Can someone run a hardware throughput command on a stock ISR4461?

[pcweber]

I need to replace a pair of ASR1001-X routers that are coming to EOL in 2025. They each peer with ISP's on 10GB ethernet circuits. I then also have the inside interfaces facing out firewalls running 10gb.. So, I need 20 GB total throughput across the router hardware as I understand it. I have found conflicting information on the ASR4461 capacity. Some cisco documents say 7GB, some say 19gb IPV4 forwarding. I am curious what a standard 4661 without Boost or Performance licensing shows with the following command. As a note I am not looking for encrypted traffic throughput( which I know is always lower), just non encrypted ISP traffic throughput.

L3-1001X#show platform hardware throughput level

My current ASR router responds with this output of which I take as 20gb: The current throughput level is 20000000 kb/s

I dont understand why they would deliver a router with four 10gb interfaces and have a max platform throughput of 1.5gb stock, and 3gb with the Boost license?

No Performance License

With Performance License

4461

1.5  Gbps

8 x PPE + 1 x I/O

3 Gbps

I dont think the throughput is for all traffic pass through router.

These type of router use hybrid i.e. SW &HW to forward traffic.

The throughput here is for traffic forward by SW only.

The 3 Gbps is when using the performance license, possibly more than twice that is possible with the boost license, but unlike the former which is, somewhat, guanteed, the latter is not and can be very variable depending on router's config and traffic mix.

As to why a Cisco router has interfaces that have bandwidth in excess of its actual forwarding capacity, Cisco has been doing that for decades.  As to why Cisco does that, only they can say, but it's unusual to have a device need to provide sustained wire-rate to all its ports concurrently.

Replacing an ASR 1k, where you want to support 20 Gbps, you may want to look at the low end Catalyst 8k routers.
