Hi Robinson, From my point of view. Port mirroring of VLANs requires additional processing and resources on the switch, as it involves copying traffic from multiple VLANs and forwarding it to a single monitoring port. This can be particularly resource-intensive in high-traffic environments and may impact the overall performance of the switch. That said, it's always worth submitting a feature request to Meraki to inform them about your specific requirements and the use case for VLAN-level port mirroring. Meraki has a dedicated portal where customers can submit feature requests, and they often use this feedback to inform their product roadmap and prioritize new features and enhancements. Please look at the following documentation, which hopefully can be helpful for you. https://documentation.meraki.com/General_Administration/Other_Topics/Give_your_feedback_(previously_Make_a_Wish) Thanks!
