You connect an FC link to unified port 1/31 on a new Cisco Nexus 5548UP switch and receive the following error messages:
ERROR: Ethernet range starts from first port of the module ERROR: FC range should end on last port of the module
- The link you connected should have been to unified port 1/32.
- The link you connected was actually Ethernet, not FC.
- The link you connected should have been to unified port 1/17.
- The link you connected was FC but should have been Ethernet.
- The link you connected should have been to unified port 1/1.
Of the available choices, it is most likely that the link you connected should have been to unified port 1/32 on the Cisco Nexus 5548UP switch in this scenario. Unified ports are ports that can be either Ethernet or Fibre Channel (FC) ports. Cisco Nexus switches that support unified ports require that Ethernet links be connected from the beginning of the port range forward and that FC links be connected from the end of the port range backward. Slot 1 of a Cisco Nexus 5548UP switch contains 32 unified ports. Therefore, in this scenario, the FC link on the new switch would need to be connected to port 1/32 before any other FC links could be connected in the FC range.
As a further example, if you were to connect a single Ethernet link and a single FC link to slot 1 of a Cisco Nexus 5548UP switch that has no other links connected, you must connect the Ethernet link to port 1/1 and the FC link to port 1/32. If you were to then connect an additional Ethernet link to slot 1, that link must be connected to port 1/2. If you were to connect an additional FC link to slot 1, that link must be connected to port 1/31. Link additions should continue in that way until the Ethernet range ends where the FC range begins and no more ports are available in the slot.
The link in this scenario should not have been connected to unified port 1/17. Unified port 1/17 on a Cisco Nexus 5548UP switch falls in the middle of the 32-port range of slot 1. This port could be the end of an Ethernet port range if it were preceded by 16 other Ethernet links or the beginning of an FC port range if it were succeeded by 15 other FC links.
The link in this scenario should not have been connected to unified port 1/1. In addition, there is nothing in this scenario to indicate that the link was or should have been an Ethernet link.
