Issue

A performance impact or outage is experienced when accessing the storage system through the LAN after implementing Cisco's vPC on Nexus 7000 or 5500 series switches, when ip.fastpath is enabled.

The storage system will respond to the MAC address of an individual switch/router and not the virtual MAC address of the two vPC devices.
