Before connecting switches in a loop, it is highly recommended that spanning tree be enabled on all switches.

This guide provides examples and commands for configuring spanning tree on the N-Series switches when

connecting to a Cisco Catalyst. Refer to the spanning tree sections of this document or consult the User’s

Guide for each switch for more information on configuring spanning tree.

2.4.1 Configuring Multiple LAGs — Dell N-Series

This section covers setting up an additional port channel on an N3024 switch. The commands below can be

used on either N3024 switch in the above topology to configure port channel 8 as a trunk going between each

Dell N-Series switch. As a best practice, a description is then placed on the port. The 10 Gbps Ethernet ports

te1/0/3 and te1/0/4 are joined to port channel 8 and LACP is enabled through the use of active. A show

command is used to show the status of the port channel and verify interface participation.

N3024#configure

N3024(config)#interface port-channel 8

N3024(config-if-Po8)#switchport mode trunk

N3024(config-if-Po8)#description "LAG to Dell N3024-2"

N3024(config-if-Po8)#exit
