One thing you also mentioned - worth looking into a bit more thorough is the following: > Switch cisco 9200 / port uplink 2 / native vlan 1 / tagged all vlans. The 9200 series supports a maximum of 512 VLANs per stand-alone switch or switch stack. By default, VLAN IDs 1-512 are configured, but you can modify the active VLANs via the local status page or dashboard. If you attempt to allow more than 512 VLANs, the switch will not support it, and you may encounter configuration errors.
