VLAN registration occurs automatically. No user intervention is required.
Note
VLAN registration is summarized below:
1
Whenever an Ethernet port on a mesh access point is configured with a VLAN, the port requests its parent
to support that VLAN.
2
If the parent is able to support the request, it creates a bridge group for the VLAN and propagates the
request to its parent. This propagation continues until the RAP is reached.
3
When the request reaches the RAP, it checks whether it is able to support the VLAN request. If yes, the
RAP creates a bridge group and a subinterface on its uplink Ethernet interface to support the VLAN request.
4
If the mesh access point is not able to support the VLAN request by its child, at any point, the mesh access
point replies with a negative response. This response is propagated to downstream mesh access points
until the mesh access point that requested the VLAN is reached.
5
Upon receiving negative response from its parent, the requesting mesh access point defers the configuration
of the VLAN. However, the configuration is stored for future attempts. Given the dynamic nature of mesh,
another parent and its uplink mesh access points might be able to support it in the case of roaming or a
CAPWAP reconnect.
Enabling Ethernet VLAN Tagging (GUI)
You must enable Ethernet bridging before you can configure VLAN tagging.
To enable VLAN tagging on a RAP or MAP using the GUI, follow these steps:
Step 1
After enabling Ethernet bridging, choose
Wireless > All APs
.
Step 2
Click the AP name link of the mesh access point on which you want to enable VLAN tagging.
Step 3
On the details page, select the
Mesh
tab.
Step 4
Select the
Ethernet Bridging
check box to enable the feature and click
Apply
.
An Ethernet Bridging section appears at the bottom of the page listing each of the four Ethernet ports of the mesh access
point.
• If configuring a MAP
access
port, click, for example,
gigabitEthernet1
(port 1-PoE out).
Select
access
from the mode drop-down list.
Enter a VLAN ID. The VLAN ID can be any value between 1 and 4095.
Click
Apply
.
VLAN ID 1 is not reserved as the default
VLAN.
Note
A maximum of 16 VLANs are supported across all of a RAP’s subordinate
MAP.
Note
• If configuring a RAP or MAP
trunk
port, click
gigabitEthernet0
(port 0-PoE in).
Select
trunk
from the mode drop-down list.
