Outlines how to configure LACP in Qumulo Core
- Qumulo Core 2.1.5 to support 802.3ad LACP
- 2.5.3 and above where LACP is enabled by default
- Command line (CLI) tools installed via API & Tools tab
As of 2.1.5 we support 802.3ad LACP which enables bonding multiple network ports together into a single logical channel to increase available bandwidth to a Qumulo node. LACP 802.3ad can be enabled via the API and supports port failover in a more seamless way than our existing active-backup configuration does.
In 2.5.3, LACP is enabled by default for new clusters. If your switch ports are not configured for LACP, the interface will automatically downgrade to active-backup mode.
The active-backup mode that’s automatically enabled has one consideration. If a failover happens, the backup port will take over as expected. When the active port comes back up, the active port will not resume as expected. Traffic will instead be pinned to the backup port until another failure event happens.
To avoid this behavior, you can explicitly set the ports to active-backup with the following command:
qq network_conf_mod --bonding-mode ACTIVE_BACKUP
For clusters created before 2.5.3, you can explicitly enable LACP using this command:
qq network_conf_mod --bonding-mode IEEE_8023AD
NOTE: Be aware that making these changes will trigger a quorum formation event while the new network bond is negotiated per node and will result in a small outage.
You should now be able to successfully configure LACP in Qumulo Core
