OWL/IP Restrictions, Addressing Limitations | Intermec 6710 guide

APPENDIX E " OWL/IP

OWL/IP is activated by enabling the OWL/IP port in the access point. The port is an entryway to an IP tunnel originated by the super root on the home subnet, and terminated by a designated bridge operating on a remote subnet. Frames are encapsulated using the GRE protocol running over IP.

The super root can originate IP tunnels to eight or fewer IP addresses. The number of tunnels supported may be more than or fewer than eight, depending on the type of addressing used and redundancy needs within the installation.

The OWL/IP port differs from the physical NIC1, NIC2 and Ethernet ports within the access point. It is a logical port that provides IP encapsulation services for frames that must be routed to reach their destination. Once encapsulated, frames are transmitted or received through one of the three physical ports.

OWL/IP Restrictions

Addressing Limitations

Wireless stations using IP must be assigned IP addresses on the home subnet. Servers may be located on any subnet. However, it is preferable to choose the subnet that contains servers for wireless stations as the home subnet if possible.

Installation Limitations

OWL/IP tunnels should not be used:
