Field Description
Total of 300 station blocks 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.
Bridge Group The number of the bridge group to which this interface is assigned.
