SUMMARY OF INCIDENTS FIXED BY THE PATCH
---------------------------------------
Patch ID: PHNE_44046
* 3436040 (3436039) In case of a link failover in an aggregated link, the LLT
protocol keeps transmitting the broadcast packets with an old source MAC address.


DETAILS OF INCIDENTS FIXED BY THE PATCH
---------------------------------------
This patch fixes the following Symantec incidents:

Patch ID: PHNE_44046

* 3436040 (Tracking ID: 3436039)

SYMPTOM:
When an aggregated link is configured with the Low Latency Transport
(LLT) protocol using the fast-path mechanism, and a failover happens in this
link, then the LLT continues transmitting the broadcast packets with an old
source MAC address.

DESCRIPTION:
Due to a link failure or some other reason, LLT fails to update the source MAC
address of the link in the broadcast packet header and continues transmitting
the broadcast packets with an old source MAC address.

RESOLUTION:
The LLT source code is modified such that the source MAC address is updated in
the broadcast packet header when the link failover occurs.



INSTALLING THE PATCH
--------------------
Perform the following steps on all the nodes of the cluster:

1) Bring down the VCS stack with the help of corresponding init scripts of the various modules.

2) Unconfigure GAB and LLT modules with:
   # gabconfig -U
   # lltconfig -Uo

3) Unload GAB and LLT modules with:
   # kcmodule gab=unused
   # kcmodule llt=unused

4) Apply the patch with:
   # swinstall -x autoreboot=true -s <patch_directory>  PHNE_44046

5) Start the LLT and GAB modules with the help of init scripts:
   # /sbin/init.d/llt start
   # /sbin/init.d/gab start

6) Start rest of the VCS stack with the help of corresponding init scripts.
