Hello, I'm working on updating your wireless network. You're replacing four Cisco APs with Aerohive and need to add VLANs for each new SSID. Your Brocade switch supports three VLANs: 100 (Internal/Secure), 110 (Primary LAN), 120 (Secondary/Guest). Each AP should have these VLANs assigned to the corresponding SSIDs. You're unsure whether to use SwitchPort Tagged or Dual-Mode for the VLAN assignments—do you want guidance on that choice? I can also help interpret your posted picture if needed. Thanks, Matthew.

Identify the required VLANs and assign them to the appropriate ports promptly

Dual-mode allows one VLAN to be untagged on a port while others carry tags. It functions similarly to Cisco’s native VLAN tagging feature. In recent ICS firmware updates, dual-mode is no longer supported and now uses tagged ports for untagged traffic, just like HP/Aruba implementations.

Hello, I attempted to assign int 1/1/2 with a VLAN tag of 120, but it’s already present in 110. Got any suggestions? Thanks, Matthew.

You're encountering an issue where you can only configure a single port as "tagged" for one VLAN, even though you previously managed multiple ports in Dual-Mode. It seems the feature has been removed or changed in your current setup. Double-check your configuration settings and ensure you're using the correct mode for your devices.

Ensure the specified VLAN is untagged before proceeding, regardless of your intent to convert it to a tagged configuration. I haven’t encountered any problems assigning multiple tags to a single port before.

Set up a trunk port to support several VLANs on a single port. The equipment connected there must mark traffic so it reaches the appropriate network segment.

for the fundamentals, trunk port supports several VLANs on one port. You should mark traffic coming from the device access port as untagged, letting each VLAN operate independently. If every VLAN has its own port, use an access port and keep all traffic untagged for simplicity.
