A LANGuardian customer recently contacted us with an interesting solution for their complex core switch. They could not seem to set Ethernet 1-2/1/12 as a SPAN port, the customer told us they get the following error
“error: switchport monitor not supported for interface type”
One thing on the nexus is you have to set the mode of the destination interface (102/1/12) as a monitor port so in interface configuration mode run this command
switchport monitor
They have the connected the SPAN port now.
