Instructions


This article explains how Link Aggregation Groups (LAGs) are implemented on Dell Networking Force10 Switches.

 

Options for LAG type

 

  • Static
  • Link Aggregation Control Protocol (LACP)


Example of Static LAG


 

Command

Purpose

ftos#configure

Enter configuration mode.

ftos(conf)#interface port-channel 1

Define the port-channel number.

ftos(conf-if-po-1)#channel member te 0/1 - 4

Set the range of physical ports needed in the port channel.  Command requires a space between the numbers and hyphen.

ftos(conf-if-po-1)#no shutdown

Set Admin mode to up on the port channel.


 

Example of LACP LAG



LACP Modes

 

  • Active -- In this state, the interface is said to be in the "active negotiating state." LACP runs on any link that is configured to be in this state. A port in Active state automatically initiates negotiations with other ports by initiating LACP packets.
  • Passive -- Passive — In this state, the interface is not in an active negotiating state, but LACP runs on the link. A port in Passive state responds to negotiation requests from ports in Active state. Ports in Passive state respond to LACP packets.

     

Command

Purpose

ftos# configure

Enter configuration mode.

ftos(conf)# interface range te 0/1 - 4

Enter the range of physical ports needed for the port channel.  Command requires a space between the numbers and hyphen.

ftos(conf-inf-range-gi0/0-3)# no shutdown

Set Admin mode to up on the port.

ftos(conf-inf-range-gi0/0-3)# port-channel-protocol lacp

Enter port channel protocol type LACP.

ftos(conf-inf-range-gi0/0-3-lacp)#port-channel 1 mode [active | passive]

Define the port-channel number and mode.


 

Verification & Monitoring commands
