5720-VIM-6YE adds LRM support using an LRM/MACsec adapter, part 10965. The adapter includes two SFP+ host ports and two SFP/SFP+ network/link ports. Host ports use a proprietary 10 Gbps direct attach cable (DAC) to connect to the host (5720-VIM-6YE). You must connect both host ports to trigger PHY initialization and you must insert the DAC in the adapter before you insert the DAC in the VIM.
Both host ports and an auxiliary USB port provide power to the adapter. As a best practice, always use the USB port to provide power.
This release includes new CLI commands to upgrade the internal PHY firmware for the adapter and to view the firmware status.
Note
MACsec functionality of the adapter is not supported, with no impact on MACsec support of the VIM itself.
For more information, see Two-Port External LRM/MACsec Adapter. For the new CLI commands, see Fabric Engine CLI Commands Reference or Fabric Engine User Guide.
