Good day, I have an network issue with some unbalanced traffic using ECMP, i need to take packet captures from a 10GB interface in a mirror port. I would like to know if its possible and how or either how can i make this packets on a 10G switch interface from my laptop. asked 08 Nov '13, 07:59  RodrigoMorales |
One Answer:
If you mirror a 10G switch port to a 1G port of the laptop, you will most certainly flood the 1G port unless there is less than 1G/s traffic on the 10G port. As a result the switch will drop packets and you won't see them in the sniffer. If your switch supports ACLs on a mirror port (some Cisco switches do), you can define an ACL for the traffic you need to watch (src/dst IP?) and mirror only that traffic to the 1G port of your laptop. HINT: Please ask your local switch guru if that is possible with your devices and if it will create problems in your network (who knows ;-)). If it is not possible, you'll need a system with a 10G interface to capture the traffic of the mirrored 10G switch port.
