Main Office and Service Provider VPN 3000 Concentrators

In an enterprise environment in which thousands of remote users need VPN connectivity to the main office, it is necessary to implement a more robust model of VPN Concentrator. The Cisco 3060 and 3080 VPN Concentrators have the scalability to support 100Mbps of throughput. Both models are two rack units high (same chassis as 3015 and 3030) and come standard with 256MB of SRAM. A key difference between the 3060 and 3080 is that the 3060 comes standard with two SEP modules, whereas the 3080 has four. Because the 3080 has double the amount of SEP processing power, it can terminate up to 10,000 simultaneous sessions, as compared to the 3060, which can maintain up to 5,000 sessions. Both models can support up to 1,000 site-to-site sessions for intranet and extranet VPNs. A final difference is that the 3060 has an optional redundant power supply slot, but the 3080 includes a standard redundant power supply. Table 3.2 summarizes all the models of the Cisco 3000 VPN Concentrator family.
