Topology error when calculating LACP speed

GiuseppeR

Hello everyone,

inside an ORG I used 3x gigabit RJ45 to link 2x switches, but the LACP settings on both sides are related to 4x ports.

The issue is the fact that the Topology shows me the link at 4 Gbps also when I use only 3x cables:

How can I fix that?

Hi @GiuseppeR,

To help us reproduce the issue locally, could you please clarify the following:

• The models of the two switches
• Their firmware versions

Additionally, please enable Zyxel Support Access and share the org/site name with us.

Thank you for your cooperation!

Hi @GiuseppeR,

After confirming, the LACP speed shown in NCC topology is based on configured port count × individual port speed (e.g., 4×1G = 4Gbps), regardless of actual link-up status. This is the current spec design.

We understand this behavior can be confusing, so our team is actively discussing enhancements for better user experience.

We've also created an ideas post. We encourage you and other users who are interested to show your support by commenting on or voting for it.

Thank you for your patience and understanding!

Hi @Zyxel_Tina

thanks for the update.

It should be great also considering that other links inside the Topology have the ability to show degraded performances.
