Bridging
Setting Bridge Translation
When bridging between Ethernet and Token Ring networks, it is necessary to
alter the MAC (Media Access Control) layer information. The Bridge Translation
window controls the default frame translation that will occur for Token Ring
frames that are bridged to Ethernet.
If the device that is being monitored via SPECTRUM Element Manager is set to
operate in Auto Translation Mode, it has the ability to learn the frame type that is
used for a given Source Address from its Ethernet MAC address.
However, when the Token Ring bridge port receives a frame from an unlearned
Ethernet MAC address, it is necessary to conÞgure the default Token
Ring-to-Ethernet frame translation. When the bridge is operating in Auto
Translation Mode, the learned frame type for a given Ethernet MAC address will
override the default setting which may be conÞgured in this window.
