ISR4321/K9 Throughput and Bandwidth supported

[Ivan Eduardo Herrera Salas]

Hello

I have a question related with the maximun Bandwitdth that i can offer to a client with one cisco ISR4321, using the front panel 2 ports.

the question is if this router can support simetric 100Mbps conecting the WAN on the port GigabitEthernet0/0/0  an the LAN on the port GigabitEthernet0/0/1.

i attached the show inventory and the show interface summary.

i canot determinate if the OQD are related with throughput issues.

This router has a base performance of 50Mb/s, and you can purchase a licence to upgrade it to 100Mb/s.  Has the extra performance licence been purchased and installed?

It should look something like this:

The router has a Evaluation licence to increase the throughput to 100Mbps, but my question is if the throughput is enought to support the simetric bandwidth, i understand that throughput means all trafic that the router can forward without droping any traffic. so if i want a internet link with 100Mbps of bandwidth i would need a throughput of 200Mbps to manage incoming and outgoing trafic at full capacity, is it right?

And what if i use the 2 front integrated ports to conect LAN and WAN,will the througput limitation afects the trafic between the 2 routed interfaces when i operate at 50Mbps dowloading and 60Mbps uploading?.

[Philip D'Ath]

It is 100Mb/s of aggregate bandwidth.  So 50Mb/s in and 50Mb/s out, or 25 Mb/s in and 75Mb/s out, etc.  Any combination where the total adds up to 100Mb/s.

I think you get a message in the log when you hit the system performance limit shaper.

[Joseph W. Doherty]

My understanding is the same as Philip's, i.e. you would need a larger 4K ISR, such as an performance upgraded 4331 or a base performance 4351, to fully support 100 Mbps, full duplex.

If you don't need WAN features, you might also consider using a L3 switch.
