Re: Cisco G2 ISR WAN performance of 1Gbps?

Hi Azhar,

The highest spec ISR G2 - 3945 - can handle 150Mbps of real throughput
with all services turned on. If you require true Gigabit throughput then
I suggest you look at the Cisco ASR 1000's, and not the small one,
equipped with an appropriate SIP/SPA module.
Remember that the ISR's are software routers.

regards Andy

> A: A: The HWIC bus interface is limited to 400 Mbps of full duplex. The actual throughput of the Gigabit Ethernet HWIC is limited by the throughput of individual platforms. Under bidirectional traffic of 1518 bytes or larger, the Gigabit Ethernet HWIC can support up to an aggregate of 350 Mbps on Cisco 2811 and 2821 routers, 400 Mbps on Cisco 2851 routers, and 500 Mbps on Cisco 3800 Series platforms.
