Dell OS10 Port-Channel Configuration: LACP Step-by-Step

2026年8月25日 LOG admin

Link aggregation is the foundation of resilient switch-to-switch and switch-to-server connectivity, and on Dell PowerSwitch S-series hardware running SmartFabric OS10 the process is refreshingly straightforward. This article walks through the official Dell Technologies procedure for configuring port-channels with LACP, covering static versus dynamic channels, the exact CLI sequence, and the verification commands that confirm your aggregated link is healthy. Following these steps will let you double your inter-switch bandwidth while eliminating single points of failure in the data path.

Port-Channel Basics: Static vs. Dynamic (LACP)

Port-channels on OS10 can be static or dynamic. Dynamic port-channels are configured using the Link Aggregation Control Protocol (LACP) and operate in one of two modes:

Active - the interface is placed in the Active Negotiation state; an active port can form a port-channel with another port in Active or Passive mode.
Passive - the interface is in the Inactive Negotiating state, but LACP still runs on the link; a passive port responds to active negotiation requests but will never initiate a channel with another passive port.

Prerequisites and Topology

For this example, switch #1 and switch #2 exist with two links between them on ports 1/1/33 and 1/1/34. Both switches must be reachable via console or management IP, and you log in with the default OS10 credentials (user admin, password admin).

Step-by-Step OS10 Port-Channel Configuration

Step 1: Enter Global Configuration Mode

OS10# configure terminal
OS10(config)#

Step 2: Create Port-Channel 1

OS10(config)# interface port-channel 1
OS10(conf-if-po-1)# exit
OS10(config)#

Step 3: Select the Member Interfaces

OS10(config)# interface range ethernet 1/1/33-1/1/34
OS10(conf-range-eth1/1/33-1/1/1/34)#

Step 4: Add Members with Active LACP

OS10(conf-range-eth1/1/33-1/1/1/34)# channel-group 1 mode active
OS10(conf-range-eth1/1/33-1/1/1/34)# end
OS10#

Repeat the same procedure on switch #2. Using mode active on both ends ensures LACP negotiation completes and both links bundle into a single logical channel.

Verifying the Port-Channel

Confirm the configuration with:

OS10# show interface port-channel summary

Check LACP state and counters with show lacp and show lacp port-channel 1. The channel members should show an Up/Up state with LACP in the Bundled or Collected state. Remember to save your work with write memory so the configuration survives a reload.
