vPC

vPC (Virtual Port Channel) enables a pair of NX-OS switches to appear as a single logical switch to downstream devices, providing active-active redundancy and eliminating spanning tree blocked ports for increased bandwidth utilization. It supports comprehensive domain configuration including auto-recovery, delay restore timers, peer gateway for routing over vPC, peer switch for STP convergence optimization, fast convergence, graceful consistency checking, and Layer 3 peer router functionality. vPC keepalive management provides configurable destination/source IPs, intervals, timeouts, VRF assignment, and QoS marking (DSCP, ToS, precedence) for reliable peer health monitoring.
