show bridge cable-modem Field Descriptions
Description
Total number of forwarding database elements in the system. The
memory to hold bridge entries is allocated in blocks of memory
sufficient to hold 300 individual entries. When the number of free
entries falls below 25, another block of memory sufficient to hold
another 300 entries is allocated. Thus, the total number of forwarding
elements in the system is expanded dynamically, as needed, limited by
the amount of free memory in the router.
The number of the bridge group to which this interface is assigned.
