IP Forwarding refers to the routing of IP packets from one interface to another. It
does not affect communicating to the OCR 812 itself. Even when IP Forwarding is
disabled, you can perform non-routing functions such as use a Web browser to
manage the unit and use PING.
To see the current IP Forwarding status use the command:


show ip settings
To disable IP Forwarding use the command:


disable ip forwarding
The advanced bridging configuration options include Aging Time, Forward Delay,
Spanning Tree, and Spanning Tree Priority.
To see the current settings for these options, use the command:

Except for enabling Spanning Tree, most users do not need to change the
advanced parameters from their default settings
The Aging Time is the time (in seconds) for aging out forwarding table
information.
To change the Aging Time, use the command:


set bridge aging_time <seconds>
The Forward Delay is the time (in seconds) to wait while learning forwarding
information before starting to bridge packets.
To change the Forwarding Delay, use the command:


set bridge forward_delay <seconds>
Spanning Tree refers to the Spanning Tree Protocol which is used to eliminate
network loops between bridges.
To disable or enable Spanning Tree, use the commands:


disable bridge spanning_tree

The Spanning Tree Priority is the priority assigned to a bridge that is running the
Spanning Tree Protocol. It is used for prioritizing the bridges when Spanning Tree is
