5 Repeat steps 2-4, as desired, to add more addresses to the Bridge Static Table.
To view the current Bridge Static Table, select [1] List Static Table from the
n
Bridge Static Table menu. The List Forwarding Table includes the following
columns of information:
MAC Address—The destination MAC address.
Transmit VPI:VCI—The transmit virtual path indicator (VPI) and virtual channel
indicator (VCI) numbers for the destination MAC address.
Receive VPI:VCI—The receive virtual path indicator (VPI) and virtual channel
indicator (VCI) numbers for the destination MAC address.
Transmit Slot:Port—The port (slot and port number) on which the destination
MAC address is located.
To delete an address from the table, select [3] Delete MAC Address from Bridge
n
Static Table menu and enter the number corresponding to the address you
want to delete. Then enter [Y] at the confirmation prompt to delete the
selected address from the Bridge Static Table.

Enabling and Disabling the Spanning Tree

Spanning Tree (IEEE 802.1d) is a technique that detects loops in a network and
logically blocks the redundant paths, ensuring that only one route exists between
any two LANs. It eliminates the duplication of packets and provides fault tolerance
for resilient networks.
To enable or disable the Spanning Tree, follow these steps:
1 From the Configuration Management menu, select [3] Manage Bridge to display
the Manage Bridge menu, shown earlier in Figure 108.
2 From the Manage Bridge menu, select the number corresponding to the slot and
port combination for which you want to enable or disable the Spanning Tree. The
Bridge Menu for the selected slot/port combination appears, as shown earlier in
Figure 110.
3 Select [1] Setup to display the Bridge Setup menu, shown earlier in Figure 112.
4 Select [1] Set Spanning Tree Operation. The following prompt appears:
Enter Spanning Tree Operation Status (1=Disabled, 2=Enabled):
5 Enter [1] or [2] to disable or enable the Spanning Tree.
For further information on Spanning Tree and how it operates, see "Spanning
Tree" in Chapter 4.
In addition to the standard bridging configuration described in the previous
section, you can also configure IP over ATM for either of the PathBuilder S600's
Ethernet ports. IP over ATM is a method to pass IP traffic across an ATM network;
it follows RFC 1577.
To configure IP over ATM for an Ethernet port, follow these steps:
1 Access the IP over ATM menu for the Ethernet port for which you want to
configure IP over ATM.
a From the main menu, select [2] Configuration Management.
