During normal operation with VCStack, all bandwidth and routing power in the network are fully available for use all the time. If a link or device fails, some of the bandwidth or forwarding power is lost, but the network remains fully operational and all remaining resources continue to be fully utilized.

The key advantage of VCStack comes from configuring the links from the access switches to the core as an 802.3ad link aggregation. With link aggregation across ports on different
