Switch Configuration and Setup

When implementing multiple VLAN's from the controller to your Cisco switch, the switch port that is connected to the Meru Controller must be configured to support trunking for the VLANs that are configured on the Controller. If no VLANs are used, trunking is not necessary.

The Cisco Catalyst Ethernet Switch configuration below assumes trunking to Meru Controller is desired for VLANs 10 and 20. It is recommended to prune off any VLAN's on the switchport that are not being utilized on the Meru controller.

Note the helper-ip address in the VLAN interface is configured, which is used to make sure the DHCP broadcast messages from the requesting client are forwarded to the unicast IP addresses of the DHCP server across VLANs

       interface GigabitEthernet1/1

    switchport mode trunk
    switchport trunk allowed vlan 10, 20
       !
    Interface Vlan10
    ip address 10.1.10.1 255.255.255.0
    ip helper-address 10.1.1.254

    Interface Vlan20
    ip address 10.1.20.1 255.255.255.0
    ip helper-address 10.1.1.254
   

For Ports that do not need trunking, “switchport mode access” would be used instead of trunk mode, and the access VLAN number would be configured. To confirm the configuration, use the Catalyst switch command “show vlan” for the list of the configured VLANs and associated ports. In order to verify the trunking configuration, use the command “show interface trunk” which will display the status for trunking on each switch port, the encapsulation type used, the native VLAN for the trunk port, and the VLANs that are allowed and active in the management domain.

For further assistance on configuring your Cisco product, contact your Cisco TAC representative.
