When the management interfaces of VELOS system controllers are configured in a LACP LAG, the VELOS system may incorrectly forward some ethernet frames ingressing one management interface out the other management interface. This behavior occurs during the period between when an interface links up and when the system completes LACP negotiation and adds the interface to the LAG. This can result in management switches incorrectly learning non-VELOS MAC addresses as being present on the VELOS management LAG interface.
VELOS management interfaces incorrectly forward non-VELOS frames from one management interface out the other, causing upstream switches to learn non-VELOS MAC addresses as being present on the VELOS management LAG interface.
- VELOS system - Management interfaces configured in LACP LAG
Configure the upstream switch to be an LACP lag first, then configure the VELOS system MGMT interfaces to use an LACP lag.
