Cisco 1760, IOS 12.2. How do I monitor Bandwidth Utilitization?
Posted on 2004-04-14
I have a Cisco 1760 running IOS 12.2 w/Firewall services connected to another PIX 506 Firewall for VPN.
The router has 3 cards: T-1, 100 MB Internal LAN, 10 MB LAN (used for DMZ).
I want to know how much of my T-1 line's 1.5 MB bandwidth is being used.
I'm looking for something like this:
Approx 20% of the T-1 is used for VPN.
60% is used for the DMZ
10% is used for the internal LAN internet access
10% is not used.
I expect I'll get some sort of raw counters and have to compute the %s. I don't really expect the router to provide the data in exactly this format.
How do I get the data I need?
I have a syslog server setup for monitoring the access rules, if that is useful I can send data to the syslog, if I can mark it with a different souce tag or otherwise sort it out of the other noise at the syslog server.
