how to get logs for interface when my bandwidth cross 70% Cisco 3900 router

[Sijo Mathew]

is there any way that I can get a log for the interface when my bandwidth cross 70% in my Cisco 3900 router

Using an SNMP to poll the interface bandwidth statistics. And when a threshold is met you get alerted. Using something like solarwinds for monitoring would be effective.

Unless you have another requirement? Seeing top talkers IP/protocols you can look at netflow configuration.

Hi Sijo,
You can also you prime infrastructure to monitor interface parameters and set thresholds.
