Recommendations

Info

oth devices are online, and also to avoid active/active or split-brain scenarios that could introduce loops into the vPC topology. The vPC peer-keepalive link can be either 1 Gbps or 10 Gbps. • vPC peer link: Used to exchange state information between the vPC peers and also provides additional mechanisms that can detect and prevent split-brain scenarios. Some other terminology that you must understand for vPCs follows: • vPC link: A link configured as a vPC on the Nexus. The downstream device sees the vPC link as a normal port-channel. • vPC Role: Each of the members of a vPC domain participates in an election to determine the primary and secondary devices in the vPC domain. Only the vPC operational primary devices generate and receive BPDUs. This election can be manipulated by way of a role priority, which is defined under the vPC domain configuration mode. • Orphan Port: An orphaned port is a link that is not configured as a vPC link that is carrying a VLAN present on a vPC link, or the vPC peer-link. Orphan ports should generally be avoided if possible. Orphan ports can be displayed by using the show vpc orphan-ports command. Orphan ports can be avoided by keeping the vPC domain “pure,” which is to say that all devices are dual homed to both members of the vPC domain with vPC links. Note On the Nexus 7000, the mgmt0 interface can be used as the vPC peer-keepalive link but should be avoided if at all possible. On the Nexus 7000, the mgmt0 is actually a logical interface representing the physical management port of the active supervisor. During processes such as supervisor switchover during hardware failure or In- Service Software Upgrades (ISSU), the physical link supporting the mgmt0 interface might change, causing a disruption of the keepalive messages. By using normal switch interfaces, additional levels of redundancy in the port-channels can be used. If the mgmt0 interface is used as the peer-keepalive link, it is critical to ensure that all physical management ports are connected to an external device, such as a management switch. The remainder of this section demonstrates configuration based on the topology shown in Figure 2-7.
