  • Page 5 Enhancements Module Level CR00012881 IP Gateway The IP implementation has been enhanced to accept IP interfaces with a /31 netmask. This results in a slightly non-standard subnet that has no network address or broadcast address. This has become a popular extension to IP, because it reduces wastage of IP addresses on point-to-point links.

  • Page 7 Module Level CR00011994 IPsec When both Software QoS and IPSec were configured on the router or switch, it sometimes rebooted. This happened if the IPSec SA bundle was suddenly deleted while packets were still queued in Software QoS. For example, this issue was more likely to occur if the expirykbytes parameter of the create ipsec bundlespecification command was configured, and the hard expiry kilobyte limit for an IPSec SA bundle was reached quickly.
  • Page 8 Module Level CR00013413 IP Gateway, If the router or switch was configured with a local interface IP address and the Load Balancer interface to which this address belonged did not have a logical interface with index 0, a number of connectivity issues from this router or switch occurred, in which the router or switch was not able to communicate with UDP, TCP or PING.
  • Page 9 Level 2 Module Level CR00009079 When MLD snooping creates an All Router group, it also (correctly) adds router Snooping, ports to other groups. However, when MLD Snooping detected that there were IPv6, Switch no more router ports in the network, it deleted the All Router group but did not delete the router ports from the other groups.
  • Page 10 Module Level CR00010177 Firewall When a session had been initiated from the LAN side of the firewall and the SIP ALG received a re-invite packet for that session from the WAN side, the SIP ALG did not replace the Call ID string in the re-invite packet. This issue has been resolved.
  • Page 11 Module Level CR00011490 MLD, The following issues occurred: MLD Snooping ■ an MLDv2 Report message parsing issue meant that sometimes the router or switch recognised only the first multicast group address in the message. ■ if the robustness, qinterval or qrinterval were changed, groups’ initial timeout period was sometimes set to 260 instead of being calculated by using the following formula from RFC 3810: robustness * qinterval + qrinterval...
  • Page 12 Module Level CR00011907 IP Gateway Previously, if the IP Helper attempted to redirect packets to an address that matched the network broadcast address of the egress interface, the packets were only forwarded if directedbroadcast=yes for the egress interface. By default, directedbroadcast=no, so such packets were dropped.
  • Page 13 Module Level CR00012624 VRRP, Under certain network conditions in which VRRP entities become temporarily IP Gateway unsynchronised, the router or switch could receive a gratuitous ARP from a self- elected VRRP master when the router or switch was still the master. This caused the existing master to create an ARP entry that incorrectly redirected packets towards the other VRRP entity even after the other entity had become a slave again.
  • Page 14 Module Level CR00012743 IP Gateway When a device that is connected to a router or switch interface leaves a multicast group, the router or switch (correctly) responds by sending out a Query message over that interface. In the default configuration, it also sends a second Query message one second later, for redundancy.
  • Page 15 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 16 Module Level CR00012952 Bridge If a tagged packet was bridged out of a VLAN interface, the interface always added a VLAN tag into the packet, even though the packet was already tagged. This issue has been resolved. The maximum allowed value of the vpi parameter in the commands add and set CR00012991 atm channel has been increased from 8 to 15.
  • Page 17 Module Level CR00013083 TACACS+, User After a very large number of successful logins via TACACS+ authentication, the router or switch would reboot. This issue has been resolved. IPv6 When the router or switch learned a better IPv6 route to exactly the same CR00013096 destination as an existing route, the router or switch did not always change CR00013718...
  • Page 18 Module Level CR00013437 If a PRI or BRI interface had severe transmission difficulties due to a faulty communications link, it could cause the router or switch to reboot. This issue has been resolved. A faulty PRI or BRI communications link can no longer take the whole router or switch down.
  • Page 19 Level 3 Module Level CR00008192 Switch The following issues occurred with the counters that are displayed by the show interface=port-number counter command: ■ If a switch port received a broadcast or multicast packet with an error (such as a bad CRC error), the ifInUcastPkts counter—the number of unicast packets received—...

  • Page 22 Module Level CR00012895 IP Gateway Previously, the router accepted ARP entries with multicast IP and MAC addresses when the MAC disparity feature was disabled. The MAC disparity feature is disabled by default. The issue has been resolved. The router now discards such ARP entries unless the MAC disparity feature has been enabled by using the command enable ip macdisparity.
  • Page 23 Module Level CR00013421 When a user created a BGP module trigger for the peerstate event, the router or switch did not allow specification of the script or state parameters. This issue has been resolved. All such generic parameters are now available with module-specific triggers.
  • Page 24 Level 4 Module Level CR00001359 Eth, Bridge, For all Ethernet-like interfaces, the router or switch now uses an ifType value of Switch, LLDP, ethernetCsmacd, instead of the deprecated value of iso88023Csmacd. IP Gateway Core If the router had a temperature lower than zero, it displayed the temperature as CR00009443 a positive number in, for example, the command show system.
  • Page 25 Module Level CR00011311 IPsec In output of the commands show ipsec policy and show ipsec policy sabundle, the value for the number of bytes currently used by each SA bundle was sometimes truncated. This issue has been resolved, and both commands now display the correct number.
  • Page 26 Module Level CR00012774 IP Gateway, In an unusual network configuration where the IP subnet on one interface was a subset of that on another interface, it was possible for the results of a trace route to show erroneous information. This issue has been resolved. A search for an interface using an address within the interface's subnet now finds the most specific match for the address.
  • Page 27 Enhancements Module Level CR00011490 MLD, Several enhancements have been made to MLD and MLD Snooping, in accordance with RFC 3810, Multicast Listener Discovery Version 2 (MLDv2) for IPv6. For details, see Snooping on page This CR also fixed some issues in MLD and MLD Snooping; see on page CR00012015 BGP backoff has been enhanced in the following ways:...
  • Page 28 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 CR00013683 switch restarted.

  • Page 31 Level 2 Module Level CR00000529 IPv6, When a better route for multicast traffic became available, PIM for IPv6 did not recalculate the route and switch the traffic to use it. PIM6 This issue has been resolved. CR00006475 IP Gateway, When PIM-DM or PIM-SM was forwarding traffic through the CPU at high data rates and an SG entry was deleted, it was possible for the router or switch to reboot.
  • Page 32 Module Level CR00008699 Switch Previously, when 300 MAC address filters were added to a port and the port was reset, the CPU became 100% utilised. This issue has been resolved. CR00008992 IPv6 The router or switch sometimes unexpectedly stopped forwarding IPv6 multicast traffic if the multicast’s upstream path changed.
  • Page 33 Module Level CR00010886 IPv6, When a user enabled a Dial-on-Demand PPP interface, sometimes the router or switch did not apply the associated IP route change. This meant that routes via IP Gateway, the Dial-on-Demand PPP interface were not available for use. When this occurred, routed traffic failed to activate the associated Dial-on-Demand PPP interface.
  • Page 34 Module Level CR00011349 At low baud rates, a synchronous connection was unable to reach 100% utilisation of the available bandwidth. The queueing mechanism has been improved to allow 100% link utilisation. Flag sharing between back-to-back HDLC frames is now supported for synchronous connections. CR00011396 PIM on IPv6 When a user specified a static RP candidate and saved the configuration with the...
  • Page 35 Module Level CR00011665 When using an unstructured TDM group over an E1 mode PRI interface, occasionally a high level of errors was experienced. This may have caused the link to be unstable, or may have resulted in reduced data throughput. This issue has been resolved.
  • Page 36 Module Level CR00011855 TCP, TCP sessions would sometimes “hang” in the Close Wait state. This behaviour occurred when a UPnP notification session was closed by the control point UPnP (usually Windows XP, SP2), via a “200 OK” message that contained a “Connection: close”...
  • Page 37 Module Level CR00012013 VLAN When MLD snooping was enabled and the switch received IPv6 multicast packets (such as MLD Query, Report or Done messages; IPv6 NS packets; and IPv6 RA packets) on a non-master port of a trunk group, it incorrectly forwarded them out the master port.
  • Page 38 Module Level CR00012140 If the link between two PIM Sparse Mode neighbours was removed, sometimes one of the neighbours rebooted. This issue has been resolved. CR00012167 Switch When MAC address entries time out in the switch’s ARP table, the switch re-ARPs for the entry’s MAC address and adds the entries back if it gets a reply.
  • Page 39 Module Level CR00012304 TPAD TPAD previously had issues when the LRC (Longitudinal Redundancy Check) at the end of a transaction was 0x00 and the transaction was via the TCP port. The transaction would stall in the box and eventually time out the X.25 call. This issue has been resolved.
  • Page 40 Module Level CR00012482 Core, Utility, A few commands on the switch are local commands—they relate only to the Stacking switch on which the user types them, and not to any other switch in the stack. The edit command is one such command. Previously, local commands were directed across the stack, which meant they could be sent to other stack members.
  • Page 41 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 42 Level 3 Module Level CR00006900 BGP, If the metric on a blackhole route was changed using the command set ip route and this caused another route, which was being suppressed by the blackhole IP Gateway route, to become preferred, that route could sometimes fail to be imported into BGP.
  • Page 43 Module Level CR00010508 When the router or switch received a BGP update message and created new prefix entries for the routes in the update, it reversed the order of the AS segments. This issue has been resolved. CR00010952 IPv6 If either of the following were configured for MLD: ■...
  • Page 44 Module Level CR00011510 IPsec The maximum SPI value has been increased in the commands: create ipsec saspecification=spec-id inspi=spi set ipsec saspecification=spec-id inspi=spi outspi=spi The spi is now an integer in the range 256 to 4294967295. CR00011659 TTY, VRRP When VRRP debug was enabled from a telnet session, the debugging did not stop when the telnet session closed.
  • Page 45 Module Level CR00011888 Switch When a trunk group on a 48-port switch spanned multiple switch instances, the switch sometimes did not transmit traffic. The ports in each instance are: Models Rapier 48i, AT-8748XL, AT-8648T /2SP AT-8848 This issue has been resolved. CR00011931 VLAN After users added multiple ports to one private VLAN as tagged ports, those ports...
  • Page 46 Module Level CR00012036 Firewall Previously, the command set firewall policy=policy-name othertimeout=minutes did not change the timeout period for firewall GRE sessions. This issue has been resolved. Note that when a firewall session establishes, its timeout is initially set to 5 minutes. Once the session processes two or more packets, its timeout changes to the value specified by this command.
  • Page 47 Module Level CR00012283 Switch Previously, it was not possible to create two protocol-based VLANs on the same ports if they had the same protocol but a different Ethernet encapsulation. This issue has been resolved, so you can now create such VLANs. CR00012305 When a user entered a maxbandwidth for QoS, the switch sometimes displayed a message that said the bandwidth units were “kbytes”...
  • Page 48 Module Level CR00012329 Asyn When the router sent a continuous stream of data over a permanent assignment, and the ASYN port at the receiving end of the tunnel was significantly slower than the ASYN port at the sending end, the sending router eventually rebooted. This was because the router had to queue packets and eventually ran out of memory.
  • Page 49 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 50 Level 4 Module Level CR00003286 Core, ISDN Previously, the log message generated when an ISDN call came up sometimes reported the channel as “channel unknown” when the channel was encoded as a channel map instead of a channel number. The type of encoding depends on the local ISDN provider, so this issue only occurred in some parts of the world.
  • Page 51 Enhancements Module Level CR00007105 MSTP Two new commands have been added to simplify MSTP management: enable mstp port={port-list|all} disable mstp port={port-list|all} These commands enable or disable MSTP on the specified ports for the CIST and all currently-configured MSTIs, in a single step. Previously, this operation required two commands.
  • Page 52 Module Level CR00011204 IP Gateway This Software Version allows you to add ARP entries with multicast MAC addresses and allows the router or switch to accept packets with conflicting IP and MAC addresses. It introduces the enable ip macdisparity and disable ip macdisparity commands to support this.
  • Page 53 Module Level CR00012620 Bridging By default, when the router receives a tagged packet on an Eth or VLAN interface 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 55 Module Level CR00008742 Switch Previously, if a switch port’s learn limit was changed to a number that was less than the currently-learned number of MAC addresses, you were unable to delete the learned MAC addresses. The switch also did not lock the port. This issue has been resolved.
  • Page 56 Module Level CR00010539 Sometimes the forwarding of packets occurred unnecessarily slowly. This happened if the forwarding interface was associated with an IP filter with a variable field pattern, such as TCP session or ICMP code and type. For switches, note that this issue occurred when the switch was routing IP packets in software, and had no effect on the hardware forwarding of packets.
  • Page 57 Module Level CR00010896 Switch AT-40/SC, AT-40/MT and AT-41/MT uplink modules would stay link down when they were set to a fixed speed. This issue has been resolved. CR00010996 Port When port authentication was using a RADIUS server, it sometimes stopped Authentication working after several hours.
  • Page 58 Module Level CR00011213 PIM 6 Previously, the switch treated a valid bootstrap message as a bad message if it received the message on two or more interfaces, and when PIM6 operated in a looped or network topology that had multiple unicast routes to the same destination(s), it sometimes selected a sub-optimal route for RPF interface selection for RP and BSR elections.
  • Page 59 Module Level CR00011324 A reboot could occur when the SSLv2 client received a hello message that had an incorrect challenge length. This issue has been resolved, so that the SSL server’s resistance to denial of service attacks has been improved. CR00011328 When the switch was using PIM to route multicast traffic, it sometimes rebooted if the command show switch table=nh was entered.
  • Page 60 Module Level CR00011585 OSPF Adding the same OSPF stub or host twice caused OSPF to suspend its operation, causing neighbour relationships to eventually fail. This issue has been resolved. CR00011611 IP Multicast The router or switch did not forward multicast traffic addressed to 239.255.255.250, even when the router or switch was not involved with UPnP service discovery.
  • Page 61 Level 3 Module Level CR00006439 When a user logged onto the router or switch through the GUI, the router or switch’s log recorded several HTTP 404 (Not Found) errors. This was because the browser expected to see some images that the GUI resource file did not contain. This issue has been resolved.
  • Page 62 Module Level CR00011664 PERM The IAC (interpret as control) characters (0xFF) are escaped when sent across the permanent assignment connection. If TCP could not send the entire buffer, the two IAC characters were previously split up, which resulted in extra IAC characters in the receive buffers.

  • Page 67: Adding Static Arp Entries

    Adding Static ARP Entries with Multicast MAC Addresses (CR00011204) This Software Version allows you to add ARP entries with multicast MAC addresses and allows the router or switch to accept packets with conflicting IP and MAC addresses. It introduces the enable ip macdisparity and disable ip macdisparity commands to support this. Adding Static ARP Entries Valid ARP entries are normally restricted to unicast IP with unicast MAC addresses.
  • Page 68 Adding Static ARP Entries with Multicast MAC Addresses (CR00011204) To see whether macdisparity is enabled or disabled, use the command: show ip For an example of how to use ARP entries with multicast MAC addresses, see Guideline to Windows 2003 Network Load Balancing Clustering with Allied Telesyn Switches.
  • Page 69 Securing a Single VLAN through Switch Filters (CR00011271) On AT-8824, Rapier 24i, AT-8724XL and AT-8624 switches, this enhancement enables you to use switch filters to secure only the current VLAN, instead of securing all VLANs on the switch. To turn on this feature, a new command disables “vlansecure” for filters (see this enhancement (the default situation) a switch filter only allows a host to access the network through a particular port on the switch.
  • Page 70 Configuring vlansecure To turn off the default behaviour, so that the filter prevents access to only the current VLAN when you move the host, use the new command: disable switch filter vlansecure To return to the standard filter behaviour, use the new command: enable switch filter vlansecure To display which mode the filtering behaviour is in, use the existing command: show switch filter...
  • Page 71 Making Asynchronous Ports Respond More Quickly (CR00011565) When an asynchronous port is in ten mode, it bundles together the characters that it receives within a certain time period, instead of passing them one at a time to a higher protocol layer for processing. The time period over which characters are bundled is set by the ten timer. Bundling reduces the load on the CPU by spreading the character processing overhead across several characters.

  • Page 76 Permanent Assignments (CR00011355) Permanent assignments provide a method for creating permanent links between terminal ports on routers. Any two terminal ports on a single router or on routers that can communicate with each other via TCP/IP can be set up to have a permanent assignment between them. Asynchronous traffic coming into each port is sent via TCP to other port and then sent out that port.
