PCR: 31009  
Module: HTTP  
Level: 3  
The server string was not copied correctly into an HTTP file request when  
loading information from the configuration script. This issue has been  
resolved.  
PCR: 31064  
Module: SWI  
Level: 2  
When 10/100 copper ports were disabled with the DISABLE SWITCH  
PORT command, their link state was still UP. This issue has been resolved.  
PCR: 31072  
Module: SWI  
Level: 3  
If the DISABLE SWITCH PORT command appeared in the configuration  
script, an interface could come up even though ifAdminStatus was set to  
‘down’. This issue has been resolved.  
PCR: 31084  
Module: IPV6  
Level: 2  
A fatal error sometimes occurred because of incorrect responses to  
Neighbour Solicitation messages. This issue has been resolved.  
PCR: 31093  
Module: SWI  
Level: 1  
If a switch port was disabled on a switch running STP, traffic was sometimes  
not passed through that port after it was re-enabled. This issue has been  
resolved.  
PCR: 31096  
Module: FFS  
Level: 3  
The SHOW FILE command caused an error when the displayed file had a  
duplicate entry due to file size mismatch. This issue has been resolved. An  
error message is now logged when the SHOW FILE command detects a  
duplicate file. The first FFS file will be deleted when a duplicate exists.  
PCR: 31098  
Module: DHCP  
Level: 3  
Static DHCP address ranges were not reclaimed if the Reclaim operation was  
interrupted by the interface going down. This issue has been resolved.  
PCR: 31100  
Module: L2TP  
Level: 3  
An error occurred in L2TP when call names consisted of numeric characters  
only. This issue has been resolved. The ADD L2TP CALL command now  
only accepts call names that contain at least one alphabetic character.  
PCR: 31119  
Module: LOG  
Level: 2  
The maximum value that the MESSAGES parameter accepted for the  
CREATE LOG OUTPUT command was different from the value that could  
be set with the SET LOG OUTPUT command. The DESTROY LOG  
OUTPUT command did not release the NVS memory that was reserved for  
the output. These issues have been resolved.  
PCR: 31132  
Module: DHCP  
Level: 2  
The DHCP server did not take any action when it received a DHCP decline  
packet. This was because the device only checked the ciaddr field in the  
packet, and not the RequestedIPAddress option. This issue has been resolved.

ADD IGMPSNOOPING ROUTERADDRESS  
Patch Release Note  
PCR: 31133  
Module: IPG  
This PCR introduces an enhancement that extends an issue that was  
resolved in PCR 03890, in which switch port entries are only created for  
special router multicast addresses. It is now possible to specify reserved  
multicast addresses that will be treated as multicast packets from routers.  
Use the following commands to configure this feature.  
ADD IGMPSNOOPING ROUTERADDRESS  
Syntax ADD IGMPSNOOPING ROUTERADDRESS=ipaddr[,...]  
Description  
where:  
ipaddr is a reserved IP multicast address in dotted decimal notation.  
This command adds reserved IP multicast addresses to the list of router  
multicast addresses. The IP address specified must be within the range  
224.0.0.1 to 224.0.0.255. This command is only valid if the IGMP snooping  
router mode is set to IP with the SET IGMPSNOOPING ROUTERMODE  
command.  
SET IGMPSNOOPING ROUTERMODE  
Syntax SET IGMPSNOOPING ROUTERMODE=  
{ALL|DEFAULT|IP|MULTICASTROUTER|NONE}  
Description  
This command sets the mode of operation for IGMP Snooping.  
If ALL is specified, all reserved multicast addresses (i.e. 2240.0.1 to  
224.0.0.255) are treated as router multicast addresses.  
If DEFAULT is specified, the following addresses are treated as router  
multicast addresses:  
IGMP Query: 224.0.0.1  
All routers on this subnet: 224.0.0.2  
DVMRP Routers: 224.0.0.4  
OSPFIGP all routers: 224.0.0.5  
OSPFIGP designated routers: 224.0.0.6  
RIP2 routers: 224.0.0.9  
All PIM routers: 224.0.0.13  
All CBT routers: 224.0.0.15  
If IP is specified, addresses that are treated as router multicast addresses are  
specified with the ADD/DELETE IGMPSNOOPING ROUTERADDRESS  
command. In this mode, the switch will retain previous addresses that have  
already been specified.  
If MULTICAST is specified, the following addresses are treated as router  
multicast addresses:  
DVMRP Routers: 224.0.0.4  
All PIM routers: 224.0.0.13  
If NONE is specified, no router ports are created.

DELETE IGMPSNOOPING ROUTERADDRESS  
Syntax DELETE IGMPSNOOPING ROUTERADDRESS=ipaddr[,...]  
where  
ipaddr is a reserved IP multicast address in dotted decimal notation.  
Description This command deletes reserved IP multicast addresses from the list of router  
multicast addresses. The IP address specified must be within the range  
224.0.0.1 to 224.0.0.255. This command is only valid if the IGMP snooping  
router mode is set to IP with the SET IGMPSNOOPING ROUTERMODE  
command.  
SHOW IGMPSNOOPING ROUTERADDRESS  
Syntax SHOW IGMPSNOOPING ROUTERADDRESS  
Description This command displays information about the list of configured IP multicast  
router addresses currently configured on the switch (Figure 1).

PCR: 31134  
Module: RSTP  
Level: 2  
Bridges transmitted BPDUs at the rate specified by the local helloTime value  
when they were not the root bridge. This is the behaviour specified in  
802.1w-2001. This behaviour can cause instability in the spanning tree when  
bridges are configured with different helloTime values, especially when the  
root bridge's helloTime is significantly less than other bridges in the tree. This  
issue has been resolved. Non-root bridges now adopt the root bridge's  
helloTime value propagated in BPDUs.  
PCR: 31135  
Module: IPV6  
Level: 3  
The ADD IPV6 HOST command accepted an invalid IPv6 address. This  
issue has been resolved.

SHOW IGMPSNOOPING ROUTERADDRESS  
Patch Release Note  
PCR: 31140  
Module: FIREWALL  
Level: 4  
The firewall sent an erroneous IPSPOOF attack message when processing  
large packets. This issue has been resolved.  
PCR: 31145  
Module: SWI  
Level: 3  
Level: 3  
Level: 3  
The port counters were not incremented:  
ifInDiscards  
ifinErrors  
ifOutDiscards  
ifOutErrors  
This issue has been resolved.  
PCR: 31146  
Module: SWI  
The following SNMP MIB objects could not be set:  
Dot1dStpPriority  
Dot1dStpBridgeMaxAge  
Dot1dStpBridgeHelloTime  
Dot1dStpBridgeForwardDelay  
This issue has been resolved.  
PCR: 31147 Module: DHCP  
DHCP was incorrectly using the directly connected network interface  
source IP address as the source IP address of packets it generates. This issue  
has been resolved. DHCP now uses the local IP address as the source  
address for the packets it generates when a local IP interface address is set.  
If a local IP interface address is not set, then it uses the IP address of the  
interface where packets are sent from as the source address.  
PCR: 31148  
Module: PIM, PIM6  
Level: 2  
When the device rebooted with PIM or PIM6 enabled, it sometimes did not  
send a Hello packet quickly enough. This issue has been resolved.  
PCR: 31152  
Module: DHCP  
Level: 2  
When a DHCP client was in the renewing state, and it sent a DHCP Request,  
the device did not add the ARP entry to the ARP table. Instead, the device  
generated an ARP Request in order to transmit the DHCP Ack. This caused  
a broadcast storm in the network when the client kept sending DHCP  
Requests. This issue occurred because the ciaddr field, not the giaddr field,  
was checked in the Request packet when the device determined whether to  
add the ARP entry. This issue has been resolved.  
PCR: 31153  
Module: IPG  
Level: 4  
In the output of the SHOW IP DNS CACHE command, “TTL” was  
displayed as seconds. This has been changed to minutes because the TTL is  
updated every minute.

PCR: 31154  
Module: STP  
Level: 4  
The current implementation of RSTP conforms to the IEEE standard  
802.1w-2001. However, several minor deviations from the standard are  
possible without having a functional impact on the behaviour of RSTP.  
These changes are useful for debugging RSTP, and tidy up aspects of RSTP  
that sometimes have no purpose. The following three variations have been  
implemented:  
The Learning and Forwarding flags are set in BPDUs to indicate the state  
of the Port State Transition state machine.  
The Agreement flag is set in BPDUs only when a Root Port is explicitly  
agreeing to a proposal from a designated port. Do not set the Agreement  
flag in BPDUs transmitted by Designated Ports.  
The Proposal flag is not set in a BPDU sent by a designated port once the  
port has reached the forwarding state.  
PCR: 31158  
Module: CORE  
Level: 3  
On AT-8800 series switches, when the fan status changed, the device did not  
send a SNMP trap and log. When the temperature was above the allowable  
threshold, the device sent the wrong SNMP trap. This issue has been  
resolved. Also, the temperature thresholds of the AT-8824 and AT-8848 have  
been set to different values of 62º C and 67º C respectively.  
PCR: 31159  
Module: FW, VLAN  
Level: 2  
Static ARP entries sometimes prevented the firewall from working  
correctly. This is because when an VLAN interface is added to the firewall,  
the CPU takes over the routing from the switch silicon in order to inspect  
the packet. Hence all the Layer 3 route entries must be deleted. However,  
static ARP Layer 3 entries were not being deleted from the silicon. This issue  
has been resolved. When interface is added to the firewall, all hardware  
layer 3 routing is now turned off to allow the firewall to inspect packets.  
PCR: 31161  
Module: LOG  
Level: 3  
If the number of messages to be stored in the TEMPORARY log output was  
changed with the SET LOG OUTPUT MESSAGE command, the SHOW  
LOG command output did not return any matching log messages. This  
issue has been resolved. Existing messages are now displayed.  
PCR: 31162  
Module: SWI  
Level: 2  
A STP topology change incorrectly deleted static ARP entries. This issue has  
been resolved.  
PCR: 31167  
Module: IPG  
Level: 2  
IP MVR member ports were not timing out. MVR member ports now  
timeout in the same way as IP IGMP ports. The timeout values are  
configured by IGMP. Also, IGMP interfaces were incorrectly being enabled  
and disabled by MVR. This issue has been resolved.  
PCR: 31170  
Module: SWI  
Level: 2  
After an AT-8800 series switch was powered down or rebooted, non-auto  
negotiating copper GBICs were not handled correctly. This issue has been  
resolved.

SHOW IGMPSNOOPING ROUTERADDRESS  
Patch Release Note  
PCR: 31171  
Module: PORTAUTH, USER,STP  
Level: 2  
This PCR enhances the robustness of the 802.1x port authentication  
protocol.  
PCR: 31174  
Module: IPG  
Level: 2  
If a device had IPSec and firewall enabled, it could not handle long ICMP  
packets even when enhanced fragment handling was enabled on the  
firewall. If a long packet is passed to the firewall for processing, the firewall  
chains the fragmented packets. The firewall can process chained packets,  
but IPSec could not process these packets, and dropped them. This was only  
an issue for packets between 1723 and 1799 bytes long. This issue has been  
resolved. The way IP processes fragmented packets has been changed so  
that IPsec no longer drops chained packets.  
PCR: 31179  
Module: SWI  
Level: 3  
Addresses learned with static port security were not added to the  
configuration when the CREATE CONFIG command was executed. This  
issue has been resolved.  
PCR: 31180  
Module: USER  
Level: 2  
The following commands did not require security officer privilege when the  
device was in security mode, but this privilege should have been required:  
ADD USER  
SET USER  
DELETE USER  
PURGE USER  
ENABLE USER  
DISABLE USER  
RESET USER  
This issue has been resolved. Security officer privilege is now required for  
these commands when security mode is enabled with the ENABLE  
SYSTEM SECURITY_MODE command.  
PCR: 31184  
Module: SW56  
Level: 2  
Some issues occurred on 48 port Rapier series switches when MAC  
addresses were learned and then relearned on a different port. These issues  
have been resolved.  
PCR: 31185  
Module: SWI  
Level: 2  
Tagged ports did not tag packets received from the bridge before  
transmitting them. This issue has been resolved.  
PCR: 31190  
Module: SWI, SW56  
Level: 2  
When static port security was enabled with the RELEARN parameter in the  
SET SWITCH PORT command, and a switch port was reset or unplugged,  
the MAC entries were removed (unlearned) from the forwarding database  
table. The MAC entries should only be removed when dynamic port  
security is in use. This issue has been resolved.

PCR: 31191  
Module: PORTAUTH, USER  
Level: 2  
A device in a supplicant role failed to authenticate if it used EAP-MD5  
encryption with Windows 2000 or 2003 Server as the RADIUS server. Also,  
a fatal error occurred if the device received EAPOL packets containing a  
very large value in the packet length field. These issues have been resolved.  
PCR: 31192  
Module: LOG  
Level: 3  
Syslog entries did not contain the date, time and unique identifier of the  
message source. This issue has been resolved. The CREATE LOG OUTPUT  
and SET LOG OUTPUT commands have been modified to control whether  
or not this information is included.  
The following parameter has been added to the CREATE LOG OUTPUT  
and SET LOG OUTPUT commands:  
[SYSLOGFORMAT=NORMAL|EXTENDED]  
If the SYSLOGFORMAT parameter is set to EXTENDED the date, time and  
unique identifier of message source are included in the syslog message. If  
the parameter is set to NORMAL, this information is not included in the  
syslog message. The default is NORMAL.  
PCR: 31193  
Module: IPG  
Level: 2  
When IP multicasting was not enabled, all IP multicast packets were passed  
to the CPU, causing overloading. This issue has been resolved. Now, if IP  
multicasting is not enabled, these packets are not sent to the CPU.  
PCR: 31194  
Module: BGP, IP  
Level: 3  
When executing the command:  
ADD IP ROUTEMAP ENTRY SET ASPATH  
followed by the command:  
ADD IP ROUTEMAP ENTRY COMMUNITY ADD=YES  
where the values for ROUTEMAP and ENTRY were the same in both  
commands, the second command failed and returned a “ROUTEMAP clause  
already exists” error message. This issue has been resolved.  
PCR: 31201  
Module: SW56, SWI  
Level: 2  
Fibre GBICs on Rapier and AT-8800 series switches sometimes did not  
establish a link when powered on for the first time. This issue has been  
resolved.  
PCR: 31205  
Module: VRRP  
Level: 3  
Two VRRP log messages were displayed when they should not have been.  
The log messages were:  
Vrrp 1: Vlan vlan2 10 Port Failed decrementing priority by 20  
Vrrp 1: Vlan vlan2 1 Port up incrementing priority by 2  
This issue has been resolved. These messages are now displayed at the  
correct time.

PCR: 03726  
Module: TTY, USER  
Level: 3  
The time recorded when a user logged in was overwritten when the same  
user logged in a second time while the original connection was still active.  
This meant the SHOW USER command displayed the same time for both
