The view of a node in a port-labeled network is an infinite tree encoding all walks in the network originating from this node. We prove that for any integers $ngeq Dgeq 1$, there exists a port-labeled network with at most $n$ nodes and diameter at most $D$ which contains a pair of nodes whose (infinite) views are different, but whose views truncated to depth $Omega(Dlog (n/D))$ are identical.
