NVRAM

Problems Fixed in
v3.0.5 Address Table
The following requests now return correct and complete values for the
9-port 1000BASE-SX Gigabit Ethernet Layer 2 Switching Module:
The value of entPhysicalVendorType that is returned for the
instance of the module itself (entPhysicalVendorType.4) now
contains the correct description.
The value of entPhysicalDescr that is returned for the module now
contains slot, subslot, and revision numbers as it should.
Port Monitor Mode and Resilient Link Port configuration is properly
initialized when upgrading a 36-port Layer 2 Switching Module from
software release 2.x to release 3.0 or 3.0.5. (30432)
The "instability" issue caused by TCMP messages not being processed
properly in MPLA configurations, has been fixed. Stimulus such as
Address Table MIB walks, or Address Tracker application queries, on any
of the v3.0.0 devices had caused a problem where other "high
availability" features would be forced to adjust as a reaction to
unprocessed TCMP messages. MPLA with TCMP configurations and
allClosed VLANs had problems in this area.
The problem with SNMP GetNext commands not being processed
properly has been partially fixed, such that MAC addresses now return
upon command from the CLI and MIB walk queries. However, general
response time to these queries is slow due to the limitations of the ASIC
and various processes vying for shared resources.

Problem Overview

If SNMP tools like SNMX or GetMany (Jeff Case Tools), are used to
execute address table MIB walks against v3.0.5 code, these requests will
time out at times and not return all MAC addresses requested. The
Transcend Address Tracker application exacerbates this condition and
causes traffic to slowdown, which is recoverable once Address Tracker
query processes are shut down.
Manual requests (from the CLI or Web interfaces) and non-automated
requests do not cause this problem. MAC addresses are returned
smoothly from requests from the CLI or Web interface.
