I have a Cat3750G with 10Ge uplink ports. I am trying to span multiple ports to the 10Ge interface, which connects to a Mazu. The 10Ge interface does not show any error. However, the Mazu 10Ge interface show a ton of errors. TCPdump show many tcp checksum errors off the Mazu interface. I am not sure why the Mazu is showing ton of errors where the switch 10ge interface shows none?
Can the 10ge uplink port be configured for a destination span port?
Or what are the chances of compatibility issues?
BTW: traffic span to the 1Ge interface show no errors.
Cisco Command Reference shows
"If a 10-Gigabit Ethernet port is configured as a SPAN or RSPAN destination port, the line rate of the link decreases."
Does anyone know what it decrease to?
