Hi there,
I'm having an issue with my Cisco 6509. One of Internet configured as trunk Interface direct with a HP7500 is showing reliability 255/255, txload 238/255, rxload 8/255.
The Issue is that my Cacti Server show me that only 10% of the link is in use but if you look at txload you can see that almost 100% of the bandwidth is in use..
What can I do in order to figure out what's going on with this Interface. I'm thing about to put wireshark and configure a port monitor in order to capture the packets.
Is anyone has any tip to do a troubleshoot with this issue??

You may want to initially want to use netflow so you'll be able to know what's causing the high load on this etherchannel.

Thank Leo
I´m gonna try to use netflow,

This pretty much tells you your port channel is pretty full. How many ports in the channel?

How many ports in the channel?
Output shows Gi 8/19 and Gi 8/20 the only members in the port channels that are active.
