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.

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
