Patch Release Note
Patch 86222-10 for Software Release 2.2.2
C613-10319-00 REV J
Some switch chip register settings have been optimised to improve the
provision of CoS with the newer revision of switching silicon.
Features in 86222-09
Patch file details for Patch 86222-09 are listed in Table 2.
Patch 86222-09 includes all issues resolved and enhancements released in
previous patches for Software Release 2.2.2, and the following enhancements:
A new feature, STP forwarding, has been added. STP forwarding can be
enabled and disabled using the commands:
ENABLE SWI STPFORWARD
DISABLE SWI STPFORWARD
When STP forwarding is enabled, all STP forwarding is ignored and all
BDPUs received on a port are forwarded on all other ports.
The switch now delays sending link traps immediately after a restart to give
the link to the trap host time to come up. A similar change has been made
for the cold start trap. After a 10s delay, all interfaces which are UP have a
link trap generated for them. After that, link traps are sent as normal.
Processing invalid UDP packets caused a memory leak. This issue has been
resolved. Additional debugging facilities were added.
The default setting for the switch port parameter INFILTERING is now OFF,
as specified in IEEE802.1Q. A VLAN will still reject these packets if they are
not from valid VLAN member ports.
The IGMP snooping forwarding process now correctly selects outgoing
ports when DVMRP is managing the multicast routing information.
