Expander Module
When the Fabric Switching Engine discovers the Fabric Expander, it creates virtual ports by mapping each 8x25GE FEM breakout
interface in port groups 1 to 9 to a Fabric Expander virtual port.

NOTE: In the show interface status output, the Fabric Switching Engine 8x25GE interfaces that map to Fabric
Expander virtual ports display as dormant.

You can also use the show interface command to display the Fabric Engine physical port-to-Fabric Expander
virtual port mapping, and the operational status of the line.
OS10# show interface ethernet 1/1/30:3
Ethernet 1/1/30:3 is up, line protocol is dormant
Interface is mapped to ethernet1/77/7
5. Verify the virtual ports on the Fabric Expander that are up and connected to servers in CONFIGURATION mode. Unit IDs 71 to 82 are
used as virtual slot numbers 1/71 to 1/82 on the Fabric Expander.

6. Configure a Fabric Expander virtual port to transmit server traffic in CONFIGURATION mode.
OS10# interface ethernet node/virtual-slot/port
node is 1 for a Fabric Expander.
virtual-slot is the unit ID number assigned to the Fabric Expander, from 71 to 82.
port is the virtual port number 1 to 8.
