Introducing the Contivity Extranet Switch
1-3
To restrict access, the Switch uses packet filtering based on Protocol ID,
Direction, Source and Destination IP addresses, Source and Destination Ports,
and TCP connection establishment. Additionally, Nortel Networks provides
you with a set of predefined filters that you can use either directly or tailor to
your network needs.
The unique quality of service (QoS) mechanisms include call admission
and packet forwarding priorities, and support for Resource ReSerVation
Protocol (RSVP).
The HTML and Java Web management interface allows different Switch
administrators to have different access rights, including configuration, status, and
monitoring. The Switch offers RADIUS accounting support and extensive
logging, including events, system, configuration, and security logs.
