Using Transparent Bridge Services
117351-A Rev. A 1-21
Parameter: Enable
Default: Enable
Options: Enable
| Disable
Function: Enables or disables bridging on the entire router.
Instructions: Set to Disable if you want to disable bridging for all circuits on the router.
MIB Object ID: 1.3.6.1.4.1.18.3.5.1.1.1.1.2
Parameter: Bridge Table Size
Default: 1024 entries
Options: 1024
| 2048 | 4096 | 8192 | 16384 | 32768 | 65536 | 131072
Function: Specifies the maximum number of MAC address entries allowed in the
forwarding table.
If you increase the number of table entries, the bridge is more efficient but
uses more memory.
If you save a change to this parameter in dynamic mode, the bridge
disables and then reenables itself, thereby deleting all previously learned
addresses.
Instructions: Click on the Values button to select a value for the table size, after
accounting for the number of protocols running on your router and the
size of the bridged network. If you type a value other than one of those
listed by the Values button, the system returns an error message.
The translation bridge, if configured, also adds addresses to this
forwarding table. Therefore, if you configure the translation bridge,
remember to account for the number of addresses it learns from the
source route network.
Select the 131072 option only if the router is running IP Host Only and no
other protocols are running on the router. If you select 131072, the system
automatically disables the next parameter, Enable Forwarding DB.
