Configuring Transparent Bridging and Spanning Tree Using the BCC

117351-B Rev. 00

6-11

To reenable transparent bridging on the router, navigate to the global bridge

prompt and enter:

state enabled

For example, the following command reenables transparent bridging on the router:

bridge#

state enabled

Managing the Forwarding Table

The transparent bridge’s forwarding table stores information about the source

addresses for frames that the bridge transmits. The following sections describe

parameters that you can set to manage the amount of memory that the forwarding

table uses, allow access to the forwarding table from the MIB, and clear the

forwarding table of all entries.

You can also specify that the contents of the forwarding table be sent to the

router’s log. See “

Sending a Copy of the Forwarding Table to the Log” on page

6-14 for instructions.

Managing the Amount of Memory that the Forwarding Table Uses

You can specify the maximum number of MAC address entries allowed in the

transparent bridge’s forwarding table. If you increase the number of table entries,

the bridge is more efficient but uses more memory. By default, the forwarding

table size is 1024 entries.

To change the forwarding table size, navigate to the global bridge prompt and

enter:

forward-table-size

<size>

size

is the maximum number of MAC address entries allowed in the forwarding

table and must be one of the following values:

1024

2048

4096

Note:

If you change the size of the forwarding table, the bridge disables itself

and then reenables itself, thereby deleting all previously learned addresses.
