Hi Folks,
Just 2 cents on this behavior…
When configuring LAGs, consider the following guidelines:
- The LAG must be configured on both sides of the link.
- The interfaces on either side of the link must be set to the same speed.
- You can configure and apply firewall filters on a LAG.
- LACP can optionally be configured for link negotiation.
