VCStack + Link Aggregation
Prior to the advent of the Vir tual Chassis Stacking (VCStack) solution, high availability in enterprise networks was achieved by
provisioning redundant links (with STP) and redundant routers (with VRRP). In normal operation, bandwidth and routing power would
sit idle in the network.
Allied Telesis now provides a truly resilient network. In normal operation, all bandwidth and all 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 will be lost, but the network will still
be fully operational and all remaining resources will continue to be fully utilized.

The key advantage comes from configuring the links from the edge to the core using 802.3ad link aggregation. This is possible
because VCS suppor ts link aggregation on por ts across different vir tual chassis members, providing:
■
Full network bandwidth, as both por ts are active; no links are blocked, as some would be with spanning tree.
■
Minimal network disruption if a link fails. The process within a switch when an aggregated link fails is ver y simple and the vir tual
chassis almost instantly adapts its data forwarding on the loss of the link.
"Loading the manual" means you need to wait until the file loads and becomes available for online reading. Some manuals are very large, and the time they take to appear depends on your internet speed.
