======================================================================== Nortel Networks, Inc Updated: 10/29/98 Model 28115, BayStack 28115/ADV, BayStack 28104/ADV Verion 2.0.4.2 ======================================================================== RELEASE SUMMARY: =============== This is a REV release. This release has incorporated bug fixes and feature enhancement after version 2.0.4.1. PLATFORMS SUPPORTED: =================== 28115, 28115/ADV, 28104/ADV NOTES FOR UPGRADE: ================= VERSION OF PREVIOUS RELEASES: Verion 2.0.4 Date: 7/98 Version 2.0.4.1 Date: 8/98 COMPATIBILITY: ============= FEATURES IN THIS RELEASE: ======================== 1. Multicast Outbound Filter: This feature is designed to run in spanning tree mode only. It provides the user the ability to direct multicast traffic according to the needs of the network application. The multicast filter is configured by going to the following menu: Configuration Parameters->Switch Parameters->Modify Multicast Steering Feature Multicast Steering Configuration Multicast Filtering Feature [Enabled] Multicast Address [01003c6b181e] Destination Port List 1 [17,18] Source Port List 1 [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16] Destination Port List 2 [1] Source Port List 2 [17] Destination Port List 3 [] Source Port List 3 [] Destination Port List 4 [] Source Port List 4 [] Description of parameters: Multicast Filtering Feature [Enabled/Disabled] - Enables/disables this feature. When this option is selected, a "Confirm ? (y/n)" prompt will ask for confirmation. Enter a "y" to enable these filters or "n" to disable the filters. Multicast Address - The address that the user want to filter on. This address is specified as a single string, so if the multicast address that the user wish to filter on is 01 00 3c 6b 18 1e (hex), enter "01003c6b181e" at the prompt. Destination Port List 1 Source Port List 1 Destination Port List 2 Source Port List 2 Destination Port List 3 Source Port List 3 Destination Port List 4 Source Port List 4 - The port lists that the user want to filter on. For lists with more than one port, specify the list of ports separated with commas. For example, for a list containing 2,4,7,10, enter "2,4,7,10" To clear out the list, enter "0" Multicast filtering works by specifying lists of destination and source ports that the user want the traffic to go to and from. So, for example, if the user want the traffic to go from port 1 to port 2, in Destination Port List 1, enter "2" and Source Port List 1 enter "1". Up to three lists are provided so that the user can have flexibility with the filter definitions. This is useful when requiring three different lists of source ports directing traffic to different destinations. This code is port state sensitive, so ports in blocking mode will not forward packets with filters on them. Characteristics of the feature: 1) Overlaps in source port definitions will be resolved in reverse order. For example, if port 4 is defined in port list 1 to forward to port 2 and it is also defined in port list 2 to forward to port 3, then port 4 will forward to port 3.The last port list definition takes precedence. 2) The software does not check input for logic problems, ie intentionally inserting loops. 3) Filters will take about 30 seconds to enable on bootup or topology change due to spanning tree. Check the Trace Log for the message "TopoStable" to know if filters are applied when there is a topology change. 2. Ability to turn off the pinging of the default router Since release 2.0.1, the 281xx pings the default router. This characteristics did not exist in release 1.4.2. In this release, there is an option to allow users to turn the pinging off from the debug menu. debug menu -> system -> "pinging to the Default Router" Features added in 2.0.4 release: 1. IP connectivity debug feature is added in this release. OLD FEATURES REMOVED IN THIS RELEASE: ==================================== Features removed from 2.0.4.1 release: 1. The IP connectivity debug feature has been removed. PROBLEMS RESOLVED IN THIS RELEASE: ================================= CR 57156: Cisco HSRP The Cisco HSRP enhancement in the 2.0.3 release interfered with the forwarding of HSRP frames to other devices on the network. CR 71452: Cisco HSRP Over a Trunk link between two 281xx, 58000 or 28200 switches, only the UMAC address from the HSRP protocol is learned but not the HSRP VMAC address. CR 51554: Topology For previous releases, when a TCN is detected, all ports will go into config mode. In this release, only particular port goes into config mode when a TCN has been detected, not the whole switch. CR 57647: Spanning Tree In previous versions of 2.0.x, when the primary path in Spanning Tree is lost, connectivity to the secondary link cannot be established until a broadcast frame is sent from the source. In this release, the Macstore of a port will be flushed when it changes from root port into non root port. CR 71054: MIB In previous versions when performing a MIB II query on interfaces.ifTable.ifEntry.ifInOctets, the switch returns invalid counts. CR 57336 Diagnostics Older versions of 28K I/O modules fails power up diagnostics loopback test intermittently. CR 57059 Expansion Port In previous 2.0.x releases, the 281xx expansion port will stop forwarding traffic, if the port is preconfigured to something other than 200mbps full duplex. PROBLEMS RESOLVED IN PREVIOUS RELEASES: ====================================== Problems resolved in 2.0.4 release: CR 72713 TRAP Trap Receiver table is not aging out CR 57110 Year 2000 Compliance fix.
