The IPv6 routing table now recognises down routes. PCR: 02574 Module: DVMRP Network affecting: No Some change actions, and the resending of prune messages were not operating correctly. This issue has been resolved. PCR: 02587 Module: OSPF Network affecting: No When OSPF was enabled on startup, an OSPF interface would sometimes stay in the DOWN state. This issue has been resolved. Patch 86251-05 for Software Release 2.5.1 C613-10356-00 REV F Patch 86251-05 For Rapier Switches and AR800 Series Modular Switching Routers PCR: 03015 Module: SWI Network affecting: No When ports were added to a trunk group on a Rapier 16, the ports operated in the wrong duplex mode. This issue has been resolved. PCR: 03029 Module: SWI Network affecting: No Layer 3 filtering was not correctly modifying a packet's IPDSCP field. This issue has been resolved. PCR: 03031 Module: FIREWALL Network affecting: No The ADD FIREWALL POLICY RULE command included an erroneous check on port ranges for non-NAT rules. This check is now restricted to NAT rules. PCR: 03032 Module: SWI Network affecting: No If the ENABLE IP IGMP command was executed before the ENABLE SWITCH L3FILTER command, Layer 3 filtering did not discard packets destined for the CPU.

Availability Patches can be downloaded from the Software Updates area of the Allied Telesyn web site at A licence or password is not required to use a patch. Static IGMP This section describes an enhancement to the Internet Group Management Protocol (IGMP), which is supplied as a patch on Software Releases 2.5.1 for Rapier i Series switches. It is possible to have a network segment that either has no multicast group members, or has a host that is unable to report its group membership with IGMP. In such cases, no multicast traffic is sent to the network segment. This enhancement provides a mechanism for the user to pull down multicast traffic to the segment. Currently the switch forwards multicast data on a dynamic basis to hosts who have joined the multicast group. This enhancement allows the user to instruct the switch to forward multicast data over a specified interface and port, as shown in Figure 2 on page 25. This capability is essential for sending multicast traffic to hosts that cannot report their group membership with IGMP. It plays an important role in video over ADSL applications. Figure 2 on page 25 illustrates a switch forwarding the multicast stream to a set-top box after a user specifies that group 224.1.1.1 multicast data should be forwarded out of port 4 of VLAN1. Unlike conventional IGMP membership, this user-specified static membership never times out. The user will also be able to filter some IGMP debug messages by source IP address and group destination address. Patch 86251-05 fo...
