Gateway Features

The zNID is a full-featured gateway with integrated DHCP server, ALG's,

NAT Router, PPPoE Client, scheduling, comprehensive logging, and

more. The zNID product line implements a very flexible QoS allowing the

service provider to guarantee that services are being prioritized correctly

and the end-user is getting the Quality of Experience that is expected.

The indoor zNID is designed for high performance applications. It

features one Gigabit Ethernet port and three Fast Ethernet ports, in

The zNID has full VLAN support with QoS. The packets in the VLANs are

prioritized based on the IEEE 802.1p priority bits. In addition, each VLAN

The zNID supports prioritization at the higher layers through the use of

the Diffserv bits (RFC2474, RFC2475).

also managed by the Zhone Network Management System (ZMS), using

SNMP. Software upgrades and configuration backups can be handled

automatically by the ZMS using the CPE Manager feature.
