Trunks (link aggregation)¶
A trunk bonds two or more ports into one logical interface, for bandwidth or redundancy.
Where: Connectivity > Interfaces & network > Interfaces & network tab > + Add Interface > Trunk.
Creating a trunk¶
| Field | Meaning |
|---|---|
| Name | e.g. trunk0 |
| Protocol | LACP (802.3ad) or Failover (active/backup) |
| Member Interfaces (min. 2) | The ports to bond |
| Description | Optional label |
Click Create Trunk, then edit the trunk to give it addresses, or build VLANs on it. Member ports should carry no addresses of their own.
Choosing a protocol¶
| Protocol | Use when |
|---|---|
| LACP (802.3ad) | The switch has a matching LACP group on exactly these ports |
| Failover (active/backup) | You want redundancy without touching the switch |
Configure the switch before LACP
If the switch ports are not in a matching aggregation group, the trunk will not come up, and you can lose remote access to the gateway. Configure the switch first, or use Failover.
Checking it¶
The table shows the trunk's status; the port diagram still shows each member's link, which is how you spot a member that has lost its cable.
