Bandwidth Management
With the Bandwidth Management feature, you can allocate the outgoing
capacity of an interface to specific types of traffic. You can also ensure
that the Contivity 221 forwards certain types of traffic (especially real-time
applications) with minimum delay. This feature allows you to manage
bandwidth for the Contivity 221 by configuring classes and filters for LANs
and WANs.
