300Mpbs WAN speed. What hardware do I need?

[xavierloza1]

Hello all,

We've just acquired a 300Mpbs/20Mpbs cable line. Shortly after I realized my 2821 router is unable to handle this much bandwidth and it caps out at 150Mpbs download. Let me know which router/switch combination is able to handle 300Mpbs. Also, I'm running Cisco3750G switches as well. Would these switches be enough? Thank you.

Hi,

Have a look at Cisco 4000 series routers, Cisco 3750G should be fine.

Table 4.       Specifications of Cisco 4000 Family Integrated Services Routers

Technical Specifications

Cisco 4451	Cisco 4431	Cisco 4351	Cisco 4331	Cisco 4321
Aggregate Throughput	1 Gbps to 2 Gbps	500 Mbps to 1 Gbps	200 Mbps to 400 Mbps	100 Mbps to 300 Mbps	50 Mbps to 100 Mbps

For 320 Mbps of aggregate bandwidth, Cisco recommends a 3945 for 150 Mbps (WAN, i.e. 300 Mbps).  (See attachment.)

Your 3750G has multi-gig capacity, so your 300 Mbps shouldn't be an issue for it, unless it's already highly loaded.
