[tamilvanan.saravanan]

Hello Friends,

I have multiple IPsec VPN tunnels created in CISCO 3845 rotuer. would like to monitor the bandwidth utilization of individual IPSec tunnel. Can someone give the OID value to monitor them in MRTG or PRTG ?.

Thanks,

Do you use VTI interfaces or plain old lan-2-lan configuration syntax? If first, seems it is easy task, just find your tunnel interface index (snmpwalk will help) and monitor it like any other interface. If second then move to VTI interfaces and do as above.
