Enterasys Networks introduces the SecureStack C3 stackable switch that continues Enterasys' leadership in stackable switching. While delivering advanced switching and routing features, the SecureStack C3 delivers an industry-leading 384 Gigabit ports in a single stack. Expensive network downtime is reduced with reliability and availability features like Closed Loop Stacking, redundant core connections, redundant power options, and redundant stack management. The SecureStack C3 provides extensive security features and is an important part of extending Enterasys Secure Networks to the network edge, as well as providing a path to IPv6. The SecureStack offers unprecedented port density and performance for a stackable switch, while at the same time providing much more extensive Secure Networks functionality with the expansion of policy masks. The SecureStack C3's extensive Layer 2 and Layer 3 feature set includes optional support for IPv6. The SecureStack C3 supports Enterasys Secure Networks, the role-based architecture where every user is assigned an easy-to-deploy, yet highly granular role on the network. The SecureStack C3 supports up to 768 policy rules per switch or stack, so that all users - from sales to finance, from the president of the company to a guest user or contractor - are provided the capabilities and rights afforded to their productive role in the enterprise. The SecureStack C3 enables customers to deploy a low-cost network solution today that will continue to deliver benefits well into the future. A single C3 stack provides over 384 user ports that can be used in a fully converged network with IPv6, PoE, and advanced routing capabilities that rival those found in high-end edge chassis-based systems.
