35 Industrial Way PO Box 5005 Rochester, NH 03867-5005 (603) 332-9400 CUSTOMER RELEASE NOTES Per VLAN Spanning Tree (Spanning Forest) Release 3.0 implements Spanning Tree per VLAN (also called Spanning Forest). A separate instance of Spanning Tree can be run per VLAN. On initialization, the SSR runs one spanning tree instance, which is called the default spanning tree (Note that this is backward compatible with pre-3.0 releases).
35 Industrial Way PO Box 5005 Rochester, NH 03867-5005 (603) 332-9400 CUSTOMER RELEASE NOTES Transparent Web Cache Redirect The web cache redirect feature on the SSR works in conjunction with a cache server to store commonly accessed HTTP objects locally on the cache server. This results in substantial cost savings by saving on WAN access costs and increasing the response time tremendously. This feature offers redundancy and load sharing capabilities for building high availability cache server farms.

35 Industrial Way PO Box 5005 Rochester, NH 03867-5005 (603) 332-9400 CUSTOMER RELEASE NOTES Issues Resolved in Version 3.0.1.0 I.D. There have been problems accessing SSR MIBs from the SPEL MIB browser. In updating some of the supported MIB information, the agent instrumentation layer was not properly hooked up when the MIBs were changed. This issue has now been corrected. 08084 The NetScout RMON II application couldn’t retrieve data from pprotocolDistStatsTable using the Get operator.
35 Industrial Way PO Box 5005 Rochester, NH 03867-5005 (603) 332-9400 CUSTOMER RELEASE NOTES Issues Resolved in Version 3.0.1.0 I.D. Using SPEL - SNMP poll on the interface index (ifindex) caused the SSR to crash. Modifications to the interface index have been made to correct this problem. Multicast QoS specified with interface did not function properly. When a multicast QoS priority profile was defined for an interface, the multicast flow did not get the correct priority. This has now been corrected.
35 Industrial Way PO Box 5005 Rochester, NH 03867-5005 (603) 332-9400 CUSTOMER RELEASE NOTES Issues Resolved in Version 3.0.1.0 I.D. Within an LMI, the status for VCs 0 & 1023 should be disregarded. Generally, the network will not give status on these VCs since they are reserved for signaling. This problem has been corrected. 07315 In some instances, packets were getting dropped over frame-relay circuits, this was due to a Frame Checksum Error. This problem has been corrected.
35 Industrial Way PO Box 5005 Rochester, NH 03867-5005 (603) 332-9400 CUSTOMER RELEASE NOTES Issues Resolved in Version 3.0.1.0 I.D. When auto-negotiation was disabled on a gigabit port and no link was established, the red LED would flash intermittently. This behavior has been corrected. 06639 In some cases the SSR-2000 would hang during manufacturing diagnostics - this problem was usually experienced during flash write operations. This problem has been corrected.
35 Industrial Way PO Box 5005 Rochester, NH 03867-5005 (603) 332-9400 CUSTOMER RELEASE NOTES 100Base-TX Module In some instances, if a 100Base-TX module is configured to auto negotiate, link failure may occur due to incorrect implementation of the auto negotiation feature by the device. The workaround is to manually set the port speed and duplex settings on the SSR. Control Module If you are using an SSR-CM2-64/128 Control Module, you must place the PCMCIA flash card in slot0.
35 Industrial Way PO Box 5005 Rochester, NH 03867-5005 (603) 332-9400 CUSTOMER RELEASE NOTES Telnet During the telnet session, if the "Ip show routes" command is executed, on and SSR with a large number of entries in the Routing Information Base, the SSR might crash. This issue will be addressed in the next release of the firmware. 802.1Q If a trunk port is created, the port is changed from access to trunk, but is not automatically added to any VLAN.
35 Industrial Way PO Box 5005 Rochester, NH 03867-5005 (603) 332-9400 CUSTOMER RELEASE NOTES CPU Redundancy You cannot hot swap an active Control Module without pressing the HotSwap button or operating through the console. Doing so will cause the SSR to crash. If the backup Control Module fails to receive a heartbeat from the active Control Module for a certain interval (~60 seconds), the backup Control Module assumes the active Control Module’s role, including its MAC address.
35 Industrial Way PO Box 5005 Rochester, NH 03867-5005 (603) 332-9400 CUSTOMER RELEASE NOTES DVMRP If an interface that has DVMRP or IGMP enabled is deleted and added back again, DVMRP and IGMP do not detect it. The workaround is to restart DVMRP by executing the no dvmrp start command and committing the change, then executing the dvmrp start command and committing the change. DVMRP scope does not work in this current release of the firmware.
35 Industrial Way PO Box 5005 Rochester, NH 03867-5005 (603) 332-9400 CUSTOMER RELEASE NOTES IP Routing If there is a redistribute or export-related policy command in the configuration, such as the following: ip-router policy redistribute from-proto ospf to-proto rip then the default policies are superseded; that is, RIP and direct routes are no longer redistributed by default. To redistribute RIP and direct routes that would have been announced by default policies, you must explicitly redistribute them.
35 Industrial Way PO Box 5005 Rochester, NH 03867-5005 (603) 332-9400 CUSTOMER RELEASE NOTES Quality of Service (QoS) The interface name parameter, which is the last possible parameter when configuring an IPX QoS entry, does not work. Do not enter an interface name when configuring an IPX QoS entry. Certain L2 QoS configurations may not work when applied to a port set to flow-bridging mode. (The default setting for a port is address mode.
35 Industrial Way PO Box 5005 Rochester, NH 03867-5005 (603) 332-9400 CUSTOMER RELEASE NOTES SmartTRUNKs When a hotswap is performed on any card, the link for any SmartTrunk configured with huntgroup protocol goes down for a few seconds. If you hotswap a card that has SmartTrunk configured along with Layer 2 filters, then the SmartTrunk commands are marked with an "E". SNMP Get-next on the capMemoryTable returns no response, although the capMemoryTable has been traversed completely.
35 Industrial Way PO Box 5005 Rochester, NH 03867-5005 (603) 332-9400 CUSTOMER RELEASE NOTES SSR 8600 Firmware If you need to downgrade the SSR 8600’s system firmware from version 2.x.x.x code to version 1.2.x.x, make sure to power down the SSR and power up again before downgrading system firmware. If you do not do this, the SSR may not be operational, or you may see the following error message: SYS_ERR: Transmit queue full Additional information can be found in Technical Bulletin: http://www.cabletron.
35 Industrial Way PO Box 5005 Rochester, NH 03867-5005 (603) 332-9400 CUSTOMER RELEASE NOTES VLANs There are two special VLANs on the SSR, the Default VLAN (ID=1) and the VLAN with ID=4095. The Default VLAN contains all of the ports not used in other VLANs. When ports are added to VLANs, they are removed from the Default VLAN. When ports are removed from a VLAN with an ID other than 1, they are returned to the Default VLAN. The VLAN with the ID of 4095 (a.k.a.
35 Industrial Way PO Box 5005 Rochester, NH 03867-5005 (603) 332-9400 CUSTOMER RELEASE NOTES WAN Modules STP (Spanning Tree Protocol) per VLAN (PVST) is not supported on WAN ports. Packets do not flood WAN ports belonging to the Default VLAN. To allow flooding of packets, the WAN port should be added to a non-default VLAN. CoreWatch Software Information about CoreWatch is covered in a separate Release Note. The latest CoreWatch User’s Guide is located on the CoreWatch CD.

This problem occurred when an IP interface was created and RARP was disabled on that interface (the default condition) or if there was no mapping of the MAC address to an IP address in the RARP table.
