access point B, access point A
registered the connection source of the wireless client as Ethernet and stored
the MAC address in its forwarding database. Incoming packets from the
Ethernet with the wireless client’s MAC address as the destination were then
discarded. If the wireless client then switched from access point B to access
point A (roaming), the entry in the database with the connection source
Ethernet remained in place. As a result, the wireless client was unable to
communicate via Ethernet until the entry in the forwarding database expired
(180 seconds).

In large scenarios, the use of Dynamic VLAN via 802.1X or LEPS could lead to
sudden restarts of the access points.

A security vulnerability in the SSH protocol has been fixed (‘Terrapin’
vulnerability / CVE-2023-48795)
