Configure Interfaces and Port Channel
This section provides the commands for configuring port channels on common upstream switches that are
connected to the FN IOM system.
The previous illustration is applicable to the FN 410S and FN 410T servers. If you are using the FN 2210S server
in its default configuration, you can only use the TenGigabitethernet 0/11 and TenGigabitethernet 0/12 in the
uplink port channel. Ports TenGigabitethernet 0/9 and TenGigabitethernet 0/10 are Fibre Channel ports.
By default on the FN IOM, the external Ethernet ports are preconfigured 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 configured 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 configures a port channel on an upstream switch:
• No configuration is required on the FN IOM system. All configurations are done on the upstream switch.
• In the example, four interfaces are configured in the port channel. Configure 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.
Dell(conf)#interface range tengigabitethernet 0/1-4
Dell(conf-if-te-0/1)#no shut
Dell(conf-if-te-0/1)#port-channel-protocol lacp
Dell(conf-if-te-0/1-lacp)#port-channel 128 mode active
Dell(conf)#interface port-channel 128
Dell(conf-if-po-128)#portmode hybrid
Dell(conf-if-po-128)#switchport
Dell(conf-if-po-128)#no shut
Verifying the Configurations
When the port channel of the upstream switch is configured, 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.
