6.5.2. Administrative and Operational Port Map
(BZ#: 4357)
Description: Any changes to the port map while operating the EM316DMR3G-3R in Redundant
Mode will only apply to the administrative port map, not the operational map. The administrative port
map and changes made to it will become the operational port map when switching out of redundant mode
to repeater mode.
Suggested Work-Around: None.
Customer Impact: Moderate : This feature is not supported, but basic functionality is there.
Corrective Action: No change to design. This feature works as designed.
6.5.3. Lin and Port Map
(BZ#: 4356)
Description: When LIN is enabled, the EM316DMR3G-3R module will lose its current port map pair
when one of the corresponding ports is disconnected. The disconnected port and its corresponding mapped
port is the only pair affected. Once the port is reconnected and establishes a valid link, the port map returns.
The symptom described in the above paragraph is due to the inherent flaw in the module design that a
'disabled port' has 'no mapping'. In other words, 'cleared mapping' implies 'disabled port'. Please note that
when LIN engine works, it ends up disabling ports administratively/automatically.
Suggested Work-Around: None.
Customer Impact: Moderate: feature does not appear to behave as expected, however basic
functionality is not affected.
Corrective Action: This issue will be addressed in future software upgrades.
6.5.4. FDDI Protocol Display
(BZ#: 718,4345)
Description: The protocol "FDDI" can be set using the CLI port protocol command. However, it will
not be displayed that is has been set when using the show command. Instead it will be reported that the
port has been set to "Fast Ethernet".
Suggested Work-Around: Use show config to display the protocol setting for the port in
question.
Customer Impact: Minimal. Informational only.
Corrective Action: This issue will be addressed in future software upgrades.
