By default on the FN IOM, the external Ethernet ports are precongured in port channel 128 with LACP enabled. Port channel 128 is in
hybrid (trunk) mode.
To bring up the downstream (server) ports on the FN IOM, port channel 128 must be up. When the Port channel 128 is up, it is connected
to a congured port channel on an upstream switch. To enable the Port channel 128, connect any combination of the FN IOM’s external
Ethernet ports (ports TenGigabitethernet 0/9-12) to the upstream switch. The port channel may have a minimum of one and a maximum of
four links.
Following example congures a port channel on an upstream switch:
• No conguration is required on the FN IOM system. All congurations are done on the upstream switch.
• In the example, four interfaces are congured in the port channel. Congure as many interfaces as you have connected. Change the
port numbers to match your switch.
• Any valid ID number can be used for the port channel number on the upstream switch.

Verifying the Congurations
When the port channel of the upstream switch is congured, the port channel on the FN IOM is up. A series of messages is logged on the
system indicating port channel 128 and the ports connected to the servers downstream are up.
Changed interface state to up: Po 128
Downstream interface cleared from UFD error-disabled: Te 0/1
Downstream interface cleared from UFD error-disabled: Te 0/2
Downstream interface cleared from UFD error-disabled: Te 0/3
…etc.
To verify the status, run the following commands:
Dell#show interfaces port-channel 128
Port-channel 128 is up, line protocol is up
Dell#show uplink-state-group
Uplink State Group: 1 Status: Enabled, Up
