5200 Great America Parkway Santa Clara, California 95014 (408) 878-6500 CUSTOMER RELEASE NOTES Issues Resolved in Version 3.1.1.0 I.D. LS-NAT Pinger - it appears that with load balancing, using UDP and the IP-Hash algorithm, the pinger function does mark servers out of service when they are unavailable. The load balancing task will continue to map connections to servers that are configured in the router but have no network connection.

5200 Great America Parkway Santa Clara, California 95014 (408) 878-6500 CUSTOMER RELEASE NOTES Issues Resolved in Version 3.1.0.9 I.D. POS - POS ports (as all other WAN ports) default to a point-to-point configuration, sometimes referred to as router-encapsulated links. Whenever there are MAC based ports (e.g. et., gi) in the same VLAN with non-MAC based ports (e.g.

5200 Great America Parkway Santa Clara, California 95014 (408) 878-6500 CUSTOMER RELEASE NOTES Issues Resolved in Version 3.1.0.7 I.D. Port Mirror - If port mirroring is enabled or disabled, and certain type of multicast traffic is being forwarded by the SSR, at that time, all of the first ports (number 1) stop passing IP Unicast traffic. This was checked on version 3.0 up to 3.1.0.4, this problem has now been corrected. Issues Resolved in Version 3.1.0.6 11073 I.D.

5200 Great America Parkway Santa Clara, California 95014 (408) 878-6500 CUSTOMER RELEASE NOTES Issues Resolved in Version 3.1.0.5 I.D. Directed Broadcast - Linux PCs will source IP address of 0.0.0.0 when making DHCP requests. If their DHCP request is not satisfied, they tend to continue to attempt a tftp for their config. With this address they should not be able to get across the router, but they do. This problem has now been corrected.

5200 Great America Parkway Santa Clara, California 95014 (408) 878-6500 CUSTOMER RELEASE NOTES Issues Resolved in Version 3.1.0.4 I.D. Stats - "statistics show ip-interface" and "statistics show ipx-interface" display the number of frames received on their ports. These statistics now show the number of packets for the individual interfaces. Issues Resolved in Version 3.1.0.3 07585 I.D.

5200 Great America Parkway Santa Clara, California 95014 (408) 878-6500 CUSTOMER RELEASE NOTES Issues Resolved in Version 3.1.0.3 I.D. OCMAC driver - The new OCMAC / SIPP - a port configured with a VLAN with id 4 through 7 can not bridge l2 traffic. The same results were observed on the gigabit card with OCMAC and SIPP. This problem does not exist on the older cards. This has now been resolved.

Please refer to the Hardware Requirements Table for hardware that supports this feature.

5200 Great America Parkway Santa Clara, California 95014 (408) 878-6500 CUSTOMER RELEASE NOTES ATM Module When configuring the Clocking on an ATM port, ensure that at least one end of the link is configured with local clocking. Most of the time the SSR will accept clock from an external source, so it can work with the default (local) clock. The SSR only supports internal and loop clock. 08066 A System core dump occurs while negating ATM configurations when an ATM module is not in the system.

5200 Great America Parkway Santa Clara, California 95014 (408) 878-6500 CUSTOMER RELEASE NOTES SSR 2000 SSR 2000 (SSR-2-B or SSR-2-B-AA) is not supported in this firmware release. Users with SSR-2-B or SSR-2-B-AA should NOT run this firmware image. Firmware 3.1 will not run in SSR-2-B or SSR-2-B-AA. The following system error message is reported when 3.1 is being run in a SSR-2-B or SSR-2-B-AA: Insufficient system memory to run this firmware image.

5200 Great America Parkway Santa Clara, California 95014 (408) 878-6500 CUSTOMER RELEASE NOTES Bridging Under some circumstances, SNA/DLC/NetBIOS traffic is not properly bridged across the SSR. The issue in bridging DLC packets occurs where the length field within an IEEE 802.3 frame indicates less than 46 bytes of data. The SSR removes the length field information of incoming IEEE 802.3, 802.2, and Ethernet_Snap packets and recalculates the field prior to retransmission.

5200 Great America Parkway Santa Clara, California 95014 (408) 878-6500 CUSTOMER RELEASE NOTES DVMRP A multicast packet is replicated to only one IP VLAN in an 802.1Q trunk port. Instead of an 802.1Q trunk port, use an access routed interface to forward multicast packets between two SSRs. Negating "dvmrp start" will cause memory leakage. 08249 Flashing LED When auto-negotiation is disabled on the gigabit ports, the LEDs may briefly flash on.

5200 Great America Parkway Santa Clara, California 95014 (408) 878-6500 CUSTOMER RELEASE NOTES Point to Point Protocol (PPP) When creating an IP interface on a VLAN with a single PPP port configured it should be set to “type point-topoint”. 07757 Port Statistics The statistics show port-stats command does not reflect correct one-minute traffic rates. The Frame count for layer-2 MAC broadcast frames in the port statistics menu is incorrectly counted twice.

5200 Great America Parkway Santa Clara, California 95014 (408) 878-6500 CUSTOMER RELEASE NOTES SmartTRUNKs When Spanning Tree Protocol (STP) is enabled on a SmartTRUNK, one link in the SmartTRUNK participates in STP. If you use STP with a SmartTRUNK that consists of ports of the same type, Cabletron Systems recommends that the ports in the SmartTRUNK be neighbors (i.e., in consecutive order) on the same line card.

5200 Great America Parkway Santa Clara, California 95014 (408) 878-6500 CUSTOMER RELEASE NOTES STATISTICS SHOW SUMMARY-STATS The output for the “statistics show summary-stats” command provides erroneous information for 5-minute and 15-minute summaries until the system uptime exceeds these time intervals. System CLI commands cannot be executed if a Telnet session is started through rsh from a UNIX system. Updating and erasing the system firmware image should not be done simultaneously.

5200 Great America Parkway Santa Clara, California 95014 (408) 878-6500 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.
