Avaya has released software 6.2.3 for the Ethernet Routing Switch 5500/5600 series switches.
Here are some of the highlights from skimming the release notes;
- SLPP Guard
The Switch Clustering implementations on the VSP9000, ERS8800/8600, and ERS5000 provide a Simple Loop Prevention Protocol (SLPP) packet, which operates to help prevent loops from occurring when Switch Clustering is used.
Simple Loop Prevention Protocol (SLPP) Guard can be used to provide additional loop protection to protect wiring closets from incorrect or faulty connections. When SLPP Guard is enabled, this loop prevention mechanism extends into and across multiple wiring closets. If an edge switch configured for SLPP Guard receives an SLPP packet on a port, the feature can immediately disable the port administratively, and generate appropriate log messages and SNMP traps.
The following issues were resolved in this release;
- Stack upgrade failure from 6.1.4.011s to 6.2.1.003s with a large config file (wi00882592)
- Loss of IST VLAN on three unit stack after a base unit failure (wi00885609)
- Some links get disabled after upgrade from 5.1.x to 6.x (wi00731564)
- IST Peers FDB table were out of sync (wi00892974)
- “show spanning-tree rstp port role” command displayed ‘Oper Status’ incorrectly as “disabled” after reboot (wi00899325)
- After upgrading from 5.1.4 to 6.2.1 EDM routing/IGMP/SNOOPING table expanded indefinitely causing high CPU utilization (wi00886347)
- Using show running-configuration with 744 VLANs configured, spiked the CPU utilization to 100% for about 12-15 minutes (wi00907462)
