Hello Guys,
@Richard Burts @Joseph W. Doherty @Reza Sharifi @Deepak Kumar @paul driver @Georg Pauwen
I am using cisco 4506 series,
Is there any way in real-time that i can see that trunk port is going through congestion and dropping is happening.
I have the source IP or mac of device and destination Ip or mac .
Thanks

Hi ITExpert
when you say drops in real-time that still means drops per seconds or minutes. So repitative show interface should do that enough although not practical. You other obvious option is to rely on SNMP and the you will have historical data as frequent as you pull the interface for data. I do not know of anyway to find drops against specific IP or MAC address.
