DELL N3000 User Manual

Configuring Link Aggregation

The following example configures eight VLANs (10–17) across two VPCs. 

VPC 1 is connected to an N2048 over two links (gi1/0/23-24) over port-

channel 2 on each MLAG peer. Interfaces Te1/0/1-2 on each MLAG peer 

connect to each other on port-channel 1 utilizing LACP. UDLD is enabled on 

the two MLAG peer-links and the timers are configured to the minimum 

values. DCPDP is enabled on routed VLAN 100 (interface gi1/0/8 on each 

MLAG peer). VLAN 100 is excluded from any MLAG interface, including the 

peer-link.
VPC 2 is connected to a legacy Cisco 3750 over port-channel 3 on each 

MLAG peer, and is also running LACP. The Cisco configuration is shown for 

completeness.
Spanning tree instance 0 is configured for VLAN 1. Spanning tree instance 1 

is configured for VLANs 10–17. The Cisco 3750 acts as the root bridge for the 

topology.
