The levels are: Level 1 This issue will cause significant interruption to network services, and there is no work-around. Level 2 This issue will cause interruption to network service, however there is a work-around.
- Page 4 Features in 281-01 Software Maintenance Version 281-01 includes the resolved issues and enhancements in the following tables. In the tables, for each product series: ■ “Y” indicates that the resolution is available in Version 281-01 for that product series. ■ “-”...
- Page 5 Module Level CR00012933 Switch When STP is enabled on the switch but is disabled for a trunk (by using the command disable stp port), the trunk should pass traffic. Previously, some trunk members sometimes stayed in the “discarding” state instead. This issue has been resolved.
- Page 6 Level 2 Module Level Bridge The Bridge cannot be configured to bridge PPPoE packets from an Ethernet CR00009212 interface that has also been configured as a PPPoE interface. Previously, such a Bridge configuration would appear to succeed. However the Bridge would not bridge PPPoE packets and the router would restart when the command reset bridge was entered.
- Page 7 Module Level CR00011434 File The router or switch sometimes rebooted when copying a very large file (several Mbytes). This issue has been resolved by improving the copy process so that it uses fewer memory buffers. CR00011670 Switch On x900-48 Series switches, when the switch used a DSCP map to remark packets, it did not mark the packets correctly.
- Page 8 Module Level CR00012613 Firewall When the WAN load balancer was used with IP NAT (instead of firewall NAT), and an FTP session was established to a server on the public network, the router did not correctly establish a return session. This meant data was unable to flow correctly back from the server, and the router rebooted.
- Page 9 Module Level CR00012697 IPsec, ENCO Decrypting a large IPsec ESP packet sometimes caused the router or switch to reboot. This issue has been resolved. CR00012710 Core Soft errors can generate exceptions that would cause the router or switch to reboot. Soft errors are spontaneous changes in the information stored in a digital circuit, caused by physical effects.
- Page 10 Module Level CR00012846 ASYN, Log The following issues occurred with sending log messages to an asynchronous port: ■ The log messages output on an asynchronous port were corrupt. ■ When log messages were output to an asynchronous port, that port was (correctly) locked.
- Page 11 Module Level CR00012900 IPv6, Switch When an IPv6 accelerator card was installed, IPv6 multicast traffic was flooded to all ports in a downstream VLAN, whether or not they had joined the multicast group. This issue has been resolved. CR00012911 Switch, VLAN, Under very rare circumstances, memory corruption could occur when packets User were transmitted by the CPU out a switch port.
- Page 12 Module Level CR00013077 IPv6 When an IPv6 address was deleted on the router or switch, and that IPv6 address had previously been learnt by a remote IPv6 node, then the router or switch would reboot if it received an ICMPv6 Neighbour Solicitation message from the remote node.
- Page 13 Module Level CR00013529 PIMv6 When the router or switch used PIM for multicast routing, and an IPv6 multicast client joined a group, then left it, then attempted to rejoin it, sometimes the attempt to rejoin was not successful. This issue has been resolved. Level 3 Module Level...
- Page 14 Module Level CR00012468 OSPF An OSPF router or switch could show large numbers of entries in its retransmission lists to certain neighbours under certain conditions (for example, in a congested Frame Relay network). In some cases, the number of items in the list was larger than the number of LSAs in the database.
- Page 15 Module Level CR00012786 IP Gateway When a link that had RIP configured on it went down, so that the router or switch used an alternative route, output from the command show ip route sometimes displayed incorrect information when the link came back up. When the link first comes back up, the route's RIP metric is still 16, so the alternative route is still the “best”...
- Page 16 Module Level CR00013049 IPv6 The router or switch sometimes rebooted when it processed a large number of multicast routes that were created as the result of receiving a large amount of data from more than 500 multicast groups. This issue has been resolved. CR00013085 OSPF A user can configure a range on an OSPF ABR, so that the ABR aggregates the...
- Page 17 Module Level CR00013243 Core The system LED did not indicate when an internal power supply fault occurred. This issue has been resolved. The system LED now flashes 3 times to indicate a fault. Also, output of the show system command now reports voltages more accurately.
- Page 18 Level 4 Module Level When the web-based GUI is used to add or remove ports from a port-based CR00010159 VLAN association on an AT-9812T switch, the icons representing alternate ports faced opposite directions. This issue has been resolved. The port icons now all have the same orientation. IPsec In output of the commands show ipsec policy and show ipsec policy CR00011311...
- Page 19 Module Level CR00012270 Remote Telnet The “?” help description for the enable command stated that the parameter rtelnet would “Disable the use of remote telnet to control an asyn port”. This issue has been resolved. The query now states that the command enable rtelnet enables remote telnet.
- Page 20 Module Level CR00012916 L2TP When the router or switch was configured as an LNS and received an incoming L2TP call that was associated with a disabled PPP interface, it produced an incorrect log message. This issue has been resolved. CR00012946 When a user entered the command show log receive=ipadd, information about all IP addresses was displayed unless the user also entered the mask parameter.
- Page 21 Enhancements Module Level Bridge By default, when the router receives a tagged packet on an Eth or VLAN interface CR00012620 and bridges it, the bridge strips out the packet’s VLAN tag. This enhancement enables you to set the bridge to instead retain the tag, by using off, no or false in the new command: set bridge stripvlantag={on|off|yes|no|true|false} The default is on.
- Page 22 Module Level CR00012850 File Previously, a user could delete the preferred software release and the current boot configuration file (by using the command delete file), without first setting CR00013109 a new preferred release or boot configuration file. Therefore, it was possible to accidentally delete these files, which caused network disruptions if the router or switch restarted.
