RHBA-2012:1175 - Bug Fix Advisory

Topic

Updated lldpad packages that fix a bug are now available for Red Hat Enterprise
Linux 6.

Description

The lldpad packages provide the Linux user space daemon and configuration tool
for Intel's Link Layer Discovery Protocol (LLDP) agent with Enhanced Ethernet
support.

This update fixes the following bug:

• Previously, an error in the DCBX (Data Center Bridging Exchange) version

selection logic could cause LLDPDUs (Link Layer Discovery Protocol Data Units)
to be not encoded in the TLV (Type-Length Value) format during the transition
from IEEE DCBX to the legacy DCBX mode. Consequently, link flaps, a delay, or a
failure in synchronizing up DCBX between the host and a peer device could occur.
In the case of booting from a remote FCoE (Fibre-Channel Over Ethernet) LUN
(Logical Unit Number), this bug could result in a failure to boot. This update
fixes the bug and TLV is now always used in the described scenario. (BZ#844415)

All users of lldpad are advised to upgrade to these updated packages, which fix
this bug.
