  • Page 2 Features in 86241-06 Patch 86241-06 includes all issues resolved and enhancements released in previous patches for Software Release 2.4.1, and the following enhancements: PCR: 02429 When more than two firewall policies were configured, an unexpected switch restart sometimes occurred. This issue has been resolved.
  • Page 3 Patch 86241-06 For Rapier Switches PCR: 03056 During an SSH session between the switch and the Secure CRT client, the client did not receive a reply to its MAX-packet-size CMSG. The switch does not support this message, but will now send a negative response to satisfy the secure CRT client’s requirements.
  • Page 4 PCR: 03100 DHCP was assigning incorrect IP addresses to clients when they moved from a relayed to a non-relayed range. Gateway checks have been added to remove this issue. PCR: 03101 Deriving the originating VLAN from incoming packets could, in some circumstances, cause a software restart.
  • Page 5 Patch 86241-06 For Rapier Switches PCR: 03123 After sending a DHCP NAK in response to a client’s DHCP REQUEST with a bad lease time, the switch would fail to age out its corresponding DHCP OFFER entry. This issue has been resolved.
  • Page 6 Features in 86241-05 Patch file details are listed in Table 2: Table 2: Patch file details for Patch 86241-05. Base Software Release File Patch Release Date Compressed Patch File Name Compressed Patch File Size Patch 86241-05 includes all issues resolved and enhancements released in previous patches for Software Release 2.4.1, and the following enhancements: PCR: 02315 Support has been added for SNMPv2c.
  • Page 7 Patch 86241-06 For Rapier Switches PCR: 03002 Debugging commands are now available for the RADIUS and TACACS control protocols. Raw packets, decoded packets, and errors can now be displayed. Access control packet debugging allows the contents of the packets to be viewed.
  • Page 8 PCR: 02340 PIM was disabled permanently if the RESET IP command, or the DISABLE IP command followed by the ENABLE IP commands were executed. PIM is now automatically restarted if these commands are used. PCR: 02356 Previously the SET FIREWALL POLICY RULE command permitted the use of the GBLIP and GBLPORT parameters in ways that were not permitted by the ADD FIREWALL POLICY RULE command.
  • Page 9 Patch 86241-06 For Rapier Switches PCR: 02519 The DELETE IPV6 6T04 command sometimes caused an error. This issue has been resolved. PCR: 02521 The DECREMENT parameter of the ADD IPV6 INTERFACE command was not recognised in the command line. This issue has been resolved.
  • Page 10 PPP interface speed. This issue has been resolved so that the LNS side of the PPP interface shows the correct speed. PCR: 02538 The source mask is now always 0xffffffff in the DVMRP forwarding table. The temporary route in the DVMRP route table was not displaying correctly.
  • Page 11 Patch 86241-06 For Rapier Switches PCR: 02574 Some change actions, and the resending of prune messages were not operating correctly. This issue has been resolved. PCR: 02579 The ADD FIREWALL POLICY and SET FIREWALL POLICY commands did not generate a valid port list when the optional PORT parameter was set to ALL.
  • Page 12 PCR: 02469 After an ASYN port test, the port is now reset to its pre-test state if the test was started by a user connected to the same ASYN port. PCR: 02477 The following issues have been resolved: • • •...
  • Page 13 Patch 86241-06 For Rapier Switches PCR: 02502 If multiple IPv6 interfaces shared the same link-local address, pings to the link-local address sometimes failed. This issue has been resolved. PCR: 02509 The source net mask has been removed from DVMRP prune, graft and graft-ack messages.
  • Page 14 PCR: 02263 The virtual MAC address was used as the source MAC for all packets forwarded on an interface associated with a Virtual Router (VR). This was confusing when multiple VRs were defined over the same interface because only one virtual MAC address was ever used. The other virtual MAC addresses (for the other VR's) were only used if the source IP address matched the VR’s IP address.
  • Page 15 Patch 86241-06 For Rapier Switches PCR: 02292 IPSec no longer logs packets that match an ACTION=ALLOW policy. The overhead of this logging was affecting non-IPSec traffic. PCR: 02294 The LOCALRSAKEY parameter in the CREATE ISAKMP POLICY and SET ISAKMP POLICY commands was not accepting the value zero. This issue has been resolved.
  • Page 16 PCR: 02313 The SHOW IPV6 INTERFACE command now shows the address lifetime aging status that is determined by the DECREMENT parameter in the ADD IPV6 INTERFACE command. The default valid and preferred address lifetimes have been changed to 30 days and 7 days respectively. PCR: 02320 The interface address preferred lifetime was not operating correctly.
  • Page 17 Patch 86241-06 For Rapier Switches PCR: 02335 The SHOW CLASSIFIER command was not displaying Layer 3 information if the classifier had been created with the parameters ETHFORMAT=SNAP and PROTOCOL={IP|0000000800}. This issue has been resolved. PCR: 02343 When acting as a PPPoE Access Concentrator (AC), if a PPPoE client sent discovery packets without the "host-unique"...
  • Page 18 PCR: 02359 When an IP Multihomed interface was used as an OSPF interface, neighbour relationships were only established if the IP interface for OSPF was added first in the configuration. Now, OSPF establishes neighbour relationships regardless of the IP Multihomed interface configuration order. PCR: 02363 The FLASH compaction process is now transparent to the file edition process.
  • Page 19 Patch 86241-06 For Rapier Switches PCR: 02398 The following issues have been resolved: • • • RIPv6 now sets the metric of routes for interfaces that are DOWN to 16, and immediately sends responses when the link status of VLAN interfaces changes.
  • Page 20 PCR: 02412 An ISDN call was activated by IPv6 Router Advertisements over IPv6 tunnel interfaces. This issue has been resolved. PCR: 02415 Packets with a RIP source address and next hop address that are not on the same subnet as the interface will now be processed. If the received next hop is not on the same subnet, it is treated as 0.0.0.0.

  • Page 22 but is now checked by ICMP handlers for attacks and eligibility. If the ICMP traffic matches a NAT rule, NAT will occur on inbound and outbound traffic. HTTP 1.0 requests sometimes caused the firewall HTTP proxy to close prematurely. Cached TCP sessions were sometimes not hit correctly. These issues have been resolved.
  • Page 23 Patch 86241-06 For Rapier Switches into 8 blocks of 85 bits with 84 bits available for payload, and one bit for framing overhead. The frame structure is shown in Figure 1 on page 23. Figure 1: DS3 Framing Structure. The switch with the DS3 interface is called the near end. The entity the switch connects to is called the far end.
  • Page 24 The three C-bits in M-subframe 4 are designated as FEBE bits. The FEBE bits are returned to the far end to indicate the occurrence of a framing error or CP- bit parity error. If none occur, the FEBE bits are set to all ones. One or all of the FEBE bits are set to zero if a CP-bit parity error or an error in the F or M bits is found.
  • Page 25 Patch 86241-06 For Rapier Switches Diagnostic loopback is shown in Figure 3 on page 25. In this loopback mode the transmit signal is connected straight to the receive signal. Figure 3: Diagnostic Loopback. In C-bit parity mode it is also possible for the switch to request a loopback at the far end.
  • Page 26 Patch Release Note maintenance link allows a number of identification messages to be inserted in to the path overhead of the DS3 signal. These messages are in the form of text characters and allow the users at either end of the DS3 path to ensure that the correct DS3 signal has reached their equipment.
  • Page 27 Patch 86241-06 For Rapier Switches The PARAM24 parameter specifies the 24-hour counter threshold for all performance monitoring parameters (PES, PSES, SEF, UAS, LES, CES, CSES) between 1 and 65535 seconds inclusive. If a trigger has been created, it will assert if the 24-hour count exceeds the value specified in PARAM24. The default is 65535 seconds.

  • Page 29 Patch 86241-06 For Rapier Switches Dynamic Port Security Dynamic Port Security allows for dynamic MAC address learning on a switch port. If a MAC address is unused for a period of time, it will be aged from the database of currently accepted MAC addresses. This allows the learning of new MAC addresses, which is useful because port security allows the number of devices that are connected to a particular switch port to be limited.
