Cisco ASA multicontext firewall-Interface bandwidth utilisation

[sreeraj.murali]

Hi,

We are using Cisco ASA Multicontext firewall,with multiple customer firewall instances. All the firewall instances is using the shared Outside interface. Now the issue, the one of the customer network is peaking the Internet utilisation. Please guide, how i can find out, which customer context is peaking the Outside Interface Circuit.

Please advice.

Thanks

best is to use netfow to find the source IP utilisation on the internet termination.

Yes, That can be done. I will have to install the netflow instance for each and every customer.

Could you please advice, the command available in Cisco ASA multicontext firewall instance to check the Interface bandwidth utilisation.

You do not required to install each instanace for every customer, you have 1 Internet (i belive to exiti to internet) pipe for all the device, so your Flow will be one config.

you get top IP address utlising the bandwidth.

ASA point each context means, each act as different FW. ( if you are using ASDM, click on system, you can view context usage some stastics.
