Chapter 7 Configuring vPCs Information About vPCs Send document comments to [email protected] • Features That You Must Manually Configure on the Primary and Secondary Devices, page 7-10 • Configuring Layer 3 Backup Routes on a vPC Peer Link, page 7-11 Note You must configure the peer-keepalive link before you configure the vPC peer link or the peer link will not come up. (See the "Peer-Keepalive Link and Messages" section on page 7-11 for information on the vPC peer-keepalive link and messages.) You can configure a vPC peer link to configure two devices as vPCs peers. You must use the module in order to configure a vPC peer link. Note We recommend that you use the dedicated port mode when you configure a vPC peer link. For information about the dedicated port mode, see Chapter 2, "Configuring Basic Interface Parameters." vPC Peer Link and I/O Modules Support Only identical I/O modules on either side of a vPC peer link are supported. Using different I/O modules on either side of a vPC peer link is not supported. Mixing I/O modules on the same side of a port channel is also not supported. Table 7-1 displays the I/O modules that are supported on both sides of a vPC peer link. Figure 7-4 to Figure 7-7 show the configurations that are supported and not supported on both sides of a vPC peer link.
