Patch 89262-08 For AT-8900 Series Switches PCR: 40596 3 Module: SWMX Level: 2 When STP is enabled, when frames with a multicast destination MAC address were sent, a loop was observed within the network. This issue has been resolved. PCR: 40601 Module: SWMX Level: 2 In network configurations with multiple paths to neighbours on an interface, if the interface changed state from up to down, then up again, the interface route may have been erroneously deleted by a route update.
Patch Release Note PCR: 40618 Module: SWI Level: 3 Fixing speed on a fibre SPF to 1000mfull in a configuration script showed up incorrectly as 10mfull actual speed after reboot. This issue has been resolved. Level 4 No issues. Enhancements No issues. Features in 89262-07 Patch file details are listed in Table 1. Table 2: Patch file details for Patch 89262-07.

Patch 89262-08 For AT-8900 Series Switches 5 4) Not all routes were removed from the BGP route table when a peer was disabled. These issues have all been resolved. PCR: 40419 Module: OSPF, IPG Level: 2 If OSPF was configured using the command set ospf dyninterface=stub, to advertise dynamic interfaces such as PPPoE interfaces as stub links, the links were not being advertised as expected. This issue has been resolved.
Patch Release Note PCR: 40473 Module: IPG Level: 2 When IP filters are configured on IP interfaces of the switch, all IP routing must occur in software. To achieve this, the IP forwarding table in the ASIC must be emptied. There was an issue whereby Interim IP route entries (IP routes for which there is not yet an ARP entry for the nexthop address) were not removed from the hardware IP forwarding table when an IP filter was added to an IP interface. This issue has been resolved.
Patch 89262-08 For AT-8900 Series Switches PCR: 40510 7 Module: VRRP Level: 2 A configuration generated with the create config or show config dynamic commands could under some circumstances, include a disable vrrp = command even if VRRP was enabled. This issue has been resolved. PCR: 40516 Module: DHCP Level: 2 While initialising a range, the switch acting as a DHCP server may release a dynamic entry incorrectly. This issue has been resolved.
Patch Release Note PCR: 40540 Module: SWI Level: 2 Problems could occur if hardware filters or QOS policies were created using a classifier matching on: a Layer 2 attribute other than MAC Destination (e.g. MACSA or VLAN ID), and one or more other parameters that match on IPv4 frames (e.g. IP address, UDP/TCP parameters), and another classifier matching on Layer 2 attributes only.
Patch 89262-08 For AT-8900 Series Switches PCR: 40562 9 Module: SWNP Level: 2 If the command enable switch accelerator function=icmpredirect had been executed, there was no resulting entry in a script subsequently created by the create config or show config dynamic commands. This issue has been resolved. PCR: 40565 Module: SWMX Level: 2 If two protocol VLAN association rules were added to two different VLANs, the second protocol association rule would not work. This issue has been resolved.
Patch Release Note PCR: 40498 Module: OSPF Level: 3 When a virtual link end point is no longer reachable, the virtual interface is not brought down, and the virtual neighbour is not removed. This issue has been resolved. PCR: 40515 Module: QoS Level: 3 Setting switch enhanced mode to “none” in order to disable QoS counters did not disable the QoS counters properly. A debug error message was shown when attempting to view the traffic class counters.

Patch Release Note transmitted while the IPsec SA renegotiation took place. This issue has been resolved. PCR: 40340 Module: IPG Level: 3 The IP Options fields were being processed multiple times if a Firewall or NAT were enabled. This resulted in two Timestamps or Record_Route fields being added at each hop, instead of one. This issue has been resolved. PCR: 40350 Module: OSPF Level: 2 All OSPF packets sent had an IP Precedence of 0 rather than 110. This issue has been resolved.
Patch 89262-08 For AT-8900 Series Switches PCR: 40411 13 Module: IP6 Level: 2 In certain cases where static routes in a multi-path environment were used and routes were changed on the switch, the IPv6 flow table of the switch wasn't refreshed correctly, i.e. an entry in the flow table had no outgoing interface and ND entry. This issue has been resolved. PCR: 40413 Module: QOS Level: 3 The command reset qos accel was generating an unexpected error message. This issue has been resolved.
Patch Release Note PCR: 40431 Module: SWMX Level: 2 When the IPV6 accelerator card was present but disabled, the switch was not transmitting CPU-initiated packets after receiving non-reserved multicast packets. This issue has been resolved. PCR: 40433 Module: VLAN Level: 2 When the nested VLAN feature was disabled using the disable feature command, the switch did not remove, from software and hardware, all of the nested VLAN’s associated ports, protocols and subnets as well as the nested vlans.
Patch 89262-08 For AT-8900 Series Switches PCR: 40463 15 Module: IPG Level: 2 Under the IPv6 multipath environment, e.g. when both a static route and a RIPng route were available, if the static route was disconnected, the switch used the CPU to transmit outgoing packets on the RIPng Route, i.e using software routing. This issue has been resolved. PCR: 40509 Module: SWMX Level: 3 NetBios responses to NetBeui packets were not being classified by a protocol based VLAN.

Patch 89262-08 For AT-8900 Series Switches PCR: 40365 17 Module: EZDRV, IPv6, SWNP Level: 2 When a large number of IPv6 interfaces were configured: • a boot script could take several minutes to process • processing multicast updates could take several minutes • high packet loss sometimes occurred when updating hardware for a change in IPv6 multicast membership These issues have been resolved.
Patch Release Note PCR: 40382 Module: SWMX Level: 3 The IPv6 Accelerator Card port (port 53) can only be associated with a QOS policy containing classifiers that specify ethii-tagged as the Ethernet encapsulation and IPv6 as the protocol: create classifier=rule-id ethformat=ethii-tagged protocol=ipv6 [other-parameters...] The add qos port command now checks that all classifiers associated with the QoS policy being assigned to the port specify ethformat=ethii-tagged and protocol=ipv6.
Patch 89262-08 For AT-8900 Series Switches PCR: 40249 19 Module: SWI, SWMX Fibre SFPs can now be set to a fixed speed. Copper SFPs still can not have their speed parameters modified. PCR: 40270 Module: PIM6 The maximum number of PIM6 interfaces has been increased from 255 to 2000. The number of MLD interfaces has also been increased to 2000 to match the maximum number of PIM interfaces.
Patch Release Note PCR: 40318 Module: IPV6 Level: 2 The next hop of an IPv6 RIPng Response message was not assigned with a link local address when an invalid next hop was specified in the prefix field of the route table entry. This issue has been resolved. PCR: 40322 Module: TM Level: 3 An error message was not returned if an unavailable interface was specified for the enable test interface command. This issue has been resolved.

Patch 89262-08 For AT-8900 Series Switches show ip igmp 23 IGMP Snooping All-Group Entry Because IGMP is an IP-based protocol, multicast group membership for VLAN aware devices is on a per-VLAN basis. If at least one port in the VLAN is a member of a multicast group, multicast packets will be flooded onto all ports in the VLAN by default. IGMP snooping enables the switch to forward multicast traffic intelligently on the switch.
enable ip igmp allgroup Patch Release Note Figure 1: Example output from the show ip igmp command. IGMP Protocol -------------------------------------------------------------------------------Status ........................... Enabled Default Query Interval ........... 125 secs Default Timeout Interval ......... 270 secs Disabled All-groups ports ........ 1,5,7 Interface Name .......... vlan2 (DR) IGMP Proxy ..............

Patch 89262-08 For AT-8900 Series Switches disable ip igmp allgroup 25 The ALLGROUP parameter specifies the list of ports able to behave as allgroup entry ports. If ALL is specified, all ports are able to behave as all-group entry ports. The default is ALL.
add igmpsnooping routeraddress ■ RIP2 routers, 224.0.0.9 ■ All PIM routers, 224.0.0.13 ■ All CBT routers, 224.0.0.15 Patch Release Note If IP is specified, addresses treated as router multicast addresses are specified by the user using the ADD IGMPSNOOPING ROUTERADDRESS and the DELETE IGMPSNOOPING ROUTERADDRESS commands. When in this mode, the switch retains previous addresses that have already been specified.
Patch 89262-08 For AT-8900 Series Switches delete igmpsnooping routeraddress 27 set igmpsnooping routermode Syntax Description SET IGMPSNOOPING ROUTERMODE= {ALL|DEFAULT|IP|MULTICASTROUTER|NONE} 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.
show igmpsnooping routeraddress Patch Release Note show igmpsnooping routeraddress Syntax Description SHOW IGMPSNOOPING ROUTERADDRESS This command displays information about the list of configured IP multicast router addresses currently configured on the switch (Figure 2 on page 28).

Patch 89262-08 For AT-8900 Series Switches show igmpsnooping routeraddress 29 Importing BGP routes into OSPF Introduction With this enhancement you can import routes from BGP into OSPF. OSPF will then redistribute these routes. This enhancement adds three parameters to the set ospf command, and modifies the output of the show ospf command. The new parameters are bgpimport, bgpfilter and bgplimit.
set ospf Patch Release Note Configuration example This example supposes that you want to import the route 192.168.72.0 into the OSPF routing domain, but no other routes. This route is received on the gateway router as a BGP route. The following steps show the sequence of commands to use in this scenario. 1. Set up the IP filter: add ip filter=300 source=192.168.72.0 smask=255.255.255.255 action=include 2. Set up OSPF BGP import parameters: set ospf bgpimport=on bgpfilter=300 bgplimit=1 3.
Patch 89262-08 For AT-8900 Series Switches show ospf 31 Parameter Option/Range Description BGPLimit 1...300 The maximum number of BGP routes that can be imported into OSPF at a time. Once this limit is reached, importing stops until existing routes are removed. The default is 300. *Caps denote command shortcuts show ospf Syntax Description SHow OSPF This command displays information about the general configuration of OSPF routing (Figure 3 on page 31, Table 11 on page 31).
add ip filter Patch Release Note add ip filter Syntax Description ADD IP FILter=filter-number {ACTion=INCLude|EXCLude} SOurce=ipadd [SMask=ipadd] [ENTry=entry-number] [otherparameters] This command adds a pattern to a routing filter. For details about the command parameters, see Table 12 on page 32. Table 12: Parameters for the BGP route import feature in the add ip filter command.
