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.

Patch 86222-10 For Rapier Switches and AR800 Series Modular Switching Routers 3
Patch 86222-10 for Software Release 2.2.2
C613-10319-00 REV J
A configuration problem prevented trunking of gigabit ports at 100Mbit
speeds. This issue has been resolved. The A39 gigabit copper uplink
reverted to autonegotiation after a restart, even if it was configured to a
fixed speed. This issue has been resolved. When the port has been
configured for a fixed speed, the mode is now set to MDIX, not MDI.
When an M2 version of the AR020 PRI E1/T1 PIC was installed in a AR040
NSM it was not possible to select the T1 mode of operation regardless of the
jumper setting. This issue has been resolved.
A fatal error occurred when the firewall discarded disallowed multicast
packets. This issue has been resolved.
Features in 86222-08
Patch file details for Patch 86222-08 are listed in Table 3.
Patch 86222-08 includes all issues resolved and enhancements released in
previous patches for Software Release 2.2.2, and the following enhancements:
Tunnel creation failed when attempting to establish a point-to-point tunnel
from an ATR router (tunnel originator) to another vendor’s router. This
issue has been resolved.
When IGMP snooping was enabled, if a member left a group on a port, it
could not re-join the group on that port. This issue has been resolved.
Substantial changes have been made to PIM in more recent code releases.
These have been retrofitted to 2-2-2 in the patch. Note: these changes have
incorporated PCRs 01159 and 01190.
The PPPoE access concentrator did not stop RADIUS accounting when a
PADT termination was received without receiving a proper PPP
termination first. This issue has been resolved.

Features in 86222-07
Patch file details for Patch 86222-07 are listed in Table 4:
Table 4: Patch file details for Patch 86222-07
Patch 86222-07 includes all issues resolved and enhancements released in
previous patches for Software Release 2.2.2, and the following enhancements:
DHCP now correctly handles request messages containing request list
options not supported by the router.
The router would accept TCP sessions with destination address the same as
the subnet broadcast address for one of the router’s interfaces. Firewall-
generated packets destined for a subnet broadcast address on one of the
routers interfaces would cause a fatal error. These issues have been
resolved.
A watchdog timout occurred when the router received an HTTP message
with an over-length header. Normal HTTP requests would also occasionally
cause watchdog timeouts. These issues have been resolved.
The OSPF route filter was not filtering out external routes. This issue has
been resolved.
MD5 Authentication now works correctly with RIP packets.
The SET IP LOCAL command caused a fatal error if the router was
configured with a default route over an L2TP tunnel, because there was no
valid route to the remote IP address of the tunnel. This issue has been
resolved.

Patch 86222-10 for Software Release 2.2.2
C613-10319-00 REV J
Debug messages are no longer generated when a Q.931 Advise of Charge
Notification message is received.
TCP sessions would get stuck in the FINWAIT2 state if the remote host did
not send a FIN message when required. The router now starts a timer when
a TCP session enters the FINWAIT2 state and will automatically close the
session if the timer expires.
The SET IP FILTER command was not correctly handling the ICMPTYPE
and ICMPCODE parameters. This issue has been resolved.
The router will now accept DHCP messages that are greater than or equal
to 576 bytes in size, and reject any message smaller than 576 bytes. This
operation conforms to RFC 1541.
ISAKMP quick mode exchanges are now committed if any traffic is received
over the newly generated SA. This improves stability in very lossy networks
where the commit message may get lost.
ISAKMP debugging caused a fatal error when the debugging mode was set
to ALL and PFS was enabled. This issue has been resolved.
PPPoE interfaces with IDLE set to ON would not retry active discovery
when more data was received if active discovery had previously failed. This
issue has been resolved.
A memory loss occurred when certificates were used by ISAKMP. This issue
has been resolved.
ISAKMP heartbeats are no longer transmitted if the lower layer interface is
down. This stops ISAKMP heartbeats from bringing up links in dial-up
environments.
In some conditions it was possible for ISAKMP packets to be lost and not
retransmitted. Incoming ISAKMP messages are now validated before
stopping retransmission of the previous message.
The COS_DST bit on ARL for L3 interface should be 0x4 (higher priority) for
CPU ports. This has been corrected.

C613-10319-00 REV J
The Trigger Facility was generating a trap with variable { 0 0 }, and was not
documented in the ATI enterprise MIB. This issue has been resolved. The
MIB object triggerLastTriggerActivated ({ enterprises(1) alliedTelesyn(207)
mibObjects(8) brouterMib(4) atrouter(4) modules(4) trigger(53) 1 }) has been
defined, to record the trigger number of the last trigger activated, and this
variable is now transmitted in the trigger activation trap triggerTrap.
In a Rapier G6, fitted with a fibre uplink module with all ports active,
switching traffic between port 1 and the uplink caused the traffic flow to
cease after a period of time depending on the volume of traffic. This issue
has been resolved.
The Rapier did not include the message age of the received BDPU message
in the message age of the BDPU it transmitted. Also, the message age of the
message transmitted BDPU could be less than that of the received BDPU,
which contravenes IEEE 802.3d. This issue has been resolved.
Reception of incorrectly tagged packets was causing corruption of the ARL
table, eventually causing the switch to lock up. This issue has been resolved.
Tagged packets with invalid VLAN identifiers are now discarded. The
INFILTERING parameter of the SET SWITCH PORT command now
defaults to ON.
Flow control performance has been improved.
The IPsec SA ID now wraps correctly at the 16 bit (ID = 65535) boundary.
The ID is also checked to verify that it is free before it is used.
If PPPoE AC services were not deleted in the same order they were added,
the DELETE command would return an “ operation successful” message
but the service would still appear in the output of the SHOW PPP PPPOE
command. This issued has been resolved.
The CREATE CONFIG command did not include all required L3FILTER
parameters in the generated script file.
The L3 table on the Rapier G6 is now cleared when a switch port goes down
to ensure the L3 and ARP tables are consistent.

Patch file details for Patch 86222-06 are listed in Table 5.
Patch 86222-06 includes all issues resolved and enhancements released in
previous patches for Software Release 2.2.2, and the following enhancements:
The power supply voltages of the base board PHYs on a Rapier G6 are
controlled by a PHY register value, which was incorrectly set. This issue has
been resolved.
In PIM Dense Mode, if a data stream started before PIM hello messages
were exchanged, the receiver did not get the data stream. This issue has
been resolved.
The Rapier G6 base ports sometimes experienced spurious link up or link
down events. This issue has been resolved.

C613-10319-00 REV J
A39 copper uplink modules in the Rapier G6 sometimes experienced
spurious link up or link down events. This issue has been resolved.
The enterprise MIB now supports objects for power supply monitoring.
Certificates containing GeneralisedTime with the year in YYYY format are
now parsed correctly. The keyUsage field of certificates is now parsed
correctly when only one byte has been specified. The CRL update time is now
displayed correctly in hours. If the username and password parameters are
present the location parameter must be present and appear before the
username and password parameters. Certificates with signatures of 257 bytes
are now correctly parsed. Certificates added from a configuration script are
now processed correctly.
A fatal error occurred if an IPv6 interface was deleted while packets were
being transmitted. The number of current interfaces was not being updated
correctly when a new IPv6 interface was added. As a result, after multiple
additions and deletions, no more IPv6 interfaces could be added. These
issues have been resolved.
The CREATE CONFIG command now adds PKI certificates to the script in
the same order that they were originally added to the certificate database.
PKI certificates are now periodically checked (once per hour) to verify that
they are still valid.
IPCOMP SA’s which have the reserved CPI “3” are no longer deleted by
ISAKMP delete messages.
When a VLAN was created and then destroyed on the G6 or G6F, the
VTABLE was corrupted. This has been fixed.
DHCP failed to send request messages when it was in a rebinding or
renewing state. This issue has been resolved.
In some extreme traffic conditions the switch could lock up, preventing
switching of any traffic. This issue has been resolved.

Repeated addition and deletion of an address with the VALID parameter set
to or from an IPV6 interface caused a fatal error. This issue has been
corrected. The VALID parameter specifies the life of the address, and
defaults to INFINITE. The address is deleted when the lifetime expires. The
PREF parameter specifies the time that the address is the preferred address
of the interface, and defaults to INFINITE. PREF must be less than or equal
to VALID. IPV6 now checks and ensures that if either PREF or VALID is
specified, PREF is less than or equal to VALID. When an address is deleted
the timers are now correctly cleared.
IP sometimes passed the wrong port number to PIM, causing PIM to
process the wrong port number in its routing table. This issued has been
resolved.
