Corrected Problems in Release 3.0.5
37
gathering agent will time out and not report any MAC addresses have
been returned by the EME.
Work Around
There is a work around for the issues of timing out while gathering MAC
addresses. That is, you must extend the timeout interval of the SNMP
gathering agent to allow for up to 15 seconds of delay when your
network is using high availability features such as VRRP and MPLA.
Unfortunately, the applications Transcend Address Tracker and Enterprise
VLAN Manager cannot modify their timeout intervals sufficiently to
accommodate the EME, which is the cause of an incomplete number of
MAC addresses returning to Address Tracker.
In some configurations involving MPLA and Closed VLANs, traffic may be
slowed altogether while querying the switch for MAC and IP addresses,
but the device and network do recover smoothly from these instances.
Stability issues have been fixed with respect to proper TCMP processing,
however the return of MAC addresses upon query in these configurations
is slow.
Recommendations
Follow the guidelines listed below for disabling background processes of
Transcend Address Tracker and Enterprise VLAN Manager if you do not
want to have these applications querying your network devices on the
default time interval.
Transcend applications within FR003 UNIX 5.0 update are supported with
software release 3.0.5. Transcend NT 1.2 applications are also supported
by software release 3.0.5.
Guidelines from FR003 TRANSCEND UNIX 5.0 UPDATE
The following known problem reference is from the Functional
Limitations section of the FR003S README file from JANUARY 2000
TRANSCEND UNIX 5.0 UPDATE RELEASE: General NMDww04250.
Some high-availability features from software release 3.0.0 including
MPLA, STP and VRRP, may become unstable when the associated packet
switching devices are polled by Enterprise VLAN Manager, Address
Tracker, and other applications that poll the bridge address MIB tables,
perform a MIB walk of the bridge address table, or use a command line
interface to retrieve bridge address table data.
