Except for enabling Spanning Tree, most users do not need to change the

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
enable 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 enabled.
To change the Spanning Tree Priority, use the command:


set bridge spanning_tree_priority <priority value>
Because routers base their forwarding decision on network-level addresses,
packets that are routed over a WAN are transmitted without MAC-layer
addresses. Additionally, address resolution procedures that can be used to
determine the destination MAC address for a packet are not required.
Conversely, packets that are bridged over a Wide Area Connection include
MAC-layer information. Address resolution procedures are required.
MAC-Encapsulated Routing uses network-level addresses for forwarding decisions
but transmits MAC-layer addresses over the Wide Area Connection. Additionally,
address resolution procedures are used. To the remote site, the packets appear as
if they had been bridged.
This feature allows the routing features of the OfficeConnect Remote 812 (i.e.,
address translation, DHCP Server, DNS Proxy, etc.) to be employed in a bridged
environment.
MAC-Encapsulated Routing is specified on a per-VC basis. When
MAC-Encapsulated Routing is enabled in a VC profile, packets for the routed
protocols configured by the profile (i.e., IP and/or IPX) will be sent using the
appropriate bridged encapsulation. If the configured network service is RFC 1483,
