How to find VPN tunnel BW

Unanswered Question

Hi,

My router is 2851 and running :c2800nm-adventerprisek9-mz.124-24.T2.bin


And I have 13 differenet IPSec vpn tunnels to other locations


How can I find the each VPN tunnel bandwidth


I explore teh NBAR method, aand its dont recognise IPSEC traffic


And,

sh crypto engine accelerator statistic

command give yo last 5 minutes bits/sec in and out capacitry but it is the total.


I thought I can go to other end, which is 1760 routers and they dont give you 5 mts tarffic in and out info like 2851

Hello Asoka,


I would use


ip accounting output-packets


on physical interface of HQ router


you should be able with

sh ip accounting


to see the flows of IPSec you know the endpoints IP addresses


or an ACL with log option with one line with log option for each IPSec tunnel



Hope to help

Giuseppe
