Nortel has released software 220.127.116.11 for the Ethernet Routing Switch 8600. Here some highlights from the release notes;
- Previously certain IST message handling could be delayed by other system functions, thereby potentially causing IST instability (up/down/up). As well, system instability associated with SMLT (IST Peers) in association with high CPU utilization and potentially SLPP operations have both now been resolved. For those who disabled SLPP on their systems/network, SLPP can now be re-enabled with the 18.104.22.168 release. (Q02055292-02/Q02053200/Q02055101/Q02066500)
- Static routes usage in a VRF configured system for non-default VRFs (non-VRF 0 usage) will no longer cause a spike in CPU utilization. Now even after reboot all the static routes will remain active and CPU utilization will remain normal. This situation was introduced in 22.214.171.124 code, so only applies to that specific release. (Q02060978-03)
- Previously unicast traffic could be flooded with the VLAN when some SMLT/RSMLT associated link failed; this is now resolved. (Q02037171)
There were two additional items of interest in the release notes that were included under the “Important Notes” section. The first reference the configuration of the system-monitor flag, it should be set in the enabled position and can only be set via SNMP by Nortel’s Java Device Manager (JDM) or by sending the proper SNMP command. The second item referenced a possible crash of the SNMP task within the 8600 software if the retry value for SNMP trap hosts was set greater than 0. I would suggest everyone reference the release notes for additinoal information on both of those items.
