Layer 2-4 Intelligence
The 8500 series packs a lot of features in one
rack unit.With advanced AlliedWare®
technology, the 8500 series switches allow
network administrators to configure the switch
to examine packet formats and content from
Layer 2, Layer 3, or Layer 4 (also known as the
MAC, IP and TCP/UDP layers). After these layer
parameters are defined and detected, the
switch can trigger network decisions such as
Access Control Lists (ACLs) for protection
against DoS attacks, establishing rate limits for
excessive bandwidth usage, and altering QoS to
support converged applications
