Moving the question to this forum area as more appropriate.

See initial thread started here.

 

yes.

Yes, Unraid's Ethernet bonding can be configured to work with Cisco switch Link Aggregation (LAG) using LACP (802.3ad). Here's how to set it up

more info here:

 

Essential Unraid Configuration for LACP:
1 Access Network Settings: In Unraid, navigate to Settings > Network Settings.

2 Select Interfaces to Bond: Choose the network interfaces (e.g., eth0 and eth1) you wish to bond.

 

3 Enable Bonding: Set bonding to "Yes" and select bonding mode 802.3ad (LACP).

4 Apply Settings: Save and apply the changes.


Then cisco switch post config... On your Cisco switch:

1. Create a Port Channel: Define a port channel and assign the physical interfaces (e.g., GigabitEthernet0/1 and GigabitEthernet0/2) to it.

2. Enable LACP: Set the port channel mode to active to enable LACP.

3. Configure VLANs (if applicable): If you're using VLANs, ensure they are properly configured on the port channel.

 

example:

interface Port-channel1
  switchport mode trunk
  switchport trunk allowed vlan [your VLANs]
  channel-group 1 mode active

interface GigabitEthernet0/1
  switchport mode trunk
  channel-group 1 mode active

interface GigabitEthernet0/2
  switchport mode trunk
  channel-group 1 mode active

 

@bmartino1 thank you! In my case with the SG200, it is very similar, but some of the names are different. For anyone else with a Cisco SG200 or similar:

From Port Management / Link Aggregation / LAG Management: Select the LAG you want to use (1 to 4), click Edit. Add the ports from the Port List to the LAG Members list with the > arrow button. Be sure to check the "LACP Enable" box. I chose IP/MAC address for load balance. Give the LAG a name. Click Apply and Close.

From Port Management / Link Aggregation / LAG Settings: Additional settings are available - I didn't need to change any of them.

 

From switch saved configuration:

interface gigabitethernet25
 description "T440 Server Eth1 Bonded"
 channel-group 1 mode auto
!
interface gigabitethernet26
 description "T440 Server Eth2 Bonded"
 channel-group 1 mode auto
!
interface Port-channel1
 flowcontrol auto
 description T440-LAG
!

 

In Unraid, Ethernet: Enable Bonding Yes, Bonding Mode 802.3ad(4), bonding members eth0, eth1, Enable bridging Yes

 

To verify, I ran two instances of iperf3 server in Unraid from SSH shell sessions. (Use an alternate port for the second one)

Run iperf3 clients to the unraid server's IP (different ports) from two different computers at the same time.

On the Unraid dashboard for interface bond0, you should see an inbound number over 1 Gbps. I saw 1.9 Gbps with both iperf clients running.
