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 1-1 displays the I/O modules that are supported on both sides of a vPC peer link. Figure 1-4 to Figure 1-7 show the configurations that are supported and not supported on both sides of a vPC peer link.
