Dell OS10 Port-Channel Setup: LACP and Static LAG CLI

Dell PowerSwitch OS10 builds link aggregation through port-channels (also called LAGs). A port-channel can be statically configured with mode ON, or negotiated dynamically with the Link Aggregation Control Protocol (LACP) in active or passive mode. This walkthrough creates an LACP port-channel between two S-series switches, adds a VLAN to it, tunes LACP parameters and verifies the bundle with the exact OS10 show commands.

Static vs Dynamic Port-Channels on OS10

• Static (mode ON) — members are manually forced into the bundle; no negotiation frames are exchanged.
• LACP active — the port actively sends LACP PDUs and can peer with an active or passive partner.
• LACP passive — LACP runs on the link but only responds to an active partner; two passive ports never form a bundle.

OS10 LACP Port-Channel Configuration

Repeat the following on both switches. Create the logical port-channel first, then add the physical members with a range:

OS10# configure terminal
OS10(config)# interface port-channel 1
OS10(conf-if-po-1)# exit
OS10(config)# interface range ethernet 1/1/33-1/1/34
OS10(conf-range-eth1/1/33-1/1/34)# channel-group 1 mode active
OS10(conf-range-eth1/1/33-1/1/34)# no shutdown
OS10(conf-range-eth1/1/33-1/1/34)# end
OS10# write memory

For a static bundle, replace mode active with mode on. If the port-channel carries a specific VLAN, configure it in Layer 2 mode (the default on access interfaces) or make the member a trunk:

OS10(config)# interface port-channel 1
OS10(conf-if-po-1)# switchport access vlan 10
OS10(conf-if-po-1)# end

Verifying the OS10 Port-Channel

OS10# show interface port-channel summary
OS10# show interface port-channel 1
OS10# show lacp port-channel

A healthy LACP bundle shows both member ports Up with status L2. show lacp port-channel displays the actor and partner system IDs plus the negotiated keys — if the partner system ID is missing, the far end is not running LACP in a compatible mode.

Tuning LACP on OS10

When the remote switch has a lower system priority, it wins LACP decisions. Influence the outcome from global and interface configuration:

OS10(config)# lacp system-priority 4096
OS10(config)# interface range ethernet 1/1/33-1/1/34
OS10(conf-range-eth1/1/33-1/1/34)# lacp port-priority 100
OS10(conf-range-eth1/1/33-1/1/34)# lacp rate fast

Port-channels are the foundation of OS10 high availability. See our OS10 VLT peer-routing guide for active-active Layer 3 gateways, OS10 out-of-band management configuration for the management VRF, and compare the syntax with Arista EOS port-channel and LACP configuration.
