Editing Translation Bridge MAC Address Conversions
Token Ring networks use functional addresses for frames addressed to more than
one station; Ethernet networks use multicast addresses for these frames. The
Translation Bridge Address Mapping window allows you to map Token Ring
functional addresses to Ethernet multicast addresses.
When the translation bridge receives a multicast frame from an Ethernet network
destined for a Token Ring network, it translates the frame’s multicast address to
the mapped Token Ring functional address. The translation bridge converts the
addresses of functional frames going from Token Ring to Ethernet to the mapped
multicast address.
Adding an Address Mapping
To add an address mapping:
1. Select Protocols > Global Protocols > Translation Bridge > MAC Address
Conversions from the Configuration Manager window (r
efer to
Figure 4-4).
The Address Mapping List window appears (Figure
4-6).
Note: You do not need to map functional addresses that are bit-reversed
versions of the multicast addresses. The translation bridge handles these
conversions automatically.
