How to Collect Bandwith between two Cisco Catalysis Devices

I am a novice when it comes to Cisco Networking so I am sorry for any stupid questions.

I am looking to collect and monitor bandwidth utilization between my Core Cataysis  and my Access Cataysis.

I am not sure what steps need to be taken to try and accoumplish this?
Any guidence would be appricated

There are multiple ways you can achieve this.
- 1. Use applications like PTRG, OPManager, Solarwind IP SLA Monitor etc
- 2. Configure monitor on the devices in conjunction with or without IP SLA

You can enable SNMP on those switches and use Solarwinds Realtime Bandwidth Monitor (free tool) to monitor the interface (or the portchannel if there are muliple connections between the two switches).

The realtime bandwidth monitor will connect to one of your switches and you can choose which interface you want to monitor.

Let me know if you have any questions.

Like I stated I am a novice when it comes to Unix/Cisco command lines.
Can one of youe supply ways to show me whether the SNMP is enabled, Netflow, and the version of Netflow

I Downloaded PTRG, but I am only able to establish a PING sensor

The easiest tool you may want to try is the Solarwind IP SLA (free tool).


SNMP is usually enabled by default.

show run | include snmp

you should get something similar to:
snmp-server community public RO
snmp-server community private RW

These are the same commands to turn RO or RW on. public or private could be any word

There's a lot about SNMP and I would advice that you should do a little tutorial on this as you proceed. For instance, It is not good practice to use default community strings on your devices, especially for read-write (RW) community string.

What does that mean for me?

Use "monitor" for read only SNMP string when you configure SNMP on PRTG or real time bandwidth monitor.

Can I leverage Netflow to collection data using PRTG or just SNMP.
