2911/K9 throughput when using dmvpn

[taimoor4engg]

Hi All, 

I have a 2911/k9 router with Guest network and DMVPN configured, as per documents the speed of the router is 180Mbps but I am getting 100Mbps for Guest and 20Meg for Tunnel users. is this fine ? should I get 100Mbps on both or 100 + 20 will work ?

Do you have the HSEC license applied to the router? Without it traffic is limited, so you'd not get 180Mbps. You'd probably noticed an error in the logs when you exceed the permitted bandwidth.

Looks like its not enable as the IOS is ipbasek9:

Router 2911, I was under the impression all 2911/K9 have this option enable. I dont see any error on logs but I do see high utilization on process Licensing Auto U.

From experience without the HSEC license the router is limited to 85Mbps, this is/was standard. You'll need it in order to get the full bandwidth.

When you exceed the limit you should see this error:

” %CERM-4-RX_BW_LIMIT: Maximum Rx Bandwidth limit of 85000 Kbps reached for Crypto functionality with securityk9 technology package license.”.

You could possibly get an eval HSEC license and see if the performance improves
