Chapter 25 Configuring BXM Virtual Trunks
Example: Virtual Trunk Across an ATM Network
• A virtual trunk is added between port 3 on the BXM and port 2 on the UXM (see Figure 25-6).
Given this situation, you would perform these steps:
The VPI values you choose by using cnftrk must match those used by the cloud VPC.
In addition, both ends of the virtual trunk must match with respect to:
• Transmit Rate
• VPC type
1. Initial Setup Contact Customer Service to enable virtual trunking
on the nodes in your network.
2. In the public
ATM cl oud
Obtain the VPCs for the virtual trunks for the service
provider. These are the VPCs that are configured
within the ATM cloud by the service provider to
support the virtual trunks.
