Support of vPC on the Cisco Nexus 5000 access switch enables various new design options for
the data center Access layer, including which of the following?
A.
The vPC peer link is not required for Access layer control traffic, and can instead be used to
span VLANs across the vPC access switches
B.
A single switch can associate per-interface with more than one vPC domain
C.
vPC can be used on both sides of the MEC, allowing a unique 16-link EtherChannel to be built
between the access and aggregation switches
D.
Allows an EtherChannel between a server and a access switch while still maintaining the level
of availability that is associated with dual-homing a server to two different access switches
C
Double-sided vPC: If the access switch platform also supports vPC, as does the
Cisco Nexus 5000 series, vPC can be configured on both the aggregation and access
layers. This configuration allows a maximum of 16 links to be bundled into a single
vPC between the aggregation and access switches. In this type of design, vPC can
also be used toward dual-homed servers on the access layer. Eventually, this results in
having all links from the server all the way up to the aggregation layer actively forwarding
traffic.
