The bridge operates in the store-and-forward mode, which filters out bad
packets and maintains optimum performance in both domains. Packet forwarding delay
is only 5
µs (plus packet time), much less than traditional store-and-forward bridge
products, enabling the 8000Xs to maintain high network performance. The bridge has
8K node address capacity, suitable for use in large networks. Addresses are self-
learning so that filtering / forwarding of 10 Mbps and of 100Mbps packets is
maintained correctly even when users move their connection, or change speed, or power
down.
Figure 2.8 : Internal view of 8000X with bridge module installed
The Magnum 8000X’s bridge module is implemented as a daughter board. 8000X units
have an LED on the front labeled BR that will be ON when the module is installed
internally. (The Model 8000X-A is an “add-on” unit for stacking, and has no bridge
inside, so it’s BR LED will be off). In a stack of Magnum 8000X’s and / or other
compatible hubs, only one unit with a bridge inside may be operating in any one stack.
