• The diagnostics application is capable of detecting insertion or removal of both the QSA as well as the SFP+ or SFP optical
cables plugged into the QSA. In addition, the diagnostic application is also capable of reading the DDS and Vendor information
from the EEPROM corresponding to SFP+ or SFP optical cables. As a result, no separate detection of QSA is required.
Support for LM4 Optics
The newly supported LM4 optics are similar in behavior to the LR4 optics that are already supported. However, in the output of
show inventory media command, an LM4 optical module is denoted as 40G-LM4. Barring this exception, the functionality and
behavior of LM4 optics is similar to LR4 optics.
Example Scenarios
Consider the following scenarios:
• QSFP port 0 is connected to a QSA with SFP+ optical cables plugged in.
• QSFP port 4 is connected to a QSA with SFP optical cables plugged in.
• QSFP port 8 in fanned-out mode is plugged in with QSFP optical cables.
• QSFP port 12 in 40 G mode is plugged in with QSFP optical cables.
For these congurations, the following examples show the command output that the show interfaces
tengigbitethernet transceiver, show interfaces tengigbitethernet, and show inventory media
commands displays:
