4.3 Example of adding a Catalyst 5500 to an IBM 8265 ATM backbone
In our test configuration, we have an IBM 8265-based backbone with an IBM
8270 token-ring edge switch. We want to add a Catalyst 5500, with an ATM
LANE module, configured with an emulated Ethernet LAN and using MPOA to
create a shortcut route between a token-ring VLAN and an Ethernet VLAN.
Figure 47. Shortcut between token-ring MPC and Ethernet MPC
The logical configuration is shown in Figure 47 and the physical configuration
in Figure 48 on page 77. The MSS blade in the IBM 8265 acts as an MPOA
server. The MSS client UFC of the IBM 8270 is one of the MPOA clients. The
