What is sifDesigRoot?

This read-only OCTET STRING, though its source description is empty, holds the Bridge Identifier of the root bridge as known via this specific port's network segment. An administrator compares it to the chassis-wide stRootID to rule out a segment-specific spanning tree inconsistency. For example, the admin compares sifDesigRoot for a given port against the chassis-level stRootID to rule out a segment-specific spanning tree inconsistency.
