Fetch Real time bandwidth of subscribers

[Kijush Maharjan]

Does anyone have any idea about the SNMP OID to fetch the subscribers real time bandwidth from Cacti? I have been using BNG in ASR9k.

hi Kijush,

what exactly do you mean by real-time bandwidth?

SNMP was never designed to provide real-time data. See http://www.cisco.com/en/US/docs/routers/asr9000/mib/guide/asr9kmib3.html for the list of supported MIBs.

If you have QoS on subscriber sessions you can check the QoS stats. You can export the stats via radius accounting (scales better in BNG solution than SNMP).

Hi Aleksandar,

Thank you for your valuable suggestion.

The value that i export from radius accounting won't be in kbps or mbps. I want to poll the bps values from subscribers virtual interface via snmp oid. I have been doing this in other vendors that has been pushed to our internal portal. 

It has made life easier for our support engineers to troubleshoot subscribers connection.

hope for your suggestion.

Regards,

Kijush

hi Kijush,

on the BNG scale that we support on asr9k, retrieving this kind of information via SNMP would be very challenging due to SNMP architecture. However, you can automate the polling of the interface statistics via XML. This document https://supportforums.cisco.com/document/61436/introduction-xml-asr9000 explains how to make use of XML for this purpose. To see on the router how the output would look like, run

show operational Interfaces InterfaceTable Interface/InterfaceName=<interface> xml

hth,
