•
In the IP Tunnels screen, configure the Mode parameter in designated bridge
candidates to Listen.
•
In the Tunnel Filters screen, configure the filters in root candidates and in other
access points that can be attached through an IP tunnel. IP tunnel filters are
consistent with Ethernet filters.
•
For networks using IP networking on end devices, Intermec recommends that you
enable the ARP server capability in the access points.
•
Determine if you need to enable bridging on remote subnets. For example, bridging
must be enabled if an Intermec NNL gateway is attached to the remote subnet. For
help, see "Configuring the Spanning Tree Parameters" earlier in this chapter. The
designated bridge candidates must have permanent IP addresses and must be able to
receive IP hello messages from the root access point. An access point will receive
IP hello messages if the messages are sent to the unicast IP address of the access
point, or to an IP-directed broadcast or IP multicast address. Note you may need to
enable IGMP for IP multicast.
To configure the IP Tunnels screen
1. From the main menu, click IP Tunnels. The IP Tunnels screen appears.
2. Click the down arrow on the right side of the Port Control field and choose Enabled.
Choose Disabled if you do not want this access point to participate in IP tunnels.
