800 Series Router WAN Throughput

[davidstrg99]

Can anyone tell me which 800 series routers allow 20 Mbps throughput across the WAN port?

I have a cable modem that outputs this speed but am having difficulty finding a router that will accept this throughput across the WAN port.

Thanks.

Cisco routers have hardware encryption. Consequently, there is not much performance difference.

Hi,

I'm also having the same confusion. Our 881 shows on paper to push  roughly 12Mbps, but when using simple routing and acl we are obtaining speeds of 70Mpbs.

Therefore I don't see the pdf, is correct in any way, and if this is half duple then surely the speed is doubled on full not halfed. Unless I'm missing something.

I would appreciate if someone could please explain.

You have an 881, not an old "800 series"..

Above has been linked the white paper to reference for ISR G2 routers, that is consistant with your performance observation.

Table 1. Cisco ISR G2 RFC 2544-Based Performance (kpps and Mbps)

kpps

(64-byte packets)

25 50 100 290 330 330 352 479 579 833 1845 982 2924

Mbps

(1500-byte packets)

197 198 1400 2770 2932 3114 3371 3502 5136 6903 6703 8025 8675

Hi Paolo,

Thank you,

Therefore a Cisco 881 should be able to router over 100Mbps of traffic?

I also have some old routers which I would like to use in our lab, how do I find out which routers these are? I know the model numbers but the 'G2' section?

[paolo bevilacqua]

Yes, about that.

For lab purposes, performances are not important.

Thank you for the nice rating and good luck!

[John Peterson]

I understand but these router in our labs we use on production environment post testing features.

How were you able to identify G2 routers?

Your welcome on the rating.
