Bandwidth Utilization

[anthony.dyne]

Hi

Our VPN Server terminates IPSEC Tunnels, GRE Tunnels and EZVPN Server, how to identify which tunnel utilizes how much bandwidth.

Appreciate input on this request.

cheers

You can use SNMP to monitor the bandwidth.

For GRE, you can just monitor the tunnel interface for bandwidth usage.

For IPSec VPN, you can use "IPSEC-FLOW-MONITOR-MIB" if it is a IOS device.
