Nortel has released software 5.1.1 for the Ethernet Routing Switch 8600. Here some the SMLT/IST fixes from the release notes;

  • In RSMLT edge support enabled mode, the creation of a new RSMLT enabled VLAN interface only on one aggregation box will no longer cause the static default route to get deleted from the hardware, and thereby affect RSMLT forwarding and re-convergence time. (Q02005454-02)
  • In a dual SF/CPU configuration, when the last CP card is pulled out or fails, the RS I/O modules will now have their entire ports drop link automatically. This will help in any SMLT designed network to provide better and faster recovery. (Q01991517-02)
  • The ERS 8600 will now check for the SMLT status of an MLT only if it is configured as an SMLT, while sending a MAC-address-learn message for any MAC learnt on the MLT. If the MLT is not configured for SMLT, then SMLT status will not be checked and an MAC-address-learn message will be sent to the IST peer. (Q02036964)
  • 8600 will now update the ARP when a MAC learn message is received from IST peer, irrespective of whether the MAC is already existing as local or not. This reduces the chances of improper forwarding in SMLT/RSMLT designed networks. (Q02044582)
