Configuring IP Over ATM
4 Enter y or n.
If you enter y, a screen appears with a list of existing virtual circuits. Enter the
n
number corresponding to the virtual circuit to which you want to attach the
destination MAC address.
If you enter n, the MAC address will be associated with this Ethernet port.
n
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 Bridge Static Table includes the following
columns of information:
MAC Address—The destination MAC address.
Location—One of the following two types of entries:
ENET <slot/port>—Ethernet slot and port number. This type of entry is
displayed when the MAC address is reached through that port.
VC <non-Ethernet side of VC data>—The card type, slot and port
number, and other virtual circuit parameters, such as DLCI number, for the
non-Ethernet side of the virtual circuit. This type of entry is displayed when
the MAC address is reached through that virtual circuit.
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 116.
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 118.
3 Select [1] Setup to display the Bridge Setup menu, shown earlier in Figure 120.
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 S700's
Ethernet ports. IP over ATM is a method to pass IP traffic across an ATM network;
it follows RFC 1577.
