Problem configuring SPAN port on Nexus 7700

20 February 2019 Forum By: Darragh Delaney

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 that they get the following error:

“error: switchport monitor not supported for interface type”

One thing we noticed on the nexus is that 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.

The customer was then able to connect the SPAN port.
