Static Routes - Avaya ERS 8600 Manual


Reliability of R and RS series line card recovery after CPU resets (normally seen during switch software
upgrades) has been improved due to enhancements in SF/CPU to I/O module co-processor message
communication and synchronization. (Q02091485/ Q01997485)

ERS 8600 will no longer silently drop packets when the number of ACEs with debug count enabled is such that
system resources are at their maximum, but instead the filters will now all function properly. (Q02045086)

A memory corruption scenario has been identified which previously led to intermittent system instability and log
messages relating to data manipulations of the rarHashBin data structure in some environments (log messages
would contain RAR wording). The underlying cause of the memory corruption leading to the instabilities has
now been resolved. (Q02093533, Q02106560)
RSTP/MSTP

Enhanced MSTP/RSTP logging information which was previously added in release 4.1.3.0 was not present in
any 5.x code. This functionality has now been properly added. Q02053232)

The VLAN interface on an ERS8600 in RSTP/MSTP mode will no longer be brought up unless a port first
becomes active in the VLAN. This matches the existing VLAN interface behaviour in STP mode. (Q02083039)

Packet loss on an MLT with RSTP enabled will no longer been seen after a CPU reset/switchover with HA
mode enabled or after a complete switch re-boot. (Q02003158-01)

ERS 8600 will properly retain the MLT path-cost configuration over reboots when configured for RSTP/MSTP
mode. (Q02048253)

ERS8600 will now properly show the MSTP CIST port path cost info when "show port info mstp" is executed.
(Q02048252)
IP Unicast
UDP

The configured filter action is now properly observed for ACL's configured to match UDP source and
destination port ranges between 32752 and 32767. (Q02076252-01)

Static Routes


ERS 8600 will no longer encounter system (DRAM) memory exhaustion with DHCP-relay configured on a
Layer 2 VLAN or at the port level for a non-brouter port. (Q02076879)
BGP

ERS 8600 will now properly learn the default routes from eBGP peers even after the failover or toggling of
the physical port connection. (Q02094999)
IP Multicast

ERS 8600 will no longer observe periods of sustained high CPU utilization associated with the forwarding
of multicast traffic. (Q02067852)

ERS 8600 will now properly recover its DVMRP status for an ATM interface when a Port/Fiber Fault
occurs, and is then restored. (Q02041428)
