Monitor IPSEC Tunnel Bandwidth Utilisation on Cisco IOS

[manugarg19]

Hello All,

I want to monitor the bandwidth utilisation on IPSEC tunnel configured on Cisco router. Is there anyway I can do it.

Appreciate any ideas.

Thanks

If your IPSec tunnel terminates on a tunnel (VTI) interface, yes. If it terminates on a crypto map, the only way I can think of to do it is to use Netflow monitoring on the physical interface and capture ESP traffic between the peers.
